Mount Ihu

Mount Ihu was a high snow-and ice-capped mountain in the centre of Mata Nui. It was named by Nuju for Ihu, his late Matoran mentor. Kopaka found his first Kanohi mask, the Hau, on Mount ihu, and later spied the other Toa gathering from there using his Akaku. It would eventually become a place where Kopaka would go to be alone and think.
