Franklin, a monstrous giant snail and a professor of potion-making, has been indiscriminately disposing of potions, which have been draining into the local water supply. An unforeseen byproduct of this was the incidental awakening of giant rats that were drinking from the tainted water supply. The awakened rats have taken over the undercroft where Franklin stores his treasure and old supplies for potion-making.
