But the Isle of Tolfalas was almost destroyed, and was left at last like a barren and lonely mountain in the water not far from the issue of the [Anduin] River.

Tolfalas is an island located off the coast of Gondor. It is independent from Gondor and is its own biome.
Tolfalas is a desolate island, containing dead trees, rocky hills, and small mountains. Large swaths of the island are barren and hilly, making most of the island unsuitable for large-scale settlement. Once, it may have been inhabited by the Men of Gondor, as evidenced by the ruins that can be found here, but now it is ruled by the Corsairs of Umbar. Tolfalas is surrounded with beaches, which serve as a buffer between the biome and the Bay of Belfalas.
Once, Tolfalas was inhabited by Númenóreans, but the Drowning of Númenor destroyed and desolated the island. Now, it's little more than a staging area for Southron fleets.
Once the player enters Tolfalas, they earn the achievement "The Isle in the Bay".
Mountain - A mountain that rises from the surrounding terrain.
Dead Forest - A version of the biome forested with dead trees.
Dead oak forest - A version of this biome forested with dead oak trees.
Tolfalas is dotted with camps belonging to the Corsairs of Umbar, who use the island as a staging ground for assaults on Gondor. The island is also dotted with scattered Gondorian ruins, evidence of a time when Gondor ruled the island.
Ruined Gondor Tower - Ruined three-floored towers with battlements at the top. Its lowest level contains a Gondorian crafting table, a Lebethron casket (which may be empty or could contain loot), and a ladder; its second level can feature a straw bed, a barrel, and an anvil, though any of these can be missing; the top level, which features battlements, is always featureless.
Corsair Hideout - Larger bases hidden in the cliffs of the Coasts. Accessed by a hidden set of stairs, hideouts are battlemented, paved courtyards of Umbar Brick, which houses a fire pit with treasure piles, hanging pieces of Corsair Equipment, a hanging cage with Slaves of Harad, and a small open tent with a loot chest, a forge, and other useful equipment. A small group of Corsairs spawns here, as well as either a Slaver or a Captain.
Aside from bandits, the normal temperate common animals may be found in Tolfalas, as well as marauding Corsairs.
Slave of Harad - Slaves taken from among the victims of the Corsairs, most notably Gondorians, western Morwaith, and Taurethrim. They are useful as farmhands, and can be bought to plant and harvest whatever seeds you give them.
Corsair Slaver - Corsairs who manage the slaves taken in raids, and sell them to the highest bidder. They carry Branding Irons and wear Corsair Armour.
Corsair Captain - These foul men are the leaders of Corsair bands, most most vicious and bloodthirsty of the pirates of Umbar. They allow players with sufficient alignment to hire their Corsairs.
The grass on the island of Tolfalas is a sullen shade of green, rather like that of the Barrow-downs. The trees here are all dead, though they still provide a plentiful source of oak wood.
