Great Glade was the largest and most influential of the three great cities in the Third Age of Flight. It grew around the Free Glades, a settlement originally established in the Second Age as a safe haven for those fleeing from hardship and tyranny. In Great Glade, the original Free Glades formed the smallest but the most ancient of the city's twelve districts. Its economy was chiefly based upon the phraxdust obtained in the mines of the nearby Twilight Woods, which was used to power everything from sky ships to phraxmuskets. Like the ancient city of Sanctaphrax, Great Glade's Cloud Quarter served as the seat of knowledge and academia in the Edge.
