South Island

## Bio

**South Island** is a location that appears in the *Sonic the Hedgehog* series. It is an island that is known to be a treasure trove of gems and ancient ruins, that supposedly shifts along the water due to some connection to the Chaos Emeralds.

## Description

South Island is a piece of land that floats over a rich ocean. Described as a peaceful and beautiful island, South Island is a paradise blessed with abundant nature. Its fauna is mainly composed of non-anthropomorphic Animals. Its flora, however, is much more diverse and abstract; one area in particular holds many kinds of flowers that move, almost as if they were dancing, alongside tall palm trees with spiked coconuts. Topographically, South Island's terrain quickly elevates from south to north, with the southern regions being plateau-like and very low in altitude compared to the northern areas, which hold massive mountains, jungles, and huge waterfalls. The island also has a lake archipelago that flows from the northern mountains to the south east of the island, with many tall islets found on it. Despite its abundance in nature, South Island also holds many artificial territories, which include large metropolises and massive industrial complexes. Additionally, it is a treasure trove of ancient ruins, with several locations holding temples.

Many legends claim that South Island has had connections with the Chaos Emeralds since ancient times, though the accuracy of such affirmations cannot be guaranteed. Such mythos also say that the island creates distortions that cause the Emeralds to exist and that it floats thanks to Chaos Emerald energy; as a result, if at least one Emerald gets stolen, South Island will eventually sink into the sea unless all the Emeralds are reunited.
