The SS Ephialtes was an Antaeus-class civilian superfreighter operating in the 23rd century. It had a top speed of warp six and functioned primarily as a colony support vessel. It was commanded by Captain Alodae and had 25 crew and officers. However, at the Iremal Cluster, the freighter was intercepted by the IKS vaQjoH and ordered to surrender and prepare to be boarded. The Klingon's were thwarted from their attempt at plunder by the USS Enterprise which, acting on intelligence from Vanguard, had been lying in wait in a planetary debris field nearby.
