Keystone

The Keystones were six pieces of a tablet detailing the way that the Toa Nuva were to awaken the Great Spirit Mata Nui that was kept with Av-Matoran. Over the years, the tablet was broken and the pieces were lost over time. According to what Kopaka could read after obtaining three of the pieces, the Keystone said that the secret to reviving Mata Nui was in the swamp below Karda Nui.

Below are the locations of the six pieces and current status of each piece.
