Matoran-Rahi War

The Matoran-Rahi War was a conflict between the matoran of Mata Nui and the local rahi, enslaved by Makuta Teridax to do his will. Teridax was attempting to exert his control over the matoran, and thus turned the island's rahi against the villagers. However, guided by the wisdom and courage of the Turaga, the matoran refused to cower to the threat. Defense forces sprung up in Ta-Koro, Le-Koro, and Onu-Koro in the forms of the Ta-Koro Guard, Gukko Force, and Ussalry, respectively.

Conflicts

As the threat of rahi increased, several of the bravest matoran organized resistance. Jaller organized the Guard, Kongu created the Gukko Force, and Onepu formed the Ussalry.
