The Pathfinders travel to Iobaria, where elven druids and centaur warriors are united against an unlikely threat: a self-propogating horde of corrupted leshys! The source of the Abyssal corruption may be tied to a previous trip to Iobaria by the Pathfinder Society, so it falls to the PCs to seek out the source of the leshy incursion and restore balance to the woodlands.
