Story Summary
The Toa Nuva, Turaga and Matoran finally made it to Metru Nui again. Turaga Dume told the Toa Nuva that Mata Nui was dying and they needed to go to Voya Nui to save Mata Nui with the Ignika, Mask of Life.

Meanwhile, six ex-Dark Hunters, calling themselves Piraka, posing as Toa arrived on the island first and enslaved the Matoran with their Antidermis Zamor spheres. The Toa Nuva arrived and fought them, but lost. Meanwhile on Metru Nui, Jaller and a group of Matoran left for Voya Nui to aid the Toa Nuva, traveling through the realm of Karzahni. There, Karzahni gave them new masks. They found Toa Canisters there and went to Voya Nui in them. When they arrived they were struck with lightning from the Red Star and transformed into Toa. They called themselves the Toa Inika.

The Toa Inika and the Piraka clashed, and eventually both groups headed down to the Chamber of Life where the Mask of Life was contained. The Piraka got there first and were beaten by Vezon, Guardian of the Mask. Soon the Toa arrived and fought Vezon. They discovered that the Mask of Life, on the back of Vezon's head, wanted Toa Inika Matoro as a new guardian for it. They used a special zamor sphere to freeze Vezon and his steed, the Kardas dragon, in time and space and Matoro took the Mask. But it floated away and into the sea surrounding Voya Nui, down to Mahri Nui, an island that rested on The Pit.
