Voya Nui

Voya Nui is an island south of Mata Nui.

History
Shortly after the Great Beings created the universe a hundred thousand years ago, they forged the Ignika Mask of Life and hid it away near an underground coastline, under a volcano that came to be named Mount Valmai. Relatively soon afterwards, the Order of Mata Nui discovered the mask's location and sent an agent called Umbra to protect it.

At some point, the ruler Karzahni was sent broken Matoran for repair, but he didn't do a very good job. Wanting the repaired Matoran somewhere out of his sight, he sent them to Mount Valmai.

Possibly around the same time, the Order of Mata Nui sent two more guardians, Axonn and Brutaka, to live in the region and keep an eye on the mask. They also took on the responsibility of secretly watching over the Matoran as well.

Around eighty thousand years ago, a team of Toa led by Toa Jovan entered the region and made their way to the Mask of Life facing and defeating all the obstacles and guardians in their path. What they needed to use the mask for is not known, but not all of the Toa survived its use. Toa Jovan later became a Turaga and became a leader to the Matoran of the region.

One thousand years ago, the Great Cataclysm struck. It caused Mount Valmai and the surrounding region to break from the Mainland and be launched up to the planet's surface, where it came to rest floating on the water. Many died that day, including Turaga Jovan and the region was from then on known as the island of Voya Nui.
