The world of Gangelboba
Is a world in an unknown location in the universe which is thought to be a test world, its purpose to see which creatures are the dominant creatures in the universe. So this world has thought to be created and populated at the exact same time. All people who were transported to this planet were not children but adults so that means that some unknown force moved them there in the middle of their lives.
There is one main city in this world and nearly everything is focused around it as it is right on one of the poles. This is known as the Golden City.
