Zinkenstill Island is but one of many numerous islands that dot the Phantagrande Skydom. These islands are home to four races who were once bitter rivals but then unified as one against the aggression of the Astrals. That cooperation between archipelagos continues to this day. At around the same time of the conflict with the Astrals, peculiar creatures came into existence. These creatures simplemindedly attacked people but a few types of creatures possessed the intelligence to organize into societies. Lastly, there are those that were imbued with immense power by the Astrals. They are known as the Primal Beasts.
