The Bottom of the World
Vayne Hall was one of the One Hundred Heroes. As the story goes he was in love with Casandra Bless. In order to enlist the aid of Shading, the God of Gambling, he vowed to kill Casandra if he lost a hand of cards against the God. Hall won and Shading aided him against The Great Evil.
The adventurers suspect that this Vayne Hall may be some how related, or be the same person, as the card player, Vayne Hall.
