Sun Holes

"Just because the suns hang above us now does not mean they will always burn bright."

- Lhikan, Legends of Metru Nui

The Sun Holes are a pair of apertures in the dome above the Island City of Metru Nui.

History
The Sun Holes were constructed by the Great Beings and Matoran laborers during the construction of the Matoran Universe. The openings are barricaded with a membrane of impermeable energy which prevents external materials from entering. While functioning as the Great Spirit Mata Nui's eyes, they allow natural sunlight to pass through into the Dome of Metru Nui. During the Great Cataclysm, the Sun Holes were obstructed due to the accidental creation of the Isle of Mata Nui above Metru Nui's dome. One was covered by a glacier on Mount Ihu in Ko-Wahi and the other was covered by the coral and dirt that accumulated at the bottom of Naho Bay in Ga-Wahi. For over one-thousand years, the Sun Holes remained obstructed. When the body of the Great Spirit was re-awakened, the Sun Holes were cleared of debris and re-opened. However, when Makuta Teridax assumed full control of the Great Spirit, the membranes of the holes ominously turned to red.
