Bartleby is the potion merchant in the Town of Grove. He sells other items as well, such as Fishing Poles and Town Portal Scrolls. In Fate, the character starts out beside him. There is a man named Beregor on the other side of town just to the south, that looks exactly like Bartleby. It is useful to buy some potions from him before setting off on your adventure because health potions can save you from dying.
