The mermories of the dead and hoffic stituations, Ghosts are the living memories, seeking to be remembered.
But their state has made them so very different. And their are old ghosts that have Drank form the rivers of the underworld, and thusly have become
little gods of death.

How they haunt

All ghost, even those that have drank form the Rivers of the underworld, have Anchors.
Anchors are objects, places and people who resnats with the ghost mermory.
Ghosts are able to influance their anchors, but if they leave are surronding their anchor will slowly drian them,
and if they anchor is desotryed then they are sucked down into the underwold.
The Underworld, also called by many other names, is one of they only ways for a ghost to raise their ranks, however,
in doing so, they become tied to an aspect of death, and are unable to move on.

Their kin

Their is more to speak of, but these will do nicely for the time...

Those that have made deals with the little gods of death for extended life, and now do their bidding...

Dread kings of the underworld, pray they never take intrest in the mortal world.
