'This land was corrupted by the war which raged here. Blood, much blood, spilled into the springs of the Lady, until all became red, and the springs became a swamp. The Lady, whose name is not remembered, became the Red-maid, a creature lost and corrupt. Ivar the blood-hand came not long ago and awakened her again and claimed power over her. Now Ivar is a greater threat than ever he was.
'Thou must strike against him to restore the balance betwixt Man and Nature. Until the Red-maid be redeemed or destroyed, my brethren and I are doomed to this wretched state.
'The west is where thou must travel to destroy the wight-lord Brudhraw and his soldiers. They serve the Blood-hand and must be destroyed.'
Emelin told you about his failure to protect one of the River-maidens and the curse it brought down upon him and his men. He agreed to help you if you accomplish a task for him.
Emelin told you that the Gaunt-lord Ivar the Blood-hand raises the wights as his soldiers. You must destroy them and their lord, a wight called Brudhraw.
You defeated the wight-lord Brudhraw. Now you should return to the shade called Emelin.
Brudhraw is around 37.8S, 29.6W
