The Citadel is one of the powerful cores for the Purebreds: secrets that the population doesn’t need to know are in there. Is now the time to reveal all the truths? Freedom cannot wait! Are you ready to challenge the Purebreds’ Power? With The Citadel Expansion, you can play your D.E.I. games in a new mode: The Citadel! It also adds four alternative Leaders to the Base game Factions, plus one Leader and one Drone to the Purebreds faction (included in the Kickstarter Exclusive Old London Expansion).
