Humat was an ancient Jedi who went insane more than 19,000 years before the Galactic Civil War. After leaving the Order, he fled with his treasures to Coruscant and buried them deep underground in a vault that became known as the Cell of Imu. This vault was rumored to be filled with many odd and arcane devices, as the ancient histories revealed that Humat had a penchant for alarming applications of technology and the Force. He installed a number of deadly traps in his vault and left behind numerous animal skeletons reanimated with dark side magic in order to protect the centerpiece of his collection: a talisman known as the soul stealer.
