The Bionicle story continues after Mata Nui was banished from his body by Makuta Teridax, onto a planet called Bara Magna. With the exception of a few wildlife species, Bara Magna is a barren desert planet which only supports few resources, so each tribe on the planet has a few warriors, called Glatorian, to battle for them. These resources, such as food and water, are distributed accordingly. The villagers of this world are known as Agori. The Agori together make up six different tribes, each affiliated with a region. After the Mask of Life lands on Bara Magna, it creates a body for Mata Nui to use. Mata Nui then teams up with a few Glatorian to defeat the combined forces of the Skrall and Bone Hunters, two major threats to the villages, and look for a way to return to his body. With the help of his new Glatorian and Agori friends he exposes a traitor known as Metus and defeats the Skrall and Bone Hunters. He helps the villages of the world to unite, taking all of the giant pieces of robot and linking them into a large prototype robotic body, a body like the one the Matoran Universe resides in.
