Keeping Them Honest

There is clearly much the fool elves of Malekith do not know, such as of the power of the Dark Lord. How long did they think that we would remain unaware of their assault upon Ulthuan? They must think that they can claim that great island and its spoils before we would even prepare to join the fight! They would deny the Changer of the Ways that which should be rightly his! I will not allow those treacherous mongrels to lay claim to the lands of Ulthuan unchecked. They may think to take it all in the name of Malekith. With your presence in their battles at the Plain of Bone, the only means by which they can do that is by your death.

Journey to the Blighted Isle and join the battles upon the Plains of Bone. Speak with Nistren Tyros, and let him know that the forces of Chaos join the assault.
