The first individual buried in a temple or a cemetery will sometimes rise up as its ghostly protector. To avoid this fate, a dog is often buried first. A Grimhost will lurk invisibly and silently. It might chose to appear as the living person it once was to gain information or assistance, or to issue a warning. It will always appear as a ghostly shade to protect their charge.

A grimhost will retain the abilities it had in its former life, however a former Magic-user will only be able to cast spells if a spellbook is left available for it to use. A grimhost’s weapon is a manifestation of its essence and is considered a magical weapon, but it does not exist on its own.
