Celegian

Celegians are a non-humanoid species from Celegia. They appear to many humanoids as "floating brains." Very intelligent, they have a natural form of telekinesis that functions like a repulsorlift. They breathe cyanogen, poisonous to humans. (Conversely, oxygen is lethal to them, necessitating atmospheric transport chambers offworld.) They are relatively isolationist as a species.
