Crewman Ylacam was a male flight technician first class assigned to the USS Aventine.

In early 2381, Ylacam was logged in to perform routine maintenance on the runabout USS Seine where he was found dead and partially dematerialized. The Caeliar Arithon, who had been stuck on the wreckage of the Columbia, had transported himself to the Aventine and hid in the Seine and killed Ylacam for sustenance.
