The Celegians are a species of intelligent scyphozoans native to Celegia, appearing as floating brains trailing a cluster of prehensile tentacles. The species are renowned for their wisdom and intellect, and they often travel far seeking to expand their knowledge.
Celegians evolved from ocean-dwelling ancestors, and developed a natural form of levitation similar to an organic repulsorlift generator. Their homeworld has a cyanogen atmosphere, which is lethal to most species but necessary for the Celegains, for whom oxygen is toxic. Because of this, when they travel offworld, they are normally encased in a chamber filled with cyanogen; this causes them appear as if afloat in a watery brine. Because of their fragile form and life support requirements, they are rarely encountered.
