Sauron has been defeated, but the shroud over Gorgoroth must be pierced if the Free Peoples of Middle-earth are to be made safe of the evils the Dark Lord set in motion before his fall.
'Sauron has been defeated, but that is not the end of the evil he stirred into wakefulness, ${PLAYER}. Who can say what lies hidden beneath the shroud that covers Gorgoroth, beyond the wreckage of the Black Gate? The Dark Lord was a master of foul sorceries, and from the height of Barad-dûr he set many terrible plans into motion. I cannot believe that every one ended when he did.
'Adventurers have already begun taking hesitant steps through the ruin of the Gate. Let us join them, and I will take their measure. The dangers that await in Mordor will be too great for some of them, I warrant.'
Mithrandir asked to meet you just inside the ruin of the Black Gate, there to take the measure of the adventurers that desire to press forward into the land of Mordor.
Adventurers have passed through the ruins of the Black Gate into Cirith Gorgor, and intend to seek treasure and glory in Mordor. Mithrandir asked you to speak to them and warn them against taking brash action.
Dangerous foes stalk the vale of Udûn, and Mithrandir asked you to venture forth with caution and defeat them.
The forges of Mornaur are on the western side of the vale of Udûn.
Rhogrin asked you to push over some of the anvils at Mornaur, rendering them difficult for the Orcs to use.
From the cliff's edge below Mornaur, Rhogrin saw a large group of Orcs and trolls in the basin of the vale north-east of Durthang, and asked you to investigate in order to make the area safe for other soldiers of Gondor.
