Alta Nui

Alta Nui was a Great Being research facility, and later a massive island inhabited by the Matoran species. It is abandoned, due to a massive catastrophe

History
Alta Nui was formed on the surface of Aqua Magna quickly after The Shattering, due to massive volcanic activity in the area. Some Great Beings who did not leave after The Shattering decided to use the island as a research facility, developing weapons and technology. They disappeared, and it is unknown where they are.

Shortly after the Great Cataclysm, a large number of Matoran traveled outside the Matoran Universe. They were accompanied by a Toa team consisting of a Toa of Earth, a Toa of Plantlife, a Toa of Fire, a Toa of Stone, a Toa of Iron, and a Toa of Ice.

They found the island, although it was too small to house all of the Matoran. The Toa team sacrificed their Toa powers to form the island. The Toa's of Earth and fire raised massive amounts of earth from the ground, and formed lava to proide more mass. The raising of the land brought up the original island; it was connected to the original island by a long, thick pillar. The Toa of stone and iron gave shape to the new island, making it more than one flat surface. The Toa of plantlife populated the mass amount of the island with multiple types of plants. The Toa of Ice sacrificed his Toa power by turning six Matoran into the new guardians for the island. The Matoran later named the island Alta-Nui.

After the island was terraformed, The Matoran began to build structures and inhabit the island. They discovered the Great Being's lab, and utilized all of the technology it had. They were able to reverse-engineer the technology with their own, and were able to mass produce products that were much requested by the inhabitants of the Matoran Universe.

The island's technology opened up a lot of trading opportunities, and in no time, massive cities were being built. The Matoran even hollowed out the pillar holding up the original island, which was called The Stalk ,and inhabited that island as well.

During this period, Alta Nui experienced a massive boom in trade, and the island flourished. Although there had been multiple attempted invasions by factions such as the Brotherhood of Makuta, their advanced technology repelled the attackers every time.

Unfortunately, through a plan devised by Makuta Xelva, a massive invasion was launched on Alta Nui. However, during the assault, they accidentally shot The Stalk, causing the island on top to fall an collide with the lower part of Alta Nui. Almost all Great Being technology housed on Alta Nui was destroyed, and very few Matoran survived, and only half of the islands current Toa team were left. They evacuated Alta Nui, avoiding the Makuta's fleet, and relocated to a different island.

Alta Nui was in such ruin, and with the Great Being technology destroyed, the Makuta used it as an island for the Visorak. During the reformation of Spherus Magna, Alta Nui was merged with the planet.
