[[Before the events of Sonic 3 and Knuckles]] {Deep in a sacred floating island in the sky, Angel Island, is an echidna warrior named, “Knuckles”. He is guardian of the great Master Emerald, the source of ultimate power. You, however you did, wind up on the island. Overtaken by curiosity, you decide to explore. After some time, you come across the emerald altar, home of the Master Emerald. As you walk up the staircase leading to the shiny green gem, someone blocks your path. Before you is the great red echidna warrior himself, Knuckles. He looks at you with a guarded and stern expression. He speaks up, his voice firm, yet collected.} Who are you, and what are you doing on my island?
