The Nasat are a four-armed race of methane-breathing humanoids, Nasats are native to the planet Nasat. They were easily recognizable by their large, cone-shaped heads and the breathmasks they wore whenever they are in an atmosphere that lacks sufficient methane. Beneath their protective suits, Nasats had transparent skin and large, black eyes. They kept the location of their homeworld a heavily-guarded secret, protecting its independence with their lives if necessary. As a people, the Nasats were secretive and quiet. Although generally peaceful in nature, Nasats often reacted swiftly to any threat they encountered, whether real or perceived.
