There are 2 Forests, both of which have been referenced in this discussion.
1 - Heartwood - Dryads, Stone Elves, and Hope/Despair
----- Stone Elves have a profecy that what's at the center of the forest will destroy them. They enslave? MWEs making them hallow elves to help fight the dryads? Despair was found in the center of the forest, Hope is now in the center.
2 - Chaos tainted forest - Dryads, Elves, Hedge witch, tree spirit
----- The Hedge witch created a ritual to heal the forest. We have gathered the components. Gwen has everything except the tree spirit (in Grey) and the heart of the forest. We need to escort her through the chaos tainted forest to get to the heart so she may cast the ritual.
