Now that you have acquired the Light of Eärendil, Mithrandir has asked you to press further into Mordor.
'Adventurers of the Free Peoples have set foot into Udûn, but the fortress of Carach Angren has hindered further passage. The eruption of Orodruin melted the doors of the Isenmouthe and they cannot be shut, but enemies still hold the channel between Udûn and Dor Amarth.
'Some few have managed the passage: Rangers, Elves, and others utilizing the arts of stealth. I believe that you can advance into the Doomfold of Dor Amarth. Pass through the guarded Isenmouthe and find Brungos on the other side. He will tell you somewhat of what he has done, and what has yet to be accomplished.'
The Isenmouthe is the gate between Udûn and Dor Amarth, and it is built into the fortress of Carach Angren.
Brungos is on the other side of the Isenmouthe, in Dor Amarth.
Fierce enemies stalk the Doomfold of Dor Amarth, and Brungos asked for your help defeating them.
