Urrau

The last-born child and only son of Queen Iau: also called "the Great Cat", "the Great Tom", "He Who Scars and is Scarred" and "the Lightning-Clawed". In feline tradition, Urrau became Iau's mate and consort, and killed the Old Serpent under the Tree by the River of Fire.

Urruah's name is a pun on Urrau's. (TBONWM et al.)
