Commander Pelia was a female Lanthanite Starfleet officer who lived on Earth from at least the 6th century BC through the 23rd century. She served as an instructor at Starfleet Academy before being assigned to Operational Support Services as chief fleet inspector, and later transferring to the USS Enterprise as chief engineer. While otherwise indistinguishable from a Human, Nyota Uhura was able to identify her species by her accent.
