Promethean Chain

The Promethean Chain is a deific artifact, which allows one to to cast "Dominate Monster" once per day, and allows one to command dominated creatures to do tasks that would harm themselves.

it was held by Pietri Asano, and when he was killed, Crephi Ritsk performed a ritual to use it as payment to release her soul from colleterial. Due to her memory being erased, she is unaware that this caused it to be given to The Warden.
