In Durthang, strict order is maintained by guard captain Magtárb the Furious, head sorcerer Dâurazar Drear-star, and Khilnazt, his Uruk assassin.
The fastness of Durthang would hardly hold to its strict order without three of the Captain of the Pit's most trusted lieutenants: the guard captain Magtárb the Furious, head sorcerer Dâurazar Drear-star, and Khilnazt, his Uruk assassin. Gondor will face a far less formidable threat when assailing Durthang without these three.
Defeat Magtárb the Furious, Dâurazar Drear-star, and Khilnazt the Silencer in Durthang, in Udûn.
Defeated Ugrukhôr's three trusted lieutenants.
