The Far Harad Swampland can be found in two patches in western Far Harad: one around Lake Chunha at the southern end of the Harad Mountains; one further south, in the midst of the plains, in a gap in the Far Harad Jungle.
It is quite similar to other swamps of Middle-earth. There are no animals or NPCs here, and it contains many pools and patches of sand, clay, and quagmire. This swamp may be greener than, say, the Dead Marshes, but it can still be dangerous for the unwary traveller between quagmire and crocodiles. Be sure to take a shovel with you when visiting this land, and some good, crocodile-proof armour.
Uplands: A version of the swamp with fewer pools, higher land generation, and many more trees.
Lowlands: A variant of the swamp 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 the Far Harad swampland or any swamp biome.
There is nothing built in this swamp.
This swamp is uninhabited, except for hordes of crocodiles and the occasional vanilla animal.
As with every biome in Far Harad except Perdorogwaith, the Swampland generates gemstones at a slightly higher rate than most biomes, akin to the rates at which they can be found in most mountain foothills, together with all of the usual ores.
The Far Harad swampland is a semi-wooded marsh. It has greener grass and leaves than other marshes.
The Far Harad swampland contains numerous swamp oak trees (oak trees with vines growing on them), regular oak trees, and large, branched oaks that seem to spawn more commonly here than in other places.
