Koltira, aboard Orgrim's Hammer, wants you to slay Alumeth the Ascended at Aldur'thar.
These fools have actually stumbled upon something that could pose a serious threat to our plans!
The leader of this particular sect, Alumeth, has ritualistically sacrificed himself and now his underlings are channeling power to his soul.
If he's allowed to rest, their efforts will soon transform him into a mighty adversary.
Combine his heart, skull, scepter and robes from around their chamber and use his remains on the crystal there.
Hurry, <race>! Destroy him before he becomes any more powerful!
