Soulless who fail to pass the Soul Fasting ritual converts into cursed demons with the wings of a bat. Sent all over Rotvar, these flying creatures hid in the shadows of the night; their beauty bewitches even the strongest spirits, devouring their souls and draining every drop of blood from the unfortunate. After awakening from a centennial sleep, Akela, the first of her cursed species, is driven by an insatiable thirst for souls and blood.
