Ghost

A ghost is form a soul occupies while it resides within the Land of the Dead. All ghosts begin their existence as larvae, and remain in this state for up to 99 days (1 full cycle). Most are collected by psychopomps and escorted to the Underworld for reincarnation, but some are not collected and remain trapped in the Shadowlands.
Only the dead can exist within the Land of the Dead, excepting certain magi, clerics and other entities whose powers allow them to tread there, and the inferi spirits who make up its fabric. The Ghostlands are separated from the Lands of Flesh by the Wall of Death, which was constructed long ago by the ancient god Yindaron. The wall possesses only one entrance - the Last Door of Falaz-Ur, god of the instance of death. This door is only to be witnessed by those who are dying at their very last moments.
The Ghostlands, also called the Shadowlands or the Land of the Dead, are not as the Dreamlands. although both are realms of the astral plane, inhabitants of the Ghostlands possess no capacity to make new memories or have new thoughts, making it a drab and lifeless place shrouded by mist and crumbling decay. The decrepitude of this realm represents the stagnancy and amnesia of its unfortunate denizens who are for the most part eternally confused and disoriented. Ghosts lead a terrifying existence, and as they possess souls they are prone to corruption by the demons which are able to break through into the Shadowlands from the bowels of Hell.
Spirits do not frequent the Ghostlands except for psychopomps serving the gods and demons looking to devour souls fresh and old.
As ghosts age, they become increasingly mad and confused as their memories become blended together, reordered or forgotten entirely, dissipating into the spectral mist of the bleak realm. If the corrupt soul of a murderer, rapist or some other form of foul defiler becomes lost in the Ghostlands, its rage and hatred persist even as their insanity takes hold.
Ghosts bear the appearance of their corporeal bodies at the time of their death, but bear instead the colour of their soul. Wholesome ghosts (few and far between) are known as "eidolons" and retain a clear, bright silver-white, mundane ghosts (shades) are a wispy grey and evil ghosts have darker shades. Black predatory ghosts are often termed "shadows" or "wraiths".
Most ghosts are spectres in that they can be removed from the Ghostlands by other entities and spirits. However, some are known as everwalkers and have been cursed by Niitoh to wander the barren mists for eternity. Most ghosts are not collected by psychopomps because of mass death, unexpected death or a lack of faith in any deity.
