The Glory of Ulthuan

Those twisted creatures seek to destroy our wellsprings! This cannot be allowed to happen, |n! This dark poison would seep into the very rock of the land, forever condemning it to a fate of death and decay. I need you to journey into the woods here and gather the herbs needed to counteract the vile toxins brewed by these dreadful servants of death. Bless these sacred herbs at an altar found in the Rushing Meadow. I shall teach you the blessing now.

Search Reaver's Mark to gather the herbs you need. Wildbrush can be found throughout the area. Starwillow Root and Valeflower can be found in the Rushing Meadow to the south. Use Melaina's altar in the Rushing Meadow to bless these herbs.
