|Primary Residents||Toa, Mask makers, Protectors|
The inhabitants of Okoto, the Protectors and the Maskmakers, lived in harmony at one time. After the battle between Ekimu and Makuta, the island was severely damaged and the Mask makers rendered into unending slumber. The Mask of Creation, Mask of Control, and Mask of Ultimate Power were scattered and remained hidden to the inhabitants for a long time. Later, the Toa arrived, preparing to find the masks and restore order to the island.
Okoto was an environmentally diverse island, with six distinct environments corresponding to the six elements of the Protectors, roughly divided by a mountain range. Each region was home to a village of Protectors. Elsewhere on Okoto were the ruins of an Ancient City, guarded by the Lord of Skull Spiders.
|Region of Fire|
|The Region of Fire is volcanic and fierce. Magma spills from the huge mountain ranges and run south forming broad, burning rivers that meet the Great Sea in huge, hissing clouds of smoke. The region is home to the Protector of Fire and Tahu, the Toa of Fire.|
|Region of Jungle|
|Okoto’s jungles are dangerous places full of gigantic trees and savage wildlife. The jungles hold the most ancient of the Protector Ruins, now overgrown and forgotten. The region is home to the Protector of Jungle and Lewa, the Toa of Jungle.|
|Region of Ice|
|Glaciers and tundra permanently freeze the northern part of Okoto. Great snowstorms blow across the region flashfreezing everything. The region is home to the Protector of Ice and Kopaka, the Toa of Ice.|
|Region of Stone|
|The great barren desert spreads across the northwestern part of Okoto. The most dangerous phenomenon in the desert is sandstorms that blow across the wasteland. The region is home to the Protector of Stone and Pohatu, the Toa of Stone.|
|Region of Earth|
|The western part of Okoto is rich with obsidian fields. It is a black, glasslike and nightmarish place full of treacherous ravines, crevices and deep rifts. The region is home to the Protector of Earth and Onua, the Toa of Earth.|
|Region of Water|
|The Region of Water is composed of lakes and thundering rivers that form large deltas as well as strings of fertile islands along the eastern coast of Okoto. The region is home to the Protector of Water and Gali, the Toa of Water.|
