IRW Decius (D'deridex class)

The IRW Decius was a battle cruiser (or battleship) of the Romulan Star Empire's Star Navy in the late 24th century. (Star Trek Encyclopedia, CCG: Alternate Universe)

In 2367, Barash created an illusionary world using real-world objects and people for Commander William T. Riker. In this illusionary world, the Decius, under the command of Tomalak, acted as a transport ferrying Jean-Luc Picard and Deanna Troi towards a rendezvous with the Enterprise|NCC-1701-D. 


 * The type is from the (battlecruiser) or from the book Starships (battleship). It is a safe assumption that the Decius could be an actual ship as the world created by Barash was crafted from the memories of William T. Riker.
