Angel Island (also known as the Floating Island) is a fictional island floating high in the air ''Sonic the Hedgehog'' video game series. It was first introduced in the video game Sonic the Hedgehog 3. The island is the home of the Master Emerald, a large, powerful green gem that keeps the island suspended in the sky. The emerald is protected by Knuckles the Echidna, an inhabitant of the Island and the last descendant of an ancient society. His mission is to stand guard over the Emerald, which is an important plot device in several Sonic games. Several thousand years prior to the games, Angel Island was part of the Echidna city, known in the present as the Mystic Ruins. It was the location of the shrine containing the Master Emerald and Chaos Emeralds, but when their chief, Pachacamac, tried to steal the Chaos Emeralds, Chaos appeared, used the Emeralds to transform into Perfect Chaos, and destroyed most of the Echidnas. The peaceful Echidna Tikal managed to seal Chaos inside the Master Emerald, but not without a price: the Echindas were wiped out and the island separated from the mainland. It remained that way until a "sky god" came to the island, revived part of the Echidna [ - ]
