a half-vampyre, half-ghost of the chaos storm
Once a man, Tristen was cursed by a long-ago evil deed to be a blood-drinking monster during the day, and a vengeful ghost during the night.
Unbeknownst to Tristen, his possession of a piece of the Rod of 7 Parts kept the Chaos Storm from destroying his land. When the Revengers left his castle with the rod. the storm closed in and wiped out his kingdom.
But not even the Chaos Storm could release him from his centuries of torment. Tristen still wanders the storm, a wrathful spirit who can never be forgiven for his crimes.
