The ancient dwarf-fort known as Bagud-dum has been taken over by the Angmarim. There they plan to perform an ancient ritual which might reveal their true motives.
'This must be where most of the Angmarim travelled. This is a large camp! No sign of Loknashra out here, though... she must be inside. I do not know what horrors the Angmarim have waiting for us inside, but we have to find that staff before they complete whatever evil ritual they mean to do within! We must sneak inside, and quickly!'
Hórin is standing by outside Bagud-dum.
You should speak to Hórin and complete 'Instance: The Secret Ritual'.
The Angmarim cultists have taken over the dwarf-fort Bagud-dum.
You should complete objectives in Bagud-dum to prevent their plans from reaching fruition.
