Undercity

The Undercity is a vast networks of bunkers, sewers and dungeons that lies beneath Avon Grove High School. It was first constructed in the mid 60's as a cold-war bunker but was sealed off when "The Beast" moved into the bunker system, created a den and made it unsafe for humans to inhabit. The old entrances are tightly sealed and unquestionably dangerous to explore. It is now home to the centipede nest, the dungeon of the Beast, swarm rodents, necrotic oozes, roaches and reanimated dead.
