Mangaia

The Mangaia (which meant Guardian in Matoran) was the semi-dark and twisted lair of Teridax. It housed a gate to Metru Nui, a pool of Energized Protodermis and various weapons, oddities, and technology for use against the Matoran. It was also attached to the Bohrok Nest.

When the Matoran arrived on the Island of Mata Nui, it served as Makuta's lair. Here he created Kraata, submerged them into his pool of Energized Protodermis, and transformed them into Rahkshi. He later used the Rahkshi to find the Mask of Light, in which he was unsuccessful.

The Toa Mata battled him here, and Teridax was defeated. Takua ventured further into this lair and discovered the Bohrok.

Takua, now Takanuva, later returned to fight Teridax. Their battle was a Kolhii game which ended with Takanuva's victory. Afterward, he and Teridax fell into the pool of energized protodermis, fusing them into Takutanuva. Takutanuva lifted the gate to Metru Nui, and he held it up while everybody crossed through and bringing Jaller back to life. Weakened after the revival, the door crushed Takutanuva, destroying Teridax's armor.

It was later looted by the Piraka. The Spear of Fusion was discovered, and the spear created Vezon.

The Order of Mata Nui later destroyed the Energized Protodermis in Mangaia.
