Nothing is known of the Book's history, aside from the fact that it was in the possession of Turaga Nokama by the time that the Toa Mata arrived. After a wandering Matoran named Takua helped to save Ga-Koro from a Tarakava attack and Po-Koro from an epidemic, Turaga Onewa decided that the valiant Matoran was worthy of being the island's Chronicler, and gave Takua a golden chisel to give to Nokama as a sign of the Stone Turaga's faith in the Matoran.
