Oak is moderately sized village in the barony of Strohmburg, within the Grand Duchy of New Newportton. It’s most notable feature is the hospital, which provides free care to anyone able to reach it and sends volunteer clerics and chirurgeons to nearby settlements that require them.
Unknown to many, the hospital was established to placate a vampire spreading a magically-resistant form of cholera among the villagers. In life, the man and a young girl he had been caring for had fled a nearby village suffering from a cholera outbreak, not realizing they had already been infected. They were both gravely ill by the time they reached Oak, and the villagers turned them away for fear of the disease, hurling stones to drive them out. Both victims died before reaching another town. Driven by vengeance, the man rose as a vampire and terrorized the villagers; the girl became a ghost, and attempted to warn a party of adventurers of his actions. The girl’s spirit found rest when the adventurers learned the truth; the vampire was willingly laid to rest when they promised to establish the hospital so that their tragedy would not be repeated.
