IRW Deranas
Class:	D'deridex-class
Registry:	IRC-1959
Affiliation:	Romulan Star Empire Romulan Star Navy
Status:	active (2366)

The IRW Deranas (IRC-1959), also known as the IRW Trennis, was a Romulan D'deridex-class battle cruiser (or heavy cruiser) in service to the Romulan Star Empire's Star Navy in the 24th century. During the mid-2360s, the Deranas was commanded by Commander Tomalak. (ST reference: Star Trek Encyclopedia, CCG reference: Second Edition, ST roleplay module: Starships)

In 2366, the Deranas violated the Romulan Neutral Zone in order to rescue the crew of the scoutship, Pi, which had crash-landed on Galorndon Core. (TNG episode: "The Enemy")

A few months later, the Deranas was one of several warbirds that remained near Nelvana III and were part of the plot to reveal Admiral Alidar Jarok as a defector. (TNG episode: "The Defector")

The Star Trek CCG named this vessel Deranas, but the reference book Starships called it Trennis.
