Once known as strict pacifists, Centaurans are crystalline jellyfish-like beings who have shown their capacity for hostility. Those of the homeworld, Centauri, are suspicious of the unenlightened rest of the galaxy, but curious enough to send researchers snooping around from time to time. Lovers of order and learning, they use their powerful telepathic talents to form a tightly-knit society. Natural abilities of self-levitation and glass-spinning make fantastic architectural works possible, and a three hundred and sixty degree visual field facilitates their powers of observation.
