Aruans are a dog-like race hailing from the planet Kalhu. They are genderless, and highly advanced in both technology and magic. They tend to speak rapidly, often combining words and letters.
Only one Aruan has been seen - Solaar, so not much is known about them.
- The Aruans are familiar with dreamwalking and know of the annunaki.
- 'Aruan' is (probably) a reference to the village of Aru in Deliverance. In addition, Aru sounds like a wolf's howl. ('Arrrrruuuu...')
- Since the Aruans are genderless, the proper personal pronouns, possessive adjective and possessive pronoun for them are 'xe', 'xem', 'xyr' and 'xyrs' (instead of he/she, him/her, his/her, and his/hers, respectively).
- The Aruans believe that they are the most technologically advanced race in the Nusku-Girru Binary System; the annunaki believe otherwise.
