Aqua Magna

Aqua Magna, also known as the Endless Ocean Planet or the Great Sea, was the planet which Mata Nui crash-landed on as a result of the Great Cataclysm.

History
Aqua Magna was originally located on Spherus Magna. When the Shattering occurred, Aqua Magna broke loose and became a moon of Bara Magna.

Just as Mata Nui, on his way home after completing his mission, passed Aqua Magna, he fell into a coma because of a virus which the Brotherhood of Makuta had infected him with, and crashed on Aqua Magna. In the impact, a part of the Mainland broke loose, forming the island which was later known as Voya Nui. His camouflage system also created an island over his head, an island which was later known as the island of Mata Nui.

After the Toa Mahri destroyed the Stone Cord, Voya Nui sank back to it's original position, leaving the Island of Mata Nui the only landmass on the planet.

When the Toa Nuva awoke the great spirit, now controlled by Makuta Teridax. When Teridax arose, the Island of Mata Nui was broken, destroying the last landmass on Aqua Magna.
