Highland Forest

The Highland Forest in the Twilight Highlands is the big green area south of the Devouring Breach, surrounding the northern border of the Obsidian Forest, and located west of the Twilight Shore.

• When looking at the fully unlocked map, though the Highland Forest is required to get the achievement Explore Twilight Highlands, it does not show the actual name of it, which is why players commonly have trouble finding the forest.

Since it borders the Obsidian Forest, it presumably is a part of that same forest that survived the petrification.
