Adarian

Adarians are sapient humanoids with blue or yellowed skin hailing from the planet Adari, although it is not believed to be their original homeworld. They are most notable for elongated skulls with a large hole that seems to penetrate the skull that serves no obvious evolutionary purpose. They also lack ears or a nose. Instead have adapted fine hairs that cover their head that are very sensitive to sound waves and their skin has glands located beneath the surface that allow them to pick up smells. Sharp, bony ridges edge around their oral opening, that likely are used for clipping their food, whether it is meat or floral matter. They also possess a distendable throat pouches that can be elongated like a frog to emit a loud call, used for communication over long distances.

Culture
Adarians are a stubborn people, and once they've made up their minds on one thing or another, it is generally almost impossible to change it for them. Society is based around a rigid caste system which they call "screel'sara", with the headquarters of their government being the Hall of Decisions, indicating that it likely operated as a judicial structure as well.

With the rise of the Galactic Empire, they signed a non-aggression treaty to gain neutrality in the Galactic Civil War in return for an unlimited amount of raw materials. As such, they were allowed representation in the Imperial Senate as well.

Technology
Adarians are known for a unique, advanced carbon-ice drive system.
