In ancient times, the runelords of Thassilon used fleshwarping magic to create horrific soldiers, primarily those known today as sinspawn. Yet when Runelord Sorshen abandoned her domain below modern-day Korvosa and turned her back on her sinister past, fragments of flfleshwarp magic remained behind. Jaithe remembers her time in those hidden tunnels as dreams but knew even then she was different than the other sinspawn. Too human in form to fit in with the more monstrous fleshwarps, yet too alien in appearance to pass for human, she played the role of a mysterious woman who traveled the Korvosan hinterlands-at least until she met her new friends. Now, home is wherever her adventures take her.

At a distance, Jaithe looks like a Varisian woman until she speaks, at which point her lower jaw bifurcates like the mouth of a sinspawn. Her eyes are solid black, the fingers on her hands can bend both ways, and she has short frills of tendrils that writhe on the insides of her joints. When in mixed company, Jaithe can somewhat hide all of these physical features using careful draping of her billowing robes.
