Makoki

From Lego Bionicle

The Makoki stone was an artifact used by the Rahaga to lock up the Mask of Light. The stone was then split into six pieces and hidden all over the island of Metru Nui. The Toa Hordika had to find each piece and bring them together to find and retrieve the Mask of Light.

Each piece of the Makoki stone was hidden in a different metru. The Toa Hordika each searched for a piece in their corresponding metru, eluding Visorak and surving dangerous traps along the way.

Once the six pieces of the Makoki stone were reunited, the Toa Hordika used them to retrieve the Mask of Light.
