Fall the Stars, Rise the Dawn

Cat is a mark, a Visonian cursed to kill, and rumored to have powers associated with darkness itself. This makes them a powerful asset to many, and a threat as well.
Though a fugitive and presumably evil to the core, Cat doesn't feel such. Between confrontations with a strange entity, betrayal from those they held closest, and secrets lurking in every corner, Cat must decide if their strange powers are truly a curse... or a gift.
