Angel Island

Angel Island, sometimes called the Floating Island, is a flying continent that travels across both Sonic's World and the Earth. It was once the home of the Echidnas, and is currently guarded by their survivor Knuckles, who protects the Altar of the Emeralds that keeps the island afloat.
