Ko-Wahi

Ko-Wahi was the mountainous, snow-covered region of Ice on Mata Nui. It was the location of Ko-Koro, the village home to Turaga Nuju, the Ko-Matoran and their protector, Kopaka, the Toa of Ice.

History
Ko-Wahi was created on Aqua Magna during the Great Cataclysm, when Mata Nui was rendered comatose by Makuta. After he collapsed face-up, into the seas of Aqua Magna, his camouflage system malfunctioned, creating an island over his submerged face. One region of the landmass rose up into high, icy cliffs and snow-covered peaks.

When the Toa Metru first scouted the island to pick the locations for the Matoran's villages, this snowy region area would come to be known as Ko-Wahi. Nuju decided upon an icy peak on top of Mount Ihu as the site for the new Ko-Matoran village. When the Matoran of Metru Nui were later brought to Mata Nui, Turaga Nuju led the Ko-Matoran to an area near Mount Ihu's peak, and here they built the village of Ko-Koro.

When the Toa Mata arrived on Mata Nui, Kopaka journeyed here to find his Hau, the Great Mask of Shielding. It was also here that Kopaka met Pohatu, the Toa of Stone.

After the defeat of the Bohrok, Kopaka became a Toa Nuva and his Nuva Symbol appeared in Ko-Koro. One of the Bohrok-Kal later journeyed to the city to retrieve the Nuva Symbol so they could all awaken the Bahrag, but the attempt failed, and the symbols were returned.

When the Matoran migrated back to Metru Nui, Ko-Wahi was abandoned. The Toa Nuva later came back to awaken the Bohrok swarms to prepare for Mata Nui's awakening. The area was then leveled by the Bohrok.

Ko-Wahi was permanently destroyed when Mata Nui finally awakened.
