Canopy
Canopy, the region of Aurum at the highest altitude, is made up of the leaves of the world tree. Mostly stuck in perpetual day, with all of the island-like leaves surrounded by The Osone, the area is an awful lot like an endless archipelago of paradise islands. Each with their own culture and tradition.
Thankfully, despite their differences betwixt one-another, the islands of Canopy are largely ambivalent in regards to eachother and tend to leave well enough alone.
