Dark Woods

The toughest to get trough part of the forest. Most dangerous forest creatures are living here, and the low amount of light and rare difference in the terrain can make anyone who will not careful get lost in them. This already creates a natural barrier for the other parts of the forest and shields it from the unwanted visitors. But with it, there are a lot of necromancers and voodoo BFBs are settled here for the forbidden magic practices, releasing some magic into the wild in the process. This made some parts be even more dangerous, since wild magic that interacts with wilderness makes it alive and hostile to strangers. Druids and shamans can tame it, but not the outsiders who want to cross the forest.
