Thorned Wood
The Thorned Wood is an incredibly dangerous forest. It was to here that the Illisyr were exiled in ages past.
The Thorned Wood always connects to the caldera containing the World Tree, and branches of it cross the world with unnatural vitality. Sections of it cut under mountains and cross the sea floor, accompanied by bubbles of air allowing it to be used as incredibly dangerous travel routes. Most branches of the Thorned Wood are no more than a dozen miles across, and they violently resist any attempt to clear them.
The trees in the Thorned Wood tend to be immense, with unique properties which can't be found anywhere else. Magic seems to pervade the forest, allowing creatures to grow larger and stronger much more quickly than normal, and adding strange mutations to them. Few communities can survive a single generation within any of the branches of the Thorned Wood.
