This human-shaped beast has a horse’s skull for a head. It walks on cracked hooves and bears the rotting wings of a carrion bird. Deacons of the Horseman of Pestilence, leukoloths serve their lord in Abaddon as well as across the planes by spreading plagues and pandemics. The skulls that serve as their heads can be replaced with any skulls, yet these creatures choose horse skulls to show their loyalty to the Horsemen. The creature’s true head is merely a blistered knob between its shoulders.
A leukoloth can unleash a cloud of corpse-bloated, biting black flies in a 20-foot cone
Yugoloths (formerly known as daemons) are neutral evil natives of the lower planes of the Bleak Eternity of Gehenna and the Gray Waste of Hades.
While at first glance these creatures seem like enormous and foul bullywugs, their dangerous gait, dead eyes, and wicked claws give away their fiendish nature. In their home environment, hydroloths swim the sickening rivers and seas of Abaddon and the River Styx, ducking beneath the rivers of pus and bile only to leap out at enemies and rend their flesh with tooth and claw. It is said these are among the few creatures able to survive in the deadly waters of the River Styx. When called to the Material Plane, hydroloths serve powerful spellcasters, protecting domains dotted with pools, streams, and even sewer complexes. Associated with death by drowning, these fiends use a favored tactic to draw the most anguish from their victims. Hydroloths first attack with their inky black sleep spittle, hoping to render victims unconscious. With their opponents unable to fight back, hydroloths drag their enemies into the foul waters they call home and delight as the liquid fills their victims’ gasping lungs. If unable to drown a victim, they finish the job with jaws and claws.
Hydroloths possess an awkward gait, springing back on their heels and leaping about like humanoid frogs. Even so, they move in an unpredictable manner, twisting their bodies with each hopping movement. Hydroloths can also unfurl flaps of skin that allow them to glide through the air.
A shadow demon is a demon that looks like a gargoyle made up of darkness and shadow. Shadow demons do live with our demons in the Abyss but some do reside on the Plane of Shadow.
They desire little more than to feel the life they once had, and stalk and kill other living things for that purpose. While they serve Abaddon without question, they resent their position, and desire anything to be free of his control – although none have managed it yet.
Shadow demons do not normally hang around other demons but they will usually hide inside a solid object, and then pounce on their unsuspecting prey. It will often use deeper darkness to aid it in its fight.
Like other demons shadow demons speak Abyssal.
Some cults dedicated to Shar or Mask use shadow demons for spies or guardians.
This can be located from the largest portal hole from Pzunia. This layer is really nothing but a massive gash in the Abyss and creatures live within the canyon. Asima is the ruler of the layer.
The Grand Abyss is a deep crevasse without a bottom and without a top, thus it is also call the Bottomless Pit. If you do manged to climb out of the Grand Abyss, it is because you somehow stumbled upon a portal or gate which usually lead you to the Plains of Infinite Portals (or somewhere much worse). If you do fall in the Grand Abyss, it is possible you will fall forever…but usually a flying fiend will catch you somewhere along the way and make a meal out of you, or you smash into one of the many bridges and pathways that span the walls of the layer.
The Grand Abyss’ length is bridged by and surronded by paths built by demons and their slaves. Minor demon nobles often bully their slaves into digging and building fortifications along the walls of the endless crevasse. It is said that the layer itself eventually petrifies any mortals from the prime plane, as testified by the remains of shattered statuary found on many of the ledges along the walls.
No one demon prince can claim entire rulership over the Infinite Pit, but that does not mean none lives here. Somewhere deep down, can be found the realm of the demon prince Abaddon. The walls of the length of the layer that he claims as his own are lined with millions upon millions of locust demons. Somewhere further down the pit can also be found the realm of the apocalyptic dark god Nastrond.
Some claim that the Grand Abyss is not really endless, it is just one long deep, deep pit that eventually loop back upon itself. But so far no one is foolish enough to test out the theory.
