Swanfleet

Also known as Nin-in-Eliph, the Swanfeet biome is a large swamp in the north-west of Middle-Earth. Swanfleet spawns at the meeting of Eriador, the Lone-Lands, Minhiriath, and Enedwaith. The Glanduin river flows through it, with many offshoot streams into the swamp. No Orcs - or anyhting else - spawn here. Swanfleet contains numerous swamp oak trees, with regular oak and birch trees generating as well. Upon entering Swanfleet you gain the achievement "Nin-in-Eliph."

Swanfleet is comparatively nicer 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), orcs, or any NPCs.

Mobs
No Orcs, hostiles, or NPCs spawn here. Some farm animals still live here, though.

Vegetation
Swanfleet is a semi-wooded marsh. It has greener grass and leaves than other marshes. Swanfleet contains numerous swamp oaks (oakes with vines,) some birch trees and regular oaks, and the large, branched oaks seem to spawn more commonly here than in other places.
