Lithlad

Lithlad was an ashen plain of Mordor, south of the Ered Lithui and east of the plateau of Gorgoroth.
It is said that Númenóreans once had dominion over Lithlad during the Second Age, populated as a remote part of their empire. Being one of many distant locations they visited, many lost artifacts and ancient ruins remained there from this time.
The region is described in the game to have become ideal for dry-land farming due to long ages of continuous fallout from Mount Doom, which enriched the region with large amounts of ash.
