Ortezo

Ortezo and Atza were passengers on the Hyperion III. They prevented the ship from being plunged into the black hole of Tartarus, but then hijacked it. They were in league with Rudge to steal the ship's vionesium cargo, which they saw as having been stolen by the Earth Empire from Mogar. They were killed by Doland. (DW: Terror of the Vervoids)
