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. Lost Dominion is not available until level 65 for all factions.

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.

Upon completing each mission, they become available in the Mission Journal under the "Incoming Hails" tab, below the section heading "Lost Dominion" Mission Replay.
  • On console these missions can be accessed once you reach level 65. Found in incoming hails tab.
