The Adrassi elves are a large clan, exact numbers unknown but suspected to be in the low thousands, of mostly wood elves. Many of them live in smaller nomadic tribes. But there is at least one large city within the trees. Plus a few smaller settlements.
The Adrassi are primarily wood elves, but with a smattering of high elves, half elves and other races that have accepted their ways. The Adrassi have a habit of painting their faces or hands with some blue or purple dye, using curly lines and small circles to make up small patterns. Not all members follow this tradition but it has been a fashion for almost the last century. Many of the most common symbols have come to hold meaning that other Adrassi generally recognize. And can be used to express their current state of mind, their occupation, among many other things.

People do not know if the elves are named after the forest or the forest after the elves, but as far as humans know, the elves have always been here. The elves say their people move here from a distant forest many generations ago. Due to overcrowding, but the details are lost in the past.
The Adrassi consider the forest their ward, and although in the the past have allowed humans to log it, they believe it is time for the forest to rest and recover for a few decades. Their powerful allied among the druids of Adrassi agree, its a pity the short lived humans of Coin can't understand the need for this.
