The Ash-Webbed Vault

Deep within the crumbling remains of the ancient ruins, the party uncovers a nesting ground where common vermin were overseen by a creature of supernatural flame. The floor is littered with the bones of previous victims, while the walls are draped in thick webbing that smells of brimstone and ozone. Searching through the refuse and the remains of the defeated monsters reveals a collection of oddities and lost treasures preserved by the dry, stagnant air of the vault.
