Brotherhood of Makuta

The Brotherhood of Makuta was created to serve Mata Nui's will. It's leader is unknown, but many assume it was Makuta, hence the name. Their gaurdians, the Toa Hagah, were there to protect them. But for unknown reasons, the Brotherhood betrayed Mata Nui and started enslaveing Matoran. They also had a prized Kanohi mask in their hands, the Mask of Light.
