The Underworld

The Underworld is a vast dimension of fire and stone which sits parallel to our dimension. Its chief purpose is to act as a processing plant for souls, recycling and retiring where it sees fit. Very few mortals live in the underworld, with the exception of its native races: the Demons and Flayers. Even then, the Underworld is an inhospitable place even for its own denizens, with small Pygmy Flayer villages serving as the only real places of safety in the dimension.

The grand exception, however, is the mysterious Castle Grim which is thought to sit in the center of the Underworld. Spanning hundreds of miles, this labyrinthine complex acts as the Underworld's central seat of power. It is here that decisions regarding the fates of souls are made. Not only do the Underworld's Soul Wells communicate directly with Castle Grim, but the complex also houses the largest known soul prison in existence, with an estimated trillions of souls deemed too corrupt to safely handle waiting in cells for future advances in knowledge to restore them to a workable state. Because of the dangerous nature of these souls, the prison and by extension Castle Grim are sealed off from the rest of the Underworld and can only be accessed by those within a small circle of the ruling class. Reapers are the exception, with each planet's reaper having access to a small section of Castle Grim known as the Scythe's Wing.
