BILDRATH CANTEMIR

Perhaps shaped by the miserable existence in which he finds himself, Bildrath is not a pleasant man. He wants only to make profit and offers no help or sanctuary to those in need.
He is the owner of BILDRATH'S MERCANTILE, the only functioning trade-post in the VILLAGE OF BAROVIA and he makes the most of his monopoly. He has a wide range of goods available. He can sell anything valued up to 25gp from the Adventuring Gear section in the PHB, although he sells items at 10 times the price given in that table.

He sees no need to bargain, as he has no competition in the village, claiming, "If you want it badly enough, you'll pay for it."
Anyone who tries to intimidate him will be introduced to PARRIWIMPLE, his musclebound, but devoted, nephew. Parriwimple is a simple but very strong man, as anyone who meets and sees him can testify.
