Decurion Ahrrek was a Romulan engineer at the time of the Earth-Romulan War. In 2159, Ahrrek was part of the military force that took the Ejhoi Ormiin base located on Gasko II. Ahrrek reported to Terix that the warp seven capable vessels in the base were not actually capable of reaching warp seven because key components had been removed from the ships' engines.
