A large black dog that can phase through stone & other solid objects, the moddey dhoo wanders the halls of ancient castles on a regular schedule, keeping the inhabitants from breaking their regular routines, keeping them from sinning. Only a true saint of order can command a moddey dhoo. These large dogs are immortal within the walls of their homes, & any who break routine or sin in their castles will lose their voices, fall ill, & die within three days, unless they find redemption in some miraculous manner.
