Tomb of Horrors
The astral dominion of the god of the dead was once a dark realm of spirit armies and mortal souls held in torturous servitude. Though most of these condemned spirits have long since passed on, Pluton remains a deadly threat for those who walk its ruined ground. The ruins of Pluton are a seemingly endless series of wasted hills cut with broad stairways and terraces. Rubble of ice and rock is strewn amid a layer of ash across any open ground, and a gray haze shrouds the air. Gardens and groves were once plentiful here, but the spirit of life fled from this place long ago. Tight-growing stands of olive trees are twisted by blight and shadow, their dead fruit forever rotting but never falling. Forests of willow and poplar display dead leaves clinging to blackened branches, hissing in the ever-present wind. The greatest structure ever raised in Nerull‘s dominion was the Reaper’s fortress, Necromanteion.
In the aftermath of Nerull‘s death, most of the uncountable souls he had enslaved followed the Raven Queen to her new dominion in the Shadowfell. Thousands of spirit-creatures and many of the Reaper’s most foul servants remained behind, lingering in the darkness that was their masters’s legacy. Across the ruined dominion doomed souls still labor at tasks they cannot complete or engage in rites of pain and torture in the Reaper’s name.
