Southern Continent

The Southern Continent (also known as the Mainland) was an unknown landmass that Voya Nui broke off from. Karzahni sent most of his "fixed" Matoran there when he was done with them. The mainland was underground, on the same level as Metru Nui and in a dome that was far south of it. When Voya Nui split from the continent, a huge hole was punched in its dome, flooding the landmass with water from the Endless Ocean of Aqua Magna. Makuta Mutran was assigned to the center of the Mainland. Matoran from Voya Nui and Mahri Nui traveled to the Mainland before the The Cord was destroyed.

When Mazeka and the Teridax from another dimension were teleported to the Matoran Universe, they ended up somewhere at the Southern Continent near a Ba-Matoran village.

After Teridax's death the inhabitants of the mainland immagrated to Spherus Magna.
