The heroes, having neutralized the enemy's new weapons, directly assault the Wildwood Lodge to oust the murderous tyrant. After rallying local allies and besieging living fortresses, they discover that their opponent has taken refuge in an unknown dimension: the Plane of Wood. The heroes will pursue the enemy, reaching an elemental city that is all too familiar with the traps of the Wildwood Lodge. They must earn the trust of the inhabitants and explore the enemy's latest move before following into a ravaged wasteland and preventing an invasion that could devastate the Verduran Forest.
