We'll need a fragment o' the core tae repair the Black Anvil an' who knows how much dark iron tae achieve the necessary purity. Thaelin can figure that part out.
In fact, I think he oughta go with ye tae get yerself a Fragment o' the Molten Core.
It's too dangerous tae go deep via mole machine, but he's got a hardy tank that can get ye the rest o' the way from the top.
Talk tae me when yer ready.
