Black Swallow

Black Swallow is a Wraith - a species of ethereal being tasked with killing the chosen and taking them to the Nether Realm. The Wraiths are bound by three rules: to only kill the chosen, to only use enchanted weaponry, and never to intervene in the killing of a chosen, be it by fighting another Wraith or refusing the order to kill. Wielding an enchanted axe and known for killing without remorse or emotion, the once-human being now has no memory of his past. Until one day, a chosen human notices the invisible creature, and suddenly he begins to question his role and the strange rules forced upon the Wraiths by their leader - The Grandmaster.
