Mount Valmai was a mountain volcano located on Voya Nui. It was extremely active. The Ignika was buried deep beneath it, and Valmai held a massive complex devoted to this purpose. Leading to the mask was a staircase of 777 steps. Three teams have been known to travel there and survive: Toa Jovan's team, the Piraka, and the Toa Inika.
