Bagud-dum has become the main stronghold of the Cult of Drugoth in the Welkin-lofts. It is imperative that their numbers be lessened.
'The Angmarim forces in the Welkin-lofts seem to be headquartered here, and not yet fully aware of our presence this high up the mountain. This is a golden opportunity for us! If we can thin their numbers now, while we have the element of surprise, we might deal a significant blow to the Cult of Drugoth. Oh, and keep your eyes peeled for those fell spirits they've been summoning up here. Those are just as dangerous as the Men who are summoning them, if you can believe it.'
Angmarim of the Cult of Drugoth and the fell spirits they have summoned can be found in Bagud-dum.
You should defeat Angmarim and fell spirits in Bagud-dum.
Hórin can be found outside the dwarf-fort Bagud-dum.
You should talk to Hórin.
