Shadow demon

Shadow demons, also called shadow fiends, were the product of a demon whose essence could not properly reform in the Abyss. Trapped within the form of a living silhouette, these demons were merely shadows of their former selves.

Description
The physical form of a shadow demon was normally vague and undefined as it was often confused with the dark contours of the environment or the shadows of onlookers. Although they resembled wraiths or shadows they were in fact entirely different creatures. By shining a light source on shadow demons one could resolve the nearby darkness to reveal their distinct shape. The true form of a shadow demon was that of an angular and macilent humanoid figure with a pair of bat-like wings, inky talons and a lower half that bled away into nothingness.

Personality
In terms of active behavior, shadow demons were very similar to devils in that they had interest in corrupting mortals and tempting them towards evil. They also reveled in capturing souls as they could be used as currency when dealing with other beings of the Lower Planes like night hags. The key difference between devils and shadow demons was their end goal. Shadow demons were like the undead in that their aim was the complete obliteration of all mortal life, and unlike the devils did not acquire souls in a bid for power and status.

Abilities
Being the shady figures they were shadow demons preferred to lurk within the darkness where they were practically invisible and some were known to be able to create it themselves. They flickered throughout the shadows with supernatural speed, nimbly gliding without a sound while stalking their targets. Ghastly claws tore away not only the flesh but the fabric of the mind, allowing them to consume a targets nightmares, fears, memories, and other negative mental aspects. Being incorporeal, they could phase through walls and other mundane barriers with ease and struck their targets when and where they least expected them to appear. Their forms were unaffected by mortal ailments, severe temperature, fatigue and were generally hard to injure by all but magic. Fortunately their weakness laid in their predictable aversion to light, as without darkness to hide in, their true forms were exposed and vulnerable.

Society
Shadow demons were unique among the abyssal creatures in that they existed outside its conventional hierarchical structure, as they were not created like most demons. Unlike most current demons they were not tanar'ri either and so occupied no place in their personal system. Shadow demons normally worked under the employ of more powerful agents of evil as spies, assassins, scouts, advisers, and assistants. These beings included evil dragons, wicked mortal rulers, influential demonologists, demon lords, nightwalkers, and other dark powers who the shadow demons served well and effectively. They prompted these beings towards acts of great and destructive evil, especially the killing of evil mortals, and took their masters' souls when they died whenever possible. Souls were recognized as having value to shadow demons who traded them with greater demons and other inhabitants of the Lower Planes. They rarely interacted with creatures of equal strength to themselves like tanar'ri or other demons, only doing so when working towards a common goal or when asked to by their masters. Such beings were usually related to darkness and death such as the undead, shadar-kai or the dark servants of their current master. They were also known to cooperate with the deathpriests of Orcus.

Ecology
When a demon's body is destroyed on the Material Plane they are often either cast back into the Abyss, eternally destroyed, or reincarnated. However, sometimes when a demon is destroyed its demonic essence is released back into the Abyss but for whatever reason is incapable of reforming. This pure, unfiltered evil is channeled back into the Abyss and given an insubstantial physical form, birthing the nightmare inducing shadow demons.

Locations
Shadow demons were found in the Abyss. They abounded in the Darkflame neighborhood of Zelatar.

History
In 1485–1486 DR, shadow demons were among the demons that walked the streets of Menzoberranzan and were later sent to aid in the (failed) defense of Q'Xorlarrin against the dwarves.
