Most ghosts bear markings of some kind identifying the cause of death: bruises about the throat for a strangling victim, a persistent cough for a tuberculosis sufferer, perpetually wet skin for a drowning victim. While ghosts usually appear much as they did in life (save for any death markings), this appearance is a lie. The body of a ghost is not formed of flesh, blood and bone. Instead, a ghost has a corpus, a matrix of Essence attuned to the Oblivion-tainted nature of the Underworld.
Despite the presence of death markings, a ghost usually does not bear the physical injuries associated with her cause of death, or at least not to the point of debilitating her in any way. A ghost who died of old age may still appear stooped and wrinkled, but she will move with the same alacrity and purpose of the ghost of a much younger person. There are occasional exceptions to the rule, however, especially in the case of mortwights, ghosts whose deaths were so wretched that the poor souls immediately became spectres upon entering the Underworld. Many mortwights have grossly deformed bodies, pitiful reflections of the ghost's selfloathing and bitterness.
