Molten Mischief

From the Introduction: Molten Mischief is a standalone encounter designed for five adventurers of 3rd to 5th level. Settled on the edge of a forest with ties to the Feywild, the town of Yaviras has become accustomed to the harmless trickery of gnomes and faeries. But when a practical joke goes awry and a portal to the elemental chaos is created and fiery elementals begin to cross over, a living inferno threatens to consume the forest, town, and anything else in its path.
