An Episodic Life
The depths of this evergreen forest are said to contain portals to the Feywild and The World Tree. Its inhabitants seem to be hostile to strangers though, and sometimes send forth shambling mounds and other animated vegetation to wreak destruction for unknown purposes.
Some time ago an elven family known as the Dawnstokes emerged from the wood (and presumably the Feywild or another plane), and set up a trading post on it’s outskirts. They deal with Chasm and other settlements, trading wood, herbal components, potions, and so on in exchange for metals and arcane components.
There are rumours of a goblin kingdom somewhere within the bounds of the wood as well.
