The Otevrel were a species native to the Alpha Quadrant. They were characterized by a cylindrical body roughly two meters tall and narrowed in middle, with a green exterior and rows of finger-like tentacles a third of the way up and a third of the way down their bodies. The Otevrel constructed artificial planets.
By 2381, at least one Otevrel, a male named Relkdahz, was serving in Starfleet as the chief engineer of the USS Robinson. (ST - Typhon Pact novels: Rough Beasts of Empire, Plagues of Night, Raise the Dawn)
