- Udûn is a depressed valley in The Plateau of Gorgoroth located in northwestern Mordor.
- Following Sauron's demise, the various forges, foundries weapon halls and smelteries constructed in the valley of Udûn have been left in shambles, with acid pools and waste left free to pour out onto the landscape. Foul orc villages and encampments clutter along the roads, as they prepared for the Host of the West. Slaves that survived the initial quakes and blast of One Ring's destruction still work away, not knowing the liberation that awaits them. Yet, many ancient curses and hidden evils still lie within the tall strongholds of Durthang and Anglach, waiting to pour out onto careless explorers seeking to pillage the once mighty war-machine.

Lore: Udûn (stronghold of Melkor)
Dates: Constructed in the beginning of the World, ruined c.4,000 years before the beginning of the First Age Location: The far north of the World Pronunciation: oo'doon Meaning: The Sindarin form of an originally Quenya name, probably meaning 'Underworld'
- Udûn was the Sindarin name of the fortress of the first Dark Lord in the far north of the World. It was the first and greatest of his citadels, delved in the earliest days, the home to hosts of demons and monsters. From Udûn, the Dark Lord troubled the world for millennia. From there, he drove the Valar out of their dwelling-place in Middle-earth, and into the West. At the time of the awakening of the Elves, though, the Valar attacked Udûn in full force, and destroyed it utterly, carrying its master back to Valinor as their prisoner.
- Udûn also appears as a name for the northern valley of Mordor that lay behind the Morannon. No doubt Sauron chose this name in memory of his ancient master's greatest stronghold
