Kiel

Kiel is an extremely Cold Island that Makuta split in half 5 centuries ago, when the first group of Matoran arrived there. Only the 6 Ko-Matoran survived, for the bitter cold was something only they could withstand. Their Boat, the Nikila, was destroyed when they hit the Ice Talons, newly created when Makuta split the island. Matoran and Turaga crafted Ice Blades from the Ice Dagger, a Mountain taller than Mount Everest.

The Kielians invented Snow Huts, which are today used in the Frost Regions of voya Nui, Laksuj-Konom, and Bio-Land. Toa Teremeary once said,

"Those Huts are amazing, and they keep a fair ammount of Warmth!"

As he said that they keep in Warmth, other Matoran were able to move to the island. But it wasn't enough heat for Ta-Matoran and Le-Matoran.
