The same galaxy, for everyone
There is no instanced copy of the map. When you claim a system, everyone else's map shows it as yours. When you move a battle line to the far side of a sun, every player watching that system sees it happen — ship positions are shared, live. Presence is a statement, and other players read it.
Diplomacy with teeth
Stances are directional: you choose who is ally, neutral or enemy, and so does everyone else — the galaxy is full of unrequited hostility and uneasy one-way friendships. Alliances open real mechanics: shared jump-gate networks, mutual defence, trade. Declaring an enemy opens others.
An economy between players
Trade agreements put real ships on real routes between two players' stations, paying both sides by distance flown. Loans move capital between empires. Even the NPC factions play politics — the Transport Authority runs a public jump-gate network and revokes access from anyone who makes an enemy of it.
War you can be inside
When diplomacy fails, combat plays out in a live 3D system view. Order your fleet like an RTS, or take the bridge of any ship over the Tachyon Link, watch the exchange, and fire your guns by hand. A galactic news feed reports the wars, the tier climbs and the collapses — reputations are made in public.
