The Raaif (Taxonomically Ira idolona; dubbed Wraiths by humans) were an aggressive Tier 3 race of near-reptilians, who roamed the outer regions of the Milky Way Galaxy. The Raaif were strong allies with the Gwam'l, after to the founding of the Raaif-Gwam'l Pact.
Biology and physiology
The Raaif were amongst the few sentient non-humanoids. It has been recorded that they were of a semi-aquatic, near-reptilian family, that would natural spend much of their lives submerged under fridged pools of liquid nitrogen on their homeworld. They would only leave these pools on hunts, as their desire for cold temperatures urged them to remain submerged unless the atmospheric temperature was within their ideal temperature range, which it wasn't on their planet. Even so, they were capable of surviving on land indefinitely, as their starship were extremely cold to reduce the need for their bathing in nitrogen.
