September came in with golden days and silver nights, and they rode at ease until they reached the Swanfleet river, and found the old ford, east of the falls where it went down suddenly into the lowlands.

The Return of The King, Many Partings

Swanfleet, also known as Nîn-in-Eilph, is a large swamp in the north-west of Middle-Earth. Swanfleet is found in-between Eriador, the Lone-Lands, Minhiriath, and Enedwaith. The Greyflood and Glanduin rivers flow through it, with many offshoot streams into the swamp. Swanfleet contains numerous swamp oak trees, with regular oak and birch trees sometimes generating as well. Upon entering Swanfleet you gain the achievement "Nîn-in-Eilph".

Swanfleet is somewhat more hospitable than the other marshlands, as it has greener grass and brighter skies than Nindalf, there are no wraiths in the water, as in the Dead Marshes, and there are no midges (Midgewater). There are, however, patches of quagmire, so you should carry a good shovel with you in case you fall in, or be very careful.

Variants Edit

  • Swanfleet Swamp Uplands: A version of the marshes with fewer pools, higher land generation, and many more trees.
  • Swanfleet Swamp Lowlands: A variant of the marshes that is more or less flat, and is more like a vast pool choked with bits of land and quagmire.

There is no standard version of Swanfleet or any swamp biome.

Structures Edit

Mobs Edit

Farm animals, boars, and a few other mobs spawn in these swamps.

Vegetation Edit

Swanfleet is a semi-wooded marsh. It has greener grass and leaves than other marshes.

Swanfleet contains numerous swamp oak trees (oak trees with vines growing on them), regular oak trees, some birch trees, and the large, branched oaks that seem to spawn more commonly here than in other places.

Berry bushes can also be found here.
