Bolstering Our Army

The spears and swords of Eataine were sent to bolster the ranks of those who venture to the Isle of the Dead, but they have been waylaid by a power that is older than the fabric that forms our world. In their travels, they stopped to drink of a well to the west. Unknowingly, they partook of water that had been corrupted by a foul servant of Chaos. Imprisoned they are in a nightmare of endless torment, and there they will stay until you free them. Go to the west. Slay the Beastman that maintains the ritual. Use this sacred talisman to purify the wellspring. Free my brothers so that they may fulfill their destinies by your side upon the Isle of the Dead.

Search for the Beastman Shaman west of the Well of Sar-Saroth. Halt his ritual upon the wellspring by taking his life, then use Onerian's Talisman to purify the waters and free the Silverhelms from Eataine. Speak to Imronel Greenwood when this has been finished.
