Contrary to popular belief, White Bone Castle, the seat of government in Ravenwood, wasn't situated above the World Tree. No, this castle was built with bricks and metal, a structure unlike any traditional Forest Elf treehouse. It had the appearance of an ancient High Elves building.
Building materials of wood were banned, and fire sources were strictly prohibited. The Forest Elves relied solely on their manpower to construct this magnificent white castle, one that rivaled the grandest of head of state residences across the continent. In a place where nature was revered and the only structures allowed were simple tents, the ruler of White Bone Castle stood above all others.
After all, so-called privilege was manifested through being able to do what ordinary people weren't allowed to do.
