Star Trek Expanded Universe

The Spiritualists were a post-Dominion War Cardassian faction that vied for control of the Cardassian Union in the aftermath of that conflict. The faction was led by Parektar Varhet Enros Dorad.

They sought to revive religion and art to the forefront of Cardassian life. They gained much inspiration from the success of Bajoran civilization. They were amongst the weakest of the post-war factions due to their lack of military might prefer words over force. They formed a strong alliance with the Democratists and several smaller factions to form a "Cardassian Council" to promote law and order. (The Dominion War Sourcebook: The Fires of Armageddon)
