Helfire Mountain

A doomsday cult has opened a portal inside a volcanic mountain, allowing an elemental lord to enter the realm. A party of 4–6 adventurers of levels 7–9 must reach the heavily guarded portal and attempt to send the entity back. This mini-dungeon can be added to an existing campaign as a side quest or played as a short standalone adventure.
