The Thorium Brotherhood doesn't maintain a militia - just a few guards, and me, and that's it. If we're to successfully strike against the Dark Irons of the gorge, we're gonna need help.
Mountain-Lord Rendan sits atop the tower across the gorge, to the south. He doesn't consort with the Twilight folks or fire elementals, but he hasn't joined the brotherhood either. Maybe it's time we paid him a visit. With his help, we might just stand a chance.
And who might you be?
Ah, an emissary from the Thorium Brotherhood. They're looking for my support? Fine, I might be willin' to help out...
...for a price.
Exit Thorium Point and circle around the Cauldron heading toward Blackrock Mountain. Take a left, to the east, and head up the hill to reach the top of Iron Summit.
