Demon form

Shadow demons, also called shadow fiends,[4] 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.[5] 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.[5] Although they resembled wraiths or shadows they were in fact entirely different…

A shadowed figure shrouded in swirling black mist, eyes glowing an eerie red, performs a ritualistic dance. A ghostly apparition rises from the ground, its form flickering and distorted, reaching out with skeletal fingers. The air crackles with arcane energy, casting long, ominous shadows on the desolate landscape.
