The Four Bridges Glade was a Naga construction, above the River of the Sky, made of worked quartz crystal of many colors. They crossed a cliffside dell in the center of the Shinomen Forest, giving access to the otherwise secluded vale, an empty glade. Each bridge had a white stone marker, portraying a kanji of the four elements (Earth, Water, Fire, Air), and each bridge pointed in its respective direction (East North, West, South).
