Ghosts are the spectral remnants of intelligent beings who, for one reason or another, cannot rest easily in their graves. A ghost normally resembles the form it had in life, but sometimes the spiritual form is altered. For instance, the ghost of someone who believed he or she was evil might look a bit demonic. Because they are incorporeal, ghosts may be hit only by magical weapons.

Ghosts are the spiritual remains of extremely evil humans who have been denied the ordinarily inexorable movement of their souls to the outer planes of existence after discarding their mortal shell. This sundering of their metaphysical essence creates a foul thing, roaming dark and desolate places, existing in both the æthereal plane and the prime material, seeking to slake a thirst that can never be sated. This exigent need for living essences is what drives these spirits into contact with mortals.
