Pertorogwaith

Pertorogwaith is a biome that is located on the east coast of Far Harad. This biome is the homeland of the Half-trolls.

Overall, Pertorogwaith's geographical features consist of dead trees, mostly Acacia and Oak, boulders, which are made of stone and hardened clay, scattered skulls, piles of Soul Sand, and living Acacia trees. Oak trees and piles of both cracked and ordinary Mordor Brick can be found, along with a special new shade of light gray water unique to Pertorogwaith. Lava pools also seem to spawn more often here. All of the islands surrounding Pertorogwaith are volcanic islands, along with other sections of central Perotorogwaith. It is similar to Tolfalas, except even more desolate, and is slightly reminiscent of the Rohan Uruk Highlands, except with Acacia trees.

Upon entering this biome you get the achievement "Monstrous things".

Mobs
Half-trolls, Half-troll Warriors, Half-troll Scavengers, and Half-troll Warlords live in the biome of Pertorogwaith. Besides the Half Trolls and Rhinos that only occasionally spawn ridden by Half Troll Warriors, squids are the only other mob from both vanilla Minecraft and the LOTR mod that spawn here. Half Troll structures also spawn here, including the Half Troll House and the Half Troll Warlord House.

Vegetation
Pertorogwaith mostly contains dead trees, but there are living Acacia and Oak trees here as well. Some patches of grass and dead trees are blasted or covered by boulders or piles of randomly spawned Soul Sand. Ground vegetation includes wheat grass, thistles, and clovers. Giant Baobab trees also spawn in the Forest Pertorogwaith biome variant.

Pertorogwaith Forest
The Pertorogwaith Forest biome variant includes more and more closely spaced vegetation of all kinds present in Pertorogwaith, particularly both living and dead Oak and Acacia trees. One special feature of the Pertorogwaith Forest variant is that it includes large Baobab trees, which do not spawn in the rest of Pertorogwaith. All Half Troll structures and Half Troll mobs spawn in this biome variant.

Pertorogwaith Oak Shrubland
The Pertorogwaith Oak Shrubland biome variant is home to a unique ground cover of one block tall jungle trees surrounded by Oak leaves that resemble shrubs. This biome variant seems to have only that one simple differentiation form normal Pertorogwaith and has all of its other normal features.

Pertorogwaith Dead Oak Forest
The Pertorogwaith Dead Oak Forest contains more dead Oak trees than other parts of Pertorogwaith, and more dead trees in general than the standard biome variant. It also includes all of the features of standard Pertorogwaith.
