The Champion of Minas Angos

Lindir translated the text you found from the Black Speech into Westron.

Description
Stage 1
Stage 2

'The text you recovered spoke of the betrayal of the Longbeards by the Dourhands, and of a champion that survived the death of his master, the pale dwarf called Skorgrím.

'I remember this dark day but is this evil champion the stuff of legend? That I cannot say, but this Mordirith's servants are many and powerful...I do not doubt these claims.

'You should investigate the matter. Return to Minas Angos and strike its gates. Should this fabled champion exist, he would be ill-advised to ignore such a challenge.'

Minas Angos stands on the western side of Barad Gularan, south of Gath Forthnír.

You must travel to Barad Gularan and issue a challenge to the evil dwarves within Minas Angos.
