Tammiyat was born the village flibbertigibbet, never sitting still and always asking questions. This, combined with her innate sensitivity, led to her interest in psychiatry, and she began formal studies at the age of sixteen. At the age of twenty, though, Tammiyat received a vision of the previous Xian of Thought appointing her as his successor and telling her to proceed to the city of Tascan. There she met Mekai and Bernekes (the latter of whom she was instantly attracted to). She traveled with Mekai's group to join up with the other Xian.
