Sewer Bestiary
Beneath crowded cities, sewers connect with caverns, forgotten ruins, mines, cisterns, and secret tunnels. Players explore these neglected passages, where waste, disease, magic, contraband, and failed experiments have created dangerous creatures. They investigate what lies below the streets and deal with the threats that emerge from the darkness.
