Foul, ancient evil from The Rift of Nûrz Ghâshu has made its way to the surface of Angmar, including Khruthakh, who scouts these lands for a lost power.
'Khruthakh is most likely a Wight of sorts. This being may be under the control of Ulkharn or some other ancient evil dwelling in the depths of The Rift of Nûrz Ghâshu.
'This ancient armour, animated by the darkness of Nûrz Ghâshu searches for something. If we are looking for the same object, this creature should be dealt with soon! My research continues.'
Khruthakh can be found somewhere in Angmar.
You should defeat Khruthakh.
