The IRW Trolarak was a D'deridex-class Romulan warbird in service of the Romulan Star Empire's Imperial Fleet in the late 24th century.
History[]
By 2369, the Trolarak was under the command of Galathon. In that year, the Trolarak became involved in the race to unravel the DNA puzzle discovered by Professor Richard Galen after intercepting communications between the Cardassians and their informants. The warbird, presumably under cloak, followed the USS Enterprise-D in its search to Vilmor II where the final piece of the puzzle was located. (TNG episode: "The Chase"; CCG set: Energize)
