You rule one empire inside a persistent galaxy, starting with a single homeworld and a fog-of-war map. Give your orders, and at a scheduled moment the galaxy resolves them all at once.
Not a pitch deck. These are the systems the galaxy runs on right now, described the way you will meet them.
Every planet and moon is described across six environmental axes: temperature, pressure, atmosphere, gravity, radiation, toxicity. Every species has its own comfort range on each, set by the homeworld it evolved on. There is no universal good planet, only worlds that suit you or kill you, and two players can look at the same rock and reasonably disagree.
Settle somewhere hostile and your colonists start dying, unless you build the specific structure that answers that specific problem. Nothing is a general-purpose fix, and each structure protects only so many colonists — a growing colony keeps building. A world that is wrong in three ways needs three answers. A harsh world is a real option, just a permanently expensive one.
Colony population is simulated every tick, not stored as a number that ticks up. It grows where you have built the housing to support it and dies where you have not sheltered it, and when it has room to grow, it never grows by exactly the same amount twice. Two colonies founded on the same day drift apart. You can load colonists onto ships and move them, which is how you get a young colony on its feet instead of waiting years of ticks.
Orbit is not ownership. You train garrisons of infantry, armour and artillery, carry them on troop transports, and land them. An invasion resolves over two ticks: you establish a beachhead, and the fight resolves after. The defender gets a tick to react, which makes invading a commitment rather than a click.
An academy at one of your colonies offers officers to recruit. Post one to a fleet that carries a Command Bridge, or to a colony's industry, and they gain experience for the battles, journeys and production they take part in. An officer whose last ship is retired at your own colony steps ashore; one whose ship is destroyed is lost with it.
A free-form design with no drive is an orbital installation. Build it, crew it from a fleet, tow it into the orbit you want, and — for a yard — build ships in orbit without a colony shipyard underneath.
The race you choose when you join a galaxy decides the kind of world you start on, and its comfort ranges decide which worlds are hostile to you specifically from the first tick.
NPC empires are not scenery and not obstacles. They hold colonies, expand, build, run supply routes, defend themselves and fight each other, using exactly the same orders and rules a player uses, with no special privileges. Some settle, some explore, some raid, some just drift, and they can form factions and go to war. You arrive into a galaxy with history, not an empty board.
A tick-based game should not punish you for sleeping. Colony managers keep a colony developing on a build priority. Submitted orders resolve on schedule whether you are there or not, and saved plans let you draft orders ahead — they submit only when you say so. Convoys, patrols and standing routes re-issue themselves each tick, including routing across multiple warp jumps. Caretaker keeps your empire developing while you are away, and hands it straight back the moment you return.
Every planet and moon is described across six environmental axes. Every species has its own comfort range on each, set by the homeworld it evolved on. A world that would kill one empire's colonists is another empire's paradise.

TerrestrialHome, for someone
Gas giantNot for colonistsFour loops that feed each other. Knowledge becomes territory, territory becomes industry, industry becomes fleets, and fleets decide who keeps what.
The map is not given to you. You take it a hop at a time. You start with a single homeworld and a fog-of-war map. Surveying a warp node tells you its partner on the far side and the name of the system it leads to, and nothing else. To learn what is actually in that system you have to warp through and scan it. Each of those is one tick.
Find a world your people can actually survive on. Habitability is relative to your species, so expansion is a judgement call rather than a checklist. Find a world your people can survive on, send a colony ship, and settle it. Settle carelessly and the colony dies.
Turn a rock into a power base. Build the extraction, storage, shelter and shipyards that make a colony worth defending. Population grows where you have built to support it, so development and survival are the same problem.
Position fleets, set your stance, defend what's yours. Fleets fight when hostile forces meet. You set each fleet's stance and your empire's standing toward others in advance, because you will not be awake for every contact. Every battle is resolved by the game itself, under identical rules for everyone. There is nothing to out-click.
The galaxy does not run continuously. It advances on the tick, and everything that happens in a tick happens to everyone at the same moment. Ticks run on a fixed schedule, and every galaxy has its own tick rate. Here is what one tick looks like from your chair.
Read your colonies, your fleets, the part of the map you have revealed, and the reports from the last tick. Reports can also arrive as email, in a large-print format with a complete plain-text version, which is a supported way to play rather than an afterthought.
Issue orders. Move a fleet, scan a system, settle a world, build a structure, start a ship, load cargo, train troops, launch an invasion. Draft orders ahead as saved plans — they submit only when you say so — and cancel anything still pending while the tick is open. You can also do this from Discord: link your account, check galaxies, join one, submit and cancel orders, review what is pending, and get your turn sheet.
Orders are intent, not action. They sit until the next tick. This gap is the game. It is what makes a bad decision a real one, and it is why a player in a different timezone is not at a disadvantage.
At the scheduled tick every empire's orders resolve together, under the same rules, in the same moment. Yours and the NPC empires' alike, with no special privileges for anyone.
Reports tell you the outcome. Some of it will not be what you hoped. Your map has grown, or your fleet has not come back. Nothing about the next tick is decided yet, so reroute the convoy, change the stance on the border fleet, start the shelter instead of the extractor. Then close the app and let the galaxy come to you.
The gap between deciding and resolving is the game. It is what makes a bad decision a real one, and what means a player in a different timezone is not at a disadvantage.
None of the following is in the game yet. No dates, no order implied, and nothing here is a promise. It is where the design is heading.
Astral Sovereignty is playable now. The first alpha galaxy is running, free, in your browser, and you can join it today.
Everything on this site is built and running, and it is still an alpha: systems are being added and changed while people play. You share the galaxy with NPC empires, which play by exactly the same rules you do.
The Discord is where development happens in the open, and where new galaxies are announced.
