Nobody knows but a few of his kind were spotted hundreds of years ago.
Even he is un-aware of exactly what he is, but knows he is the last of his kind. Named after the urban 'myth'. Described to have un-usually sharp nails, (described as claws,) and the ability to run sideways and make incredible leaps across buildings. Par core! As far as I know he has no magic. He IS a magical being, Dusk, so he essentially doesn't ...harness magic like an Elemental or Adept.. Though he can run sideways he is not like Tanith Low. A psychopathic 'need' to murder. He was once tricked by Tanith Low into a confined place after running to a baby to, typically, kill it. TO KILL A BABY. He was beheaded by Evil Tanith Low.
