The premise, in the publisher's words

Humanity spread across the stars and lived separated for centuries until ancient alien portals were rediscovered, reconnecting distant worlds instantly. These portals use symbol-based addresses, letting players travel to new planets and launch attacks through them. When the portals mysteriously collapsed, the galaxy fell into isolation and chaos. Now some of the portals are reactivating, unstable but usable, pulling factions back into conflict. You enter the story as one of the survivors rebuilding power, exploring worlds, and fighting for control of the few working gates.
