ritual we're open! i'd love a new protégé/project for this demon to tinker with (this should be a younger person, either new to their abilities and in need of guidance or otherwise alone and willing to become dependent on a demon's good graces), employees at his hotel (a right hand person would be aces, species up to you), descendants of the people who bound and imprisoned him for a thousand years to torment and/or twist to his own purposes (species up to you, but probably not a demon), and hotel guests or long term tenants (any species!)
