Angel Island

Angel Island (originally known as The Floating Island) is a large landmass which floats high above the planet's surface. Originally a part of the continent of Downunda, the Echidnas living in the city of Echidnaopolis decided to use the powers of 12 Chaos Emeralds to lift their city off the surface to avoid destruction by a White Comet. Since then, Angel Island has been the home of many different species, the two largest being the Echidnas and the Dingoes. After the Dr. Eggman-backed Dingo Regime's mass genocide under Kage Von Stryker, the Echidna population was left in shambles. Those who survived were relocated to Albion by Enerjak, to ensure the survival of their species, while the Dingos themselves were disarmed and exiled to Sandopolis. It is largely uninhabited except for the Dingoes, agents of the Knothole Freedom Fighters, Chaotix and the island's last Guardian; Knuckles.

Hundreds of years ago a group of Echidnas known as the Knuckles Clan, having set out from their homeland of Albion, eventually settled in a region of Downunda and built the city of Echidnaopolis. (KtE: #12)

The technologically-advanced city thrived on the mainland until roughly 600 years ago when the two scientists Jordann and Kayla-La discovered the White Comet that would soon impact directly on the city. Desperate to save their home, Kayla-La developed and proposed a plan to physically move the city out of harm's way using the power of Chaos Emeralds. After excavating twelve of the rare and powerful gems, the Chaos Chamber was established to harness the energy of the emeralds. After the Fire Ants dug under the foundations of the city, separating it from the planet's surface, Echidnaopolis lifted into the sky, becoming the Floating Island. A large crater marks its former place in Downunda.
