The prison is a mostly ordinary prison (as far as a bondage prison goes), but one of the guards has a few... unconventional ideas for prisoner storage. Must have something to do with all those weird, niche kink books he has on his shelf. Regardless, nobody particularly wants his ideas spreading (nobody's quite sure how survivable they are), and nobody wants to piss him off either. So they just... toss him an immortal every time one rolls around. And try to tune out his stories at lunch.
