This castle floats somewhat hidden among the remnants of a planetoid destroyed ages ago by some ancient entity long forgotten by the outside world but is still discussed and possibly worshipped by the caretakers that remain. Merchants and adventurers are generally welcomed as supplies are difficult to come by. The caretakers do seem to have a substantial amount of gold, as well as an extensive library that contains arcane and divine knowledge. Anybody that spends a significant amount of time within the castle wills start noticing odd behavior from its inhabitants: conversing when nobody is around, cutting themselves and sucking the blood out or twitching randomly. Perhaps they've just been out in the void for too long.
