In the previous session the heroes had finished the second keep of elemental evil and killed its boss, a wereboar. This session began with the realization that the group paladin was now infected with lycanthropy. And being just below level 5 they didn’t have the necessary remove curse spell to get rid of that. So instead of directly heading for the next keep, they returned to Red Larch again, where the local priests were able to heal the paladin from his curse.
On leaving the temple the group witnessed an attack on the town by two ankheg. They were able to defend the town, but the burrowing monsters caused a sinkhole to appear in the middle of the town square. Exploring that the group found a small dungeon (the “Tomb of Moving Stones”) with a temple inhabited by a priest of the earth cultists. They killed the priest and discovered evidence that he tried to convert a group of town elders, the “believers”, from a harmless excuse to spend evenings among men to a far more sinister cult of elemental evil.
The Tomb of Moving Stones is normally a far lower level adventure, designed to get a level 1 group started in Red Larch. In this case I thought it would be a nice opportunity to introduce the earth cult a bit more, before the group heads into their keep. The added advantage was that the xp from that dungeon got the group to level 5, which is what the next dungeon is designed for. As level 5 is a major jump in power, I thought it was wiser to do it that way.
