The Iron Ring
Much like Amber’s Golden Circle, the Iron Ring is the immediate sphere of influence exercised throughout the Shadows beyond the Nine Worlds. These Shadows take on the characteristics of the nearest portions of the Nine Worlds, lessening with distance from the Great Rune itself. Those nearest to Asgard tend to be the “light” and “magical” realms. The ones near Helheim are the dark and often sinister. The ones spun out around the middle are the more “common” worlds. In the case of the “gateway” Shadow of Asgard (“Hrafnborg”) is very much a middle world shadow.
