Mata Nui (Location)

Mata Nui was an island located on the BIONICLE Planet. The Toa Metru later relocated the Matoran of Metru Nui here, home to many conflicts, naming the island after the Great Spirit.

The island is 357 by 178 kio, or in Earth measurements, 303.45 by 151.3 miles or 489.09 by 243.86 kilometers.

History
The island was also chosen as the landing place of the Toa Mata.

The Toa Metru traveled in a Vahki Traport called the Lhikan to the island above through tunnels from the Great Barrier to 'the island above' with five Matoran asleep in pods. Later, they came back with the rest of the sleeping Matoran from Metru Nui. They awakened the Matoran, sacrificing their Toa Power in the process and becoming Turaga and each element of Matoran built a Koro in a region of Mata Nui.

Just a year later, Teridax infected the Rahi wildlife and turned them against the Matoran, making life on Mata Nui highly dangerous. One thousand years later, the Toa Mata arrived. They collected the masks Vakama had placed about the island. They then entered Teridax's lair and defeated him. But then, the Bohrok were released. According to their programming, they destroyed as much of Mata Nui as they could before the Toa stopped them. After Takua discovered the Avohkii, Teridax sent his Rahkshi to find it. After all these threats, Mata Nui was badly damaged, and Takanuva rediscovered Metru Nui after Teridax was defeated. So the Turaga told the Matoran and Toa about Metru Nui and they traveled back there.

After the Matoran had returned to Metru Nui, the Toa Nuva released the Bahrag from their prison so that the Bohrok swarms could resume their task of restoring Mata Nui to its former state. They recently finished the job and have returned to their nests to wait until they are needed again.

Regions of Mata Nui
The island is divided up into six "Wahi", or regions, one for each Element. Each Wahi has a "Koro," which itself has a "Suva" dedicated to the region's patron Toa. It is also said that each region has a "Kini" temple for its Toa, though the temples have never been shown in stories.

The villages were home to the Matoran people, each led by a Turaga elder, and, in the final year before returning to Metru Nui,
