Didoan

The Didonians were a peaceful humanoid race native to Dido. When a spaceship crashed on the planet in 2493, they met with the surviving passengers, but were killed along with them by Bennett to cover up a murder he had earlier committed. At least two of the Didonians survived, and when they confronted him, he backed away in fear and fell from a rock ledge to his death. (DW: The Rescue)
