Faction Dominion A conference on Deep Space Nine is cut short when unexpected visitors come through the wormhole...


The Lost Dominion story arc is a chain of cross-faction missions available to all factions. The quest is part of "The Galaxy at Large" side content. It takes place directly after the events of the Cardassian Struggle episode arc.

The recent Borg attack on Defera has revealed a need for forces of the Alpha Quadrant to sit together and discuss their strategy in defending the core worlds, as well as far-away colonies, from a rising Borg threat. Federation, Klingon Empire, Cardassian Union and the Deferi have all sent their representatives to Deep Space Nine.

But the Borg won't be your main problem - a Dominion fleet lost to time has resurfaced and is here to finish the job started in the Dominion War.
