The Dominion war comes to Star Trek Ascendancy... and the Alpha Quadrant will never be the same.

About Star Trek: Ascendancy – The Dominion War, from BoardGameGeek:

Through their Vorta commanders and Jem'Hadar super soldiers, the Founders rule as Gods, bringing order to the galaxy. The discovery of the Bajoran Wormhole brought this ancient civilisation onto conflict with the more youthful civilisations of the Alpha Quadrant. Expansion to the popular Star Trek: Ascendancy game, The Dominion War Variant adds the Dominion as a playable civilisation, the Bajoran Wormhole leading to he Gama Quadrant as a new area to explore and a Dominion war variant that changes the playing field by dividing the civilizations into two rival alliances with players striving to see their Alliance dominate the opposing Alliance. The expansion contains everything you need to add the Dominion, and another player to your games of Star Trek Ascendancy. Discover the Gamma Quadrant via the Bajoran-Idran Wormhole Systems, encounter new Exploration Cards, plus more Space Lanes and Resource Nodes! -description from the publisher
