In the Sixteenth Hall, defilers and other Orcs, sworn to some dark power, poison their brethren with a fungal disease. The source of this evil lies far beneath the surface of their stronghold, once inhabited by the dwarves. The Dwarves n Moria wish only to drive the Orcs and the evil of the Sixteenth Hall away from their former realm.
The Lost One is below the Sixteenth Hall, south-east of the Twenty-first Hall.
You have been challenged to prove your great worth by defeating the Lost One without making the battle easier by killing his summoned gredbyg.
