Amikiri the Unbinder
Amikiri had a very bad day prior to ever meeting the party, resulting in him being killed, and his skin worn by Tai Fong, a (now horribly dead) apprentice of the Imperial Alchemist. Walking in Amikiri's skin gave Tai Fong some (perhaps all?) of Amikiri's powers, and the ability to reliably pass as Amikiri. Amikiri's skin was subsequently laid to rest by Anto, but in the process, Anto, being the Wu Xing and thus inclined toward this kind of thing, acquired some of Amikiri's power and psych lims.
