The Gray Coven

From the introduction: Holmford is saved but the nightmare is far from over. Defeat has stoked the Coven’s rage and set them on the trail of those who dared foil their plans. The heroes must now take the fight to the hags before dark forces turn the hunters into the hunted. Deep in the Blightmoor, the Tree of Decay, home to the Gray Coven, awaits.
