Neogi
Neogi are described as classic evil "bug-eyed monsters" who patrol the universe in the game as an intelligent race, usually acting as slavers.
Ken Rolston describes the neogi as "a nasty slaver race with the physical appearance of a cross between a wolf spider and a moray eel. Each neogi individual is guarded by his personal umber hulk slave."
