Found lurking in a rat warren off Old Aena’s cellar, Boris appeared to be in the early stages of lycanthropy and stuck in hybrid rat form. He’d tried to buy a cure from Aena but couldn’t afford the 200 crowns so broke in to try to find it himself. He failed in that, her cellar being something of a mess, but did find a book on lycanthropy, which he duly ‘borrowed’, and the rat warren, which he adopted as a hideout.
Boris explained his situation and Glimble took pity of a sort on him, strong-arming Old Aena into handing over a potion to cure him. After an uncomfortable night, Boris found himself once more human.
