Origin and classification#

KanokaKanoka DisksMetru Nui's most versatile artifact: flying disks equally at home in sport, combat, and crafting. disks were standard equipment across Metru NuiMetru NuiThe city beneath Mata Nui functions as the Great Spirit's brain, housing the Matoran whose labor keeps the god alive., used for sport, for defence and as the raw material for KanohiKanohiMasks that grant powers and sustain life, they're the most vital artifact in the Matoran Universe. masks. Each disk carried a three-digit code. The first digit recorded the district where it was made, the second its power, from Reconstitute at Random to Teleport, and the third its power level, from one to eight for ordinary disks.

Six disks existed at a power level of nine. They had been made on the island of ArtakhaArtakha: Master Crafter of the Great RefugeArtakha is one of the most powerful beings in the Matoran Universe, the reclusive ruler of the hidden island that bears his name, whose crafters made the Avohkii. He governed a refuge no evil could enter and armed the Toa Nuva for their trip to Karda Nui., one for each Metru, and found their way into the city, where they lay hidden in dangerous places.
