Making Magic

There are a lot of ways to design a magic system, but to me the biggest decision to make has been Hard vs Soft. Should it have clearly defined rules and spells, or should everything be a little looser?

In general I’ve gone with the later, influenced by books the the Farsala Trilogy and the Sea of Trolls that I read while I was in middle school. I really like the idea of magic that consisted of some sort of hyperawareness of the environment and an ability to tell it what to do.

Because of this most of the settings I’ve made over the years have some sort of soft magic system with some animistic qualities thrown in. The problem? I’ve made them all the same. I’ve set aside a lot of projects over the years and I think it’s because I lost interest in them, because I kept making worlds with the same elements over and over again.

I also think that the stories I intend to tell in these settings end up suffering because of this. Too often the only cost to magic that I impose is feeling tired. That’s not really much of a cost. Why don’t I make it first born children or lost limbs, or beetles? There are a lot of possibilities that I have been largely ignoring.

So it’s time to switch to making systems that are a bit harder, something with more rules. As I’ve thought about it more I have realized that part of the problem is laziness on my part. The magic should make sense in the setting and add something to the story, and I’ve honestly run out of things to impose on the system I keep using again and again, but I also don’t want to take the time to define the costs and limits of the system. So I am making a very late news years resolution and I’m going to try some new things with my worldbuilding.

I’m thinking of starting with a little vancian magic first.

Red Suns: Faster than Light

I’ve often said that scale is an important thing to think about, especially in science fiction settings. It should be no surprise then that I spent a lot of time thinking about how I wanted faster than light travel to work in Red Suns.

For this setting I was aiming for a similar feel to the Forever War, where ships might be dozens or hundreds of light years from home and far from support. At the same time, I wanted star systems to be interconnected enough for interstellar trade and diplomacy to be practical.

Settlements end up clustered around major trade routes, even if the planets aren’t ideal.

Eventually I decided that ships in this universe will move between stars with something called the Bulgarin Drive. These drives work by warping space around a ship in such a way that the ship can move faster than light. Travel still takes time however, and in order to save myself from making any embarasing mistakes about distance I’ve decided that distances will be thought of mainly in the time it takes for a ship to reach its destination and that these travel times are partially determined by the skill of the ship’s navigator.

The effectiveness of Bulgarin Drives are strong affected by nearby gravity wells. Massive objects disrupt the bubble of warped space around a ship and so this determines what routes are possible. Before departure a ship may have to maneuver at sublight speeds for a signifigant amout of time before it reaches an adequate departure point, then it activated it’s Bulgarin Drive. Then months or even years later it arrives as close to it’s destination as local gravity conditions will allow.

This gravity-dependent behavior leads to three points that I am eager to exploit in worldbuilding and in story telling.

  • The limited number of acceptable arrival points in a star system creates opportunities to ambush ships as they drop out of FTL.
  • Smugglers and infiltrators can choose to take a longer route into a system if it means avoiding more well traveled areas of space.
  • In certain regions of space local gravity conditions align in just the right way to allow even faster FTL travel.

This third point is especially important for what I have planned in this setting and I’ve made a quick map of one of these Gravity Hyperlanes below.

Under normal conditions travelling from one end of this lane to the other might take a year for example, but because local conditions are just right the voyage can be accomplished in just six months.

My intention is for patterns of human settlement to be based around these hyperlanes. Easy travel will mean that colonies cluster around these lanes even if the systems are not ideal settlement sites, while the rare handful of Earth-like planets will be able to develop into self-sufficient units even if separated from these lanes.

After reading all that you might wonder how messages are transmitted. If a ship may take years to reach its destination then what about an email? Large amounts of data will still need to be carried by special courier ships, but short messages can be transmitted without needing to wait.

Bulgarin Transmitters, which work according to similar principles as the aformentioned FTL drive, are able to transmit short text-based messages nearly instantaneously with just two main limitations.

  • Messages have to be short. The transmitters require a lot of energy to work, so ships will have only have their transmitters active for short times. Receives can be kept on continuously however.
  • Messages need to be encoded. These transmitters suffer from a large amount interference so in order to receive messages intact they are transmitted in short bursts resembling old telegraph signals.

There are likely some flaws with this FTL concept that I’m not seeing, and it wouldn’t work for all settings, but I think it fits my rather well. It gives characters a way to communicate with some limitations, allows them ships to travel with reasonable speed. And most interesting to me, it will make spacers into a separate subculture of their own. Being gone from home for years and aging at different rates due to relativistic effects will quickly set them apart from their friends and family back home and I’m excited to explore this as I continue to build the setting.

Red Suns: Early Ship Design

In my last post I shared the design for my Lunar Cold War bunker built just before the beginning of world war three. This time, I thought I’d share my vision for some of the space craft that would have existed around the same time period.

The image above is meant to be applicable to both NATO and Soviet spacecraft designs. The specifics might be different but the general idea is the same.

My thinking with this design is that the vessel would carry five crew members; one pilot, three gunners, and one radio operator. The craft has two rotary cannons that make up its primary armament and also has a pair of missile pods that could be used for attacking space stations and other relatively immobile targets.

Also, you’ll notice that this vessel doesn’t seem to be designed with landing in mind. For the most part, this should would have operated from space stations or been reached by small cargo modules launched from Earth bring fresh crew and supplies.

For the most part this ship would operate in Earth’s orbit. The insides are cramped and the engines slightly under-powered, by that’s alright for a ship that will rarely go past the moon. Ships of this type might find themselves going on patrol, escorting larger ships, repairing satellites, disabling enemy satellites, and attacking orbital launch platforms.

I think it’s really interesting to envision the types of craft that would exist if we imagine the space race continuing beyond the moon landings. I have a few more ideas for these early ship designs, and I’ll be posting the setting’s FTL mechanics soon. So stay tuned for more updates!

What do you think about these worldbuilding ideas? What would you do differently? Let me know on twitter @expyblog.

Red Suns: A Retroscifi Adventure

Lately I’ve been working on a little side project titled Red Suns. It’s a retroscifi setting where the Cold War turns hot following a malfunction in one side’s early warning systems. By the time anyone realizes what happened it’s too late. Earth has been devastated by nuclear war and the conflict continues in orbit and on the moon’s surface.

Before the war began both the Americans and Soviets had been building an extensive infrastructure in space and on the moons surface. This included defensive lines on both sides of an agreed upon Lunar Demilitarized Zone. On the American side a large number and variety of defensive installations were built before the war started, the Soviets on the other hand were still in the process of building their fortifications when the war broke out.

After the war Earth ceased to be a viable home for the human race and efforts to explore space were quickly accelerated. As humanity spread throughout and beyond the solar system it continued to be divided along the old NATO/Pact line, with a handful of neutral and independent parties caught in between.

Some details still need to be worked out and I want to eventually insert it into some kind of lunar landscape. But you get the idea.

This particular bunker was designed with anti-vehicle operations in mind. A 20 mm auto-cannon and a trio of surface-to-orbit missiles make up its main armament. It had a crew of just four, who were rotated out regularly using the train seen in the bottom left.

Power was supplied by a small nuclear reactor that runs off of easy to handle uranium cartridges that can be switched out as needed by the crew. This reactor was capable of powering both this bunker and it’s neighbors in the even that the larger grid is disrupted. The bunker was also home to fairly powerful computer that provide’s guidance to the bunker’s missiles.

There were a few but not many options for crew comfort, you will notice a small kitchenette in the habitat section, and if you zoom in far enough you’ll see some personal items in some of the bunks.

This design did come with several issues however. While most supplied could be brought to the bunker by train, the missiles could only be reloaded by crews working on the surface. Similarly, while the turret could be operated and reloaded internally, most maintenance could only be conducted from the outside. In this timeline, these bunkers did their job until they eventually fell victim to orbital bombardment.

I’m still ironing out some of the basic ideas of this setting and I am interested in hearing you ideas. For example, the specifics of FTL have yet to be worked out, but I am currently mulling over slow(ish) modes of travel with a handful of faster “express” lanes. If you have comments or suggestions feel free to get in touch on twitter @expyblog.

I made a One-Page RPG!

Making an RPG is something I’ve been thinking about doing for awhile. A few months ago I started compiling a short setting book for Sprawling Iron, but that is taking awhile and it will be quite some time before I get all the writing for it done and finalize the maps. In the mean time, I’ve made this 1 page RPG and plan to make a few others as I have time. This one is called Before the Mast, and is set in Catatera, a mobile city made up of hundreds of loosely affiliated ships that endlessly circles the globe.

I’ve included the pdf here for anyone who wants to try it. There has been exactly 0 play testing, so any feedback would be very welcome. Find me on twitter @expyblog and let me know what you think!

Pirates…In Space!

Who doesn’t love a good brigand? Whether they are a robinhoodesque crusader or someone who is only looking out for number one, we seem to love pirates. So what about pirates in space? A lot of science fiction seems to treat space like an ocean. There are plenty of reasons to love these tropes, but they do present a challenge for worldbuilding. There is no reason why your science fiction can’t have hordes of swashbuckling brigands, but you should still attempt design your world in such a way that allows their escapades to make sense.

Treasure Planet had a wonderful age of sail aesthetic. Unfortunately, it does require a lot of worldbuilding to make believable. Source

For piracy to exist there needs to be something that is worth moving before star systems. Travel between planets, or even star systems, would be horrendously expensive, dangerous, and may take years depending on what kind of FTL your universe has. With so many risks inherent in moving goods from one place to another there has to be some reward.

In order for piracy to work there need to be reasons for a ship to stop. False distress calls are one way to do this, but might quickly reach its limit. The other way is to create a universe where FLT is accessible but still has logical choke points. There are a few ways to make this work. Portals are the easiest.

Portals provide natural choke point. Areas where ships have to pass through in order to get from on planet to then other. In the case of The Protectorate or Star Gate this is somewhat artificial. But in a setting like the one we see in The Interdependency naturally occurring portals can be found. Here Scalzi presents a universe where ships are able to travel between stars thanks to what amounts to a series of interstellar tunnels that still require large chunks of travel time between portal and planet. While traveling between portal and planet, a ship may fall victim to pirates or to mutiny, but one would hope that designated exit points would allow the navy to keep a close eye on affairs.

Another option for navigation to be difficult enough that everyone uses the same well mapped trade routes. Star Wars works this way. In Star Wars, or at least in Legends, trade is focused on a series of major hyperspace lanes. This means that finding new hyperspace lanes or knowing of secret ones has incredible value, and that a blockade of a given lane or the ability to intercept ships in transit can wreak havoc with the local or even galactic economy. While pirates are not likely to have the ability to stop ships in transit, common and well traveled routes makes travel predictable and gives pirates the opportunity to intercept ships as they drop out of FTL.

Star Wars features well mapped trade routes and interdictor ships capable of pulling vessels out of hyperspace. It makes finding new or secret routes an important plot point, even if travel times seem a little too brief. Source

Now that we’ve covered how goods might be moved between planets, let’s talk about the why. What could be worth flying between stars?

Information can be transmitted between stars, and even if data needs to be moved on some physical media there is not really a reason to send a person instead of a drone. A story about software pirates would be hard to pull off, so we need a universe where moving physical goods between stars is worth the immense costs and risks that come with it.

Ideally, every new colony will be founded with the goal of one day being self-sufficient. Over time the settle core of systems should become major producers of food, finished goods, and raw materials, and this settled core should then be connected to the newer colonies by a network of trade routes designed to prop these new colonies up until they can support themselves. This begs the question of why the core planets care about founding and propping up these new colonies. For this reason I think for most pirate settings it helps to assume that trade occurs between a mix of developed worlds and struggling colonies, that colonies are set up with the goal of producing a specific resource, and that monopolies prevent many colonies from becoming fully self-sufficient.

Now let’s go through some good space piracy tactics. Assuming that colonies are dependent on their home worlds for support.

  • Distress Calls – space is huge, and dangerous. If a ship malfunctions in transit there might be little chance of rescue or of witnesses. A distress cal would not be out of place, and might even be seen by less than scrupulous captains as an opportunity for some illicit sabotage. All our pirates need for the ruse to be convincing is a an appropriately derelict ship. Once within range the pirates will be free to disable the approaching ship, or wait until a salvage team boards and can be taken hostage.
  • Sabotage – the easiest and safest way for pirates to operate would be to have contacts back on the home world. A few port workers on the payroll could ensure that incoming freighters come loaded with all manner of malfunction. Then when a freighter’s engines fail and its left drifting in space our favorites brigands will approach ready to “help.”
  • Mutiny – a mutiny could happen for a variety of reasons. The crew could be under paid and overworked, or could have cut a deal to steal their ship’s munitions cargo and sell them to local rebels, or might be trying to steal the ship’s load of vital pharmaceuticals to help their families instead of the local oligarchs. Mixing motives here offers opportunities to put a mix of corrupt and sympathetic characters in the ranks of the mutineers and play their conflicting personalties against each other.
  • Ambush – many flavors of FTL result in natural choke points. This is especially true if portals are involved. Incoming ships would have little idea of what is actually waiting for them just beyond the portal’s exit, and would have to trust in local security. In developed systems the jumping off point will likely be well policed, but worlds that exist on the periphery are much more likely to experience gaps in protection. FTL systems that require cool down times will result in similar, but likely more dispersed choke points. This gives pirates an opportunity to ply their craft with less threat of detection. Although locating targets would be more difficult in this situation.
  • Privateers – people love to make money and governments love to save costs if they can. Disrupting an enemy’s supply lines can be hugely advantageous, but in the vast expanse of space no force will be able to be everywhere at once. Privateers offer a low cost option to hinder the enemy’s activities without putting a faction’s own ships at risk. There are other advantages as well. In a setting where spaces are vast and travel times long, armed conflicts could go on for decades. Employing privateers allows governments to put distance between themselves and the actions they take against rival factions.

There are almost certainly other strategies for our space pirates that I have over looked. Technological advancements would surely create new opportunities for our brigands. If you have any ideas for how pirates could work in the far future I would love to hear about them on twitter @expyblog.

Five Tips for Fantasy Map Makers

1. Mind the Rivers

Some worldbuilders spend years getting their plate tectonics and ocean currents just right. All of this can be fun, but you can make a convincing fantasy map without it. The thing you should really focus on is rivers. No one really cares if your ocean currents are off or your mountains aren’t in the right place. Rivers have an intuitive aspect to them that no other geological feature can match and because of this mistakes are easy to notice. To put it simply, rivers flow from higher elevations to lower ones. Most often rivers will flow into lakes, oceans, or other rivers. Rivers do not flow into a lake, wait around awhile, and then flow into a different river.

This is important because an incorrectly drawn river is jarring to look at even if you don’t know why, and because rivers are hugely important to civilization. Most major cities are built on rivers in order to take advantage of the farmland and transportation that they provide. This means that rivers can serve as a vital plot device, and as such their portrayal should not be ignored. Of course all of this can be ignored, it is your world after all, but I would advise making sure that you have a good reason for doing so.

2. Make Your Map Fit Your Story

People grow to fit their environment. You wont find horse-mounted nomads living in the mountains or naval powers in the middle of the desert. People do the best they can with the hand they are dealt. In fiction, we can decide what that best is and determine a hand that will enable it. There is of course fun to be had in drawing a map and simulating the evolution of civilization from the stone age to now, but that is not what most of us are doing. Most of us have a story we want to tell or an idea for a world we want to depict. There is no reason then to design a landscape that does anything other than to enable the story you want to tell. If you want your countries to be fighting for control of a major sea lane they there better be access to water and natural choke points. If you want your characters to venture to a distant mountain and fight a dragon then you better include a mountain or two within reach.

3. Choose a Realistic Scope

A lot of us like to think big. We draw a map of an entire world, solar system, or even galaxy and then set about filling all of it in. The problem here is that you probably wont use most of what end up writing. Trying to fill every corner of a world with detailed is fun, but ultimately futile. Above all remember that map is meant to be a reference for your players or readers, and the focus of the story is likely to only concern a small corner of the world.

Lately I have preferred to start with a single region or country that is going to be the focus of the setting. Once I have a solid idea of what that country will be I start to fill in its neighbors. Unless I have good reason to, I try to avoid writing detailed histories of these neighbors. I make a brief summary of their current state and history, and after that I try to only flesh out the aspects of this neighbor in areas where they intersect with the story I want to tell.

4. Pay Attention to Natural Barriers

Rivers aren’t the only feature on the map that shape a civilization’s development. What hinders movement in your setting can be just as important. Swamps, mountains, deserts, and seas are all important in imposing limits on an empire’s expansion, providing shelter for smaller groups, and providing places to hide all sorts of interesting dungeons.

Once barriers are in place, routes to circumvent them gain immense strategic and economic importance. Mountains, swamps, and other remote areas might also be where your world’s exiles and hermits choose to live away from society. Both of these provide opportunities for interesting conflicts or quests in a story or campaign. Characters and armies can be sent to secure and defend mountain passes, or might discover that the old hermit living in the swamp has the answer to all of their problems, but reaching him can be an entire adventure in itself.

5. Don’t Be Afraid to Change Things

Getting wrapped up in the worldbuilding is easy. It’s also easy to be disappointed. The finished product rarely resembles the initial concept and there is nothing wrong with that, except of course if you are not happy with it. If you getting into your worldbuilding and you realize that you put a mountain in the wrong place or your cities are too far apart. If you begin to get the feeling that your map is keeping you from writing the conflicts and plot lines that you want then by all means change it. Starting a new project by drawing a map can be a great way to start, but that map should not be a cage. Sometimes we need to make revisions, and it doesn’t do any good to get too attached to a map you have drawn. Keep it of course, even discarded ideas can be useful later on. Don’t be afraid to retcon the entire map if it no longer serves its intended purpose.

Subreddits For Creatives

Reddit is one of the biggest sites online these days with so many subreddits available that you are almost guaranteed to one tailored to your interests. Think of any hobby or weirdly specific meme format and there is probably a subreddit for it. So what if you’re a writer or worldbuilder, what are the best subreddits for you?

Worldbuilding

It should really be no surprise that r/worldbuilding ranks among my favorites. The subreddit has grown significantly in the past few years and welcomes worldbuilders of all levels of talent. New artwork, discussion posts, and resources are posted daily. If you stay on long enough you’ll begin to see who the regular posters are and get to watch their work grow and develop over time. My preferred way of browsing this subreddit is to sort by new and look for discussion posts. Participating in brain-storming sessions or answering questions about your own world is a great practice and a good way to finally flesh out parts of your setting you may have overlooked and been putting off for later.

Imaginary Network Expanded

The Imaginary Network is a cluster of related subreddits dedicated to posting all sorts of art with credit to original artists. I like to browse through it when I’m facing off with writers block. My personal favorites are r/ImaginaryBeasts for making up new flora and fauna, r/ImaginaryBattlefields for thinking up climatic showdowns, and r/ImaginaryStaships for when I need my daily dose of SciFi.

Writing Prompts

When you feel like writing but don’t know what or you’re just looking for a challenge, r/WritingPrompts is sure to help with its long list of user-submitted starting points that range from established fandom to completely originial premises. The subreddit also hosts contests from time to time and has been the route through which many users have gotten their writing noticed. Writing a response to a popular post it can be a good way to get your writing more exposure online. Several frequent posters maintain personal subreddits to showcase their writing. Unfortunately, popular promts are often highly specific or tied to a certain fandom. If this is a deal breaker to you prefer something with a little more freedom then try the less popular r/SimplePrompts.

Map Making

If you’ve made a battle map for your D&D campaign, a fantasy island, a political map of your alternate history scenario, or you just like making maps then r/mapmaking might be the place for you. Like r/Worldbuilding it’s welcoming of all skill levels and is a great place to post if you’re in need of advice or feedback. Just make sure you have all your rivers drawn right before you post.

How to Build a Country

A lot of us like to bang our heads against the wall trying to design sprawling worlds to rival settings like Forgotten Realms or Middle Earth, but attempting a project with such a large scope takes time and may very well lead to disappointment when progress doesn’t come as quickly as hoped.

The good news is that you don’t need to design and entire world. Plenty of interesting stories can be told that take place only in a single valley, forest, city, forest, or even house. If you are designing a setting for your stories to take place in the you need to be honest with yourself about the story’s scope. Figure how much space your characters need and stick to it, make a few one-line summaries about far off lands that you can expand on if needed. Doing this will help you keep your goals in mind and prevent your worldbuilding process from taking over your writing process.

When it comes to worldbuilding there are two basic methods; Top Down and Bottom Up. The process I am describing here is called Bottom Up, where you start by building up a small corner of the world and then expand in scale to fill in the rest of the map. If you have a story to tell and don’t need an entire world to do it, this is where you would start.

For me, if I am going to build a world Bottom Up then I prefer to start at the national level. Even if I only have need of one or two locations in it, I like to have an idea of where my characters might be from and a general idea of events elsewhere that may have an influence on the course of their lives. This approach also makes it easier to focus on a world’s minutia, if that’s what you’re into, rather than getting distracted by what might be hiding in distant lands.

This list of questions is meant to help focus the scope of a worldbuilding project, and help you to decide on what matters in your setting and what does not.

Where is the country located?

Where a nation is plays a huge role in its success and failure. Just as it is hard to become a major naval power without easy access to the sea, it is also hard to build significant influence abroad if your tiny kingdom is sandwiched between two giant superpowers.

Rivers create avenues for trade and enable farming, mountains provide natural barriers and refuges for outcasts, forests and swamps provide a ready source of timber and place to hide all the things that go bump in the night.

Once you know what stories you want to tell, you can design your geography to create the setup to make it possible.

Where are the people from?

Mass migrations and invasions are hugely influential in our own history and can create divides within a populace that can last for centuries. A small group that speaks one language ruling over a much larger population is a situation that is almost guaranteed to spark conflict. Migrations can also explain why certain languages are spoken, or why your country has five different holidays on the same calendar day.

Going back further, these migrations can play a vital role to constructing the country’s mythos. Perhaps these people were once nomads and settled down after receiving the sign from the gods. Or maybe some of your characters are refugees that have been taken in and are trying to survive in an unfamiliar and possibly even hostile land.

Where are the major cities?

When your farmers go to market, where do they go? Where are the train junctions? Where do people send their children off to school? Where do they go on pilgrimage? What are their industries?

Besides the obvious points that major cities are home to centers of military and political power, they may also be the centers of regional rivalries or home to minority ethnic groups. People from different cities might speak different dialects, wear different cloths, celebrate different holidays, or speak with different accents.

Regionalism is an important part of this. No country is truly homogenous. The monolithic nation states today only seem that way because of decades if not centuries of effort expended to create a sense of national identity. In reality separate regions within a larger country may be fierce rivals, and may even hate each other. Or may compete for lucrative contracts and trading partners. In a nation with less centralized authority, these cities may even enter into their own treaties with foreign powers.

What do the people believe?

Religion can serve to unit a populace around a core of shared goals and values, or it can serve to drive a wedge between different segments of the population. Deciding what people believe goes a long way towards explaining their motivations and their biases.

Similarly, consider whether this country as some sort of national mythos around its creation. Does it see its history as a long and drawn out struggle for freedom, or do its leaders preach a vision of the future in which they dominate the continent? Just like religion, founding mythis can act as powerful motivators.

Who is the government?

Few things tell you as much about a country as who gets to participate in government and there are lots of interesting spins that can be put to make an established system of government unique.

First decide who has the power, the people, hereditary nobles, the king, the church, the rich. The possibilities are nearly endless here and you are free to imagine all sorts of checks and balances, traditions and laws surrounding voting, and even past civil wars that have shaped politics in the country’s “present.”

Once you know who calls the shots, you can start to imagine who might be demanding a larger voice in government.

Who are the country’s neighbors?

I warned before against trying to create an entire world when you only need a small corner of it. That said, it’s important to know where the nation stands. A quick list of what countries border this one, who its allies and enemies are, and who buys what from who will help you get a clearer picture of that larger world.

If the country’s neighbors are likely to play a larger role in your story you might spend a few more paragraphs on past conflicts, customs, and clothing so that you can quickly create foreign characters for your protagonists or player characters to interact with.

Armed with this brief outlining you’ll be able to quickly incorporate one line references to far off places. Small details like this are a huge part of what gives a setting sense of size and depth.

Conclusion

Do you prefer this approach, or would you rather build your worlds from the top down?

There are many more questions that can be asked to facilitate this Bottom Up approach. Find me on twitter if there is one that you’re especially fond of or wish I had included.

So You Want to Invade a Planet

Look up at the stars. Somewhere out there someone is doing something that makes you don’t like and you want them to know just how angry it makes you. How will you do it?

In this scenario I have assumed that FTL is somewhat slow but still possible and that the end target is a developed Earth-like world.

1. Assemble your fleet.

Decide what your goals are, is this meant to be a raid against the planet or do you plan to occupy territory? Make sure you don’t leave your own world undefended when you assemble this fleet and make sure the fleet is equipped to deal with unforeseen circumstances. The ships may be gone for several years and once they leave resupply will be difficult. At least some of your ships should be equipped to harvest local resources and grow food or manufacture munitions.

2. Get Underway

Timing is important. The planet you’re going to might be years away. The main fleet should leave together so that you don’t scatter your forces too much, but it may be a good idea to send a few smaller forces ahead to scout your target. A lot can change while in transit the early you find that our the easier it will be to change course and make new plans.

You may also consider sending smaller detachments after the main force. These could be mostly resupply missions, spaced out so that the fleet can depend on resupply at scheduled points during the campaign.

Remember that depending on the technology available to you there may be a substantial period of deceleration as your approach the target system. This means your engines will be pointed towards your destination and sending out a lot of easily detectable heat and light. If this is a system that gets a lot of interstellar traffic it might be possible for all of this to be lost in noise, though at this point it would be better to assume that you have been seen and that there will be ships waiting for you when you arrive.

3. Fight Your Way Through the Solar System

Space is big, dark, and cold. Any ship is going to give off a huge amount of heat as it moved through space, especially when it starts to starts to decelerate as it approached its destination. A single ship might be overlooked, but a large fleet will be hard to miss, so don’t worry too much about the element of surprise. You can’t really hide your fleet anyway.

What you can do is make the enemy unsure of your intentions. Split your fleet into several battle groups and send them on different trajectories through the target system. This robs your enemy of a single large target and the potential for a decisive battle and allows your fleet to hit multiple targets roughly simultaneously. An advanced world probably has several populations centers through a single star system and you won’t want give your enemies a chance to attack you from behind while you’re busy landing troops on the planet.

When you do enter the system you should consider employing long range missiles. Unmanned missiles are smaller and can move much faster than manned vessels, giving them a better chance of making it through your target’s defenses. The missiles can be used to strike at targets well in advance of your fleet’s arrival to minimize the risk to your own ships.

4. Establish Orbital Superiority

By the time your ships reach the target planet their defenses will have hopefully been greatly weakened by missile strikes and their fleet will have been dispersed to deal with the multiple battle groups you’ve sent through the system. If the planet has any space elevators or sky hooks now would be the time to seize them. Ships should be positioned so that the entire planet can be observed.

5. Find Your Targets on the Ground

You probably lack the troop numbers and the will to fight for every inch on the planet’s surface. Before landing begins, select targets on the ground that might pose a threat but are also not ones you care about owning yourself. These targets should all be destroyed from orbit before any landing operations begin. Munitions used here need not be nuclear, a few metal rods dropped from orbit should be more than enough.

If multiple continents on the planet’s surface have been settled it may be worth targeting any infrastructure that might connect them in order to hinder the enemy’s ability to move their troops around. Of course this assumes that you do not want that infrastructure for yourself.

6. Deploy Ground Troops

Ground troops should only be deployed to secure targets that you have decided are vital to the success of your campaign; planets are just too big to consider anything else. Power plants, space ports, terraforming stations, and government buildings are all worthy targets as just owning them will give you control of other areas and may yield valuable intel.

The scale of the landing really depends on what your goals are. If you want to disable a few critical systems while securing intel and prisoners then you may not need to deploy more than a few thousand troops. If you plan on holding territory for any length of time then tens or even hundreds of thousands may be needed.

7. Pack Up and Leave

Annexing an entire world requires a massive commitment of resources and millions of soldiers over many years may be required to completely secure a world. If regular bombardments do not phase you then this could conceivably be accomplished with a much smaller force at the risk of rendering large segments of the surface uninhabitable.

If your goal was just to knock the system out of action to prevent them from supporting your enemy’s war effort then your options are much simpler. Once your troops have secured whatever intel or prisoners you wanted on the surface you can extract them, blowing up space ports and even power plants as you leave. Space elevators and skyhooks can be demolished by the fleet once troops have been fully evacuated.

All those space ports and elevators will likely take many years to fully replace, but to hinder outside relief then nothing quite beats a selection of orbital denial weapons (You can keep your fleet in orbit of course, but if this is part of a larger conflict then the ships are probably needed elsewhere).

A minefield in space is not going to look anything like what we see on Earth, and mines as they have been depicted in Star Trek several times would be hard to make work. Space is big and mines are tiny, you want your minefield to depend on more than just chance collisions. Here I think a swarm of small, automated satellites would come in handy.

Satellites could be deployed in order and throughout the system and outfitted with various armaments including missile launchers, rail guns, and gamma ray emitters, and if you’re more a fan of the classics then explosive satellites could be designed that would then release shrapnel to clear their orbits of enemy ships.
