The river Lhûn flows in the eastern part of Ered Luin past the areas of Haudh Lin and Kheledûl, through Falathlorn, and past Celondim before it flows on to Mithlond and the sea. At Kheledûl friendly dwarves used run the docks, as do the elves in Celondim. Just below Duillond, at a high bridge across the Lhûn the Eastway runs from Thorin's Hall to Needlehole, in the Shire. The river is known as Lune to hobbits and men.
- The river Lhûn was a river of north-western Eriador.
- In the Second and Third Age, it emptied into the Gulf of Lune that broke through the Ered Luin and thence into Belegaer.
- It had four tributaries: the Little Lune and one unnamed one arising in the Ered Luin, another unnamed one beginning in the Hills of Evendim north of the later capital of Arnor, Annúminas, and the fourth running through the western part of Yondershire. It was not connected to Lake Nenuial, the origin of the Baranduin (Brandywine) river.
- In the First Age, the course of the river is not known. The Gulf of Lune was not created until the War of Wrath so the river must have had a different lower course. Possibly it connected with the Baranduin further south.
Course of the River
- This river begins its stream in the western reaches of Forochel [10.8N, 86.2W]
- The Lhûn exits the map south of Celondim [29.20S, 92.3W]
The Lhûn flows down from the Northern Ered Luin in northwestern Forochel, close to the 7th Dwarf Channel.
The Lhûn then passes the Icereave Mines, not far to the west of the dwarven fortification of Zigilgund.
The tundra landscape stretches out before it as the river turns down the gorge past Norsu-hauta.
The Gauredain prowl the river's upper reaches, and wildlife drink its clear waters.
The island of Kissa-sari splits the stream in two, the fresh water able to keep stands of fir trees alive despite the bitter cold.
Beyond the island and its stalking saber-tooths, the Lhûn rejoins itself and keeps flowing.
After another drop and a bend, the river flows off to the south and away from Forochel, crossing vast stretches of tundra and mountain valleys.
Far to the south, in Ered Luin, the river emerges again from its long journey on its very last stretch.
The river here forms a border between Haudh Lin on the west bank, and the Yondershire on the east.
The fortress of Lhúngobel, named after the river, sits on a high ridge above the water.
The Lhûn then passes into Falathlorn, the Elven realm that sees the river on its last journey to the sea.
Here, the Lhûn's only crossing stands astride the river, an important bridge that connects all the western realms to the rest of Eriador.
The elven city of Duillond lies high above the river, offering splendid views in three directions.
Across the Lhûn lie the Falathlorn Homesteads nestled scenically in the cliffs.
Flowing past the haven of Celondim, the river starts to widen as it nears the Gulf of Lhûn.
The river leaves Ered Luin behind and proceeds to the Grey Havens where it feeds into the ocean.
