Star Trek Expanded Universe

The Bernakians were one of the main post-Dominion War Cardassian faction to vie for power for the Cardassian Union. The faction was lead by Gul Bernak, a hardened military veteran he wanted to dissolve the Union, expel all non-Cardassians from Cardassia Prime and seek internal solutions to Cardassian problems. Bernak planned to use other worlds as targets for military conquest and economic exploitation rather than establishing an empire. (The Dominion War Sourcebook: The Fires of Armageddon)
