The castle that is on the edge of town was the lair of a Vampire Lord. The vampire was reportedly destroyed, but …
No other reason at this point to investigate it other than it is there and it is a creepy old castle. Also Jerry Beard seems interested in the fate of the former inhabitant.

Update: Need to investigate the castle to talk to Marrik Fordham.

Update: We visited the castle but was unable to find Marrik Fordham. It turns out the castle is once again occupied. This current owner is Ravenna, but she has become a vampire.

Update: Visited again. Broke Marrik Fordham out after a very tough fight.
