Brain-Storming: Monstrous dwellers of the abyss

Kytons are LE spirits native to Baator.

Mendicant: a member of any of several orders of friars that originally forbade ownership of property, subsisting mostly on alms.

The shadows parted to reveal a slowly walking man, a moth-eaten cloak and robe draping his figure, his hands clasped in prayer. The warriors made to move out ofhis way, only to find he had opened his arms...
and six skeletal arms began pulling the fighters into his cloak.

In many of the large cities of the Abyss, figures can occasionally be seen wrapped tightly in cloaks, large beards concealing their faces, and their eyes covered in a bandage. These are the Mendicants. The facial features don't appear to synch up with the actions of the face: the lips hang slack when smiling, the musculature slightly at odds. Beneath the bandage are lidless, limpid orbs with a red iris. When unclasped, the hands are revealed to have a razor-sharp, rigid bone spur along the pinky finger and edge of the hand. Further, from the depths of the Mendicant's sleeves appear skeletal arms - not from the shoulder joint, but as if disembodied - and bits of flesh slough off. The Mendicants rarely keep belongings other than these arms. And the faces, which are torn from still living bodies. Then the Mendicants open their mouths to reveal a tongue made up several thousand acidic filaments which strip flesh from the shoulderjoints of their victims. Once the arms have been torn from the body, they are concealed in the depths of the cloak and added to the collection.

Mendicants are most commonly priests and rogues, and are frequently summoned to the prime as assassins. In Graz'zt's court, a Mendicant with fighter levels acts as a body guard, his armored form and six arms gripping a variety of weapons.

Mardraum: When some strong minds die, they try to take others with them

The robed human seemed to appear out of nowhere. As the party stared in astonishment, his withered hands drew back a travel-stained hood. Revealed was something beyond words, a personal horror dragged from the depths of each victim's subconscious mind. They began to scream...

Those who die in their sleep normally pass on to their fate as petitioners, just like any other poor sod who ends up in the dead book. When particularly strong minds are snuffed out in the madness of absolute nightmare or pain, however, the psychic shock can sometimes give rise to these undead horrors. From a distance most mardraums appear roughly as they did in life. A cloak or hat normally shadows their face, and a breeze always seems to blow around them carrying the cloying stench of decay.

Wandering alone through ruined cities and other remnants of civilization, a mardraum normally remains invisible until it detects nearby life. Then it will approach its prey, becoming visible and revealing its face only at close range; where as many mortals as possible can see its horrible visage. Most that gaze into the face of a mardraum see one of their own nightmares gazing back, and are immediately struck with fright. The true horror comes later, however. Whether the spirit flees or is killed, those that survive an encounter find it impossible to sleep without seeing that same face revealed over and over again in otherwise normal dreams. Most mortals feel their sanity slipping away, and will eventually descend into a state of permanent catatonia. Bloods with a strong mind who resist the nightmares for three days in a row, however, conquer their fear and are no longer haunted by the fiend.
