Nathan Timothy
From Multiversal Omnipedia
Nathan Timothy was an ex-Darklord of the Core domain of Arkandale. He was a werewolf boat captain and merchant who traveled the Musarde River, plying his trades and occasionally preying (quietly) on some of his passengers. His son, Alfred Timothy, resented him for pretending to be human more than a wolf, and left him, eventually forming the domain of Verbrek. Timothy's curse was that he was trapped on his riverboat, unable to remain on land for more than an instant without experiencing great pain.
After the Grand Conjunction, Arkandale was absorbed into Verbrek, but Timothy remained trapped and cursed, although he could now travel any river in Ravenloft.
