|Out of universe information|
T'akaya is one of several aliens who pose as the spirits of a tribe of Salish people living on PXY-887. She appears to be the second in command and, when in the presence of the Salish, takes the form of a wolf.
During a visit to Stargate Command, Tonane is made aware of the spirits' true nature, and an agreement is made between Xe'ls and Tonane that the spirits will show themselves to the Salish in their true form from now on. (SG1: "Spirits")
