Garth Agarwen is overrun by the servants of the Red-maid and Ivar the Blood-hand. Some of these servants are living entities corrupted by the horror wrought upon them by the fallen Men of Rhudaur, others are the Dead. Wights, animated through the dark sorcery of Ivar the Blood-hand, spread corruption to the land with every footfall. In the Arboretum, they befoul the earth and cause all within to suffer the pain of corruption.
Wights within the Arboretum continue to spread corruption to the flora and fauna in the area. To begin healing the land these foul creatures must be cut out of the world.
