Manngeier

Covered in shiny black feathers the color of oil, possessing a hooked beak and bright pink sclera, bearing a set of grand and terrible wings on their back, and brandishing three-fingered hands ending in talons, the Manngeier's meanacing appearance causes fear in most creatures with functioning eyes. Sometimes refered to as "foul guardians" they serve as extremely effective protectors of heros and similarly important peoples.
Manngeiers are born of a child's fear of the dark, and exist to torment future legendary figures and stop them from achieving their destinies. However, due to the intervention of the trickester god L'mau, the goals of their progenitor god, Nachtpirscher, were subverted, and their intentions twisted into the inverse. Manngeiers, instead of wanting to torment and consume their host, now wish for their host to be safe and healthy.
