When the wizard Yrdris made a deal with a devil to take possession of an infernal tower spun from shadow in exchange for his eternal soul, he expected to find a way around the contract before his demise. He was wrong. Upon his death, the tower was whisked away to Hell along with everything inside. The problem: there were four beings still within who were, for various reasons, considered the wizard’s property, and thus now Hell’s. However, if they can help find the wizard’s soul, which is somewhere in the tower, they can return home!
