World's Largest Dungeon
Fiendish Rat Swarms
Voracious eating machines, these swarms of fiendish rats roam the region, picking clean the bones of slain creatures, eating offal and garbage, and, when offered the chance, taking down fresh game.
Until recently, these rats were sealed in a portal in the chapel. Once Longtail released them, they spread throughout the region like a plague. They are resistant to flame and cold, as well as simple spells.
