Bonestalker

Bonestalkers are fey creatures that feed on fear and enjoy to hunt other creatures. Living in deep, dark forests and twilit swamps, they terrorise those who enter their territories as well as those who live on their outskirts. They collect the skulls of their victims, carrying them inside their wings as they draw power from these trophies.
