Strange earthquakes have been rocking the small town of Pimatsih in Sarkoris, and it seems to coincide with the arrival of Hesla Embersplitter and her newest acquisition: Riftcarver, the scythe that once wielded by Deskari, the demon lord who ripped open the Worldwound. As the PCs arrive to investigate and help secure the town, a demonic incursion begins, and they must work to help bring the Sarkorians together to keep the town and its inhabitants safe. However, lurking behind the horde, the Split Ember has made the Lord of Locusts walk again and he turns his hungry gaze and maw toward the Pathfinders.
