What is the gist of that adventure hook?
[sblock]Ismark is engaged to be married to the daughter of the Boyar of Graenseskov (border woods), who is a hagspawn that was switched at birth.
The Boyar will expect Ismark to find and slay the Beast as part of his new responsibilities. The adventure assumes the party has met Ismark already and would feel obliged to help him. Considering the events of my own home game so far, it's a perfect set up for my PCs.[/sblock]
