Azuria is notable for moving faster in time than the rest of the galaxy due to existing at an accelerated rate in the time stream; to an outside observer, millennia can pass in mere minutes. Because of this, several varying environments are observed by Sonic during his stay on the planet, changing from nothing but muddy terrain to forests and, further down the line, villages and modern cities.
The development of Azuria was irrevocably changed by the arrival of Sonic the Hedgehog, who crash-landed on the planet in an escape pod. Somehow immune to Azuria's accelerated time, Sonic watched as life evolved around him on the planet and was influenced by his image. Religion and war broke out around Sonic's presence in the escape pod, until the Azurites realized that time passed differently for Sonic than for them. A brilliant scientist, Professor Parg, responded by developing the Temporal Decelerator, which slowed down time enough for the Azurites to interact with Sonic and enable him to depart their world.
