Cever

From Bioniclemoc

Toa Cever was a powerful Toa of Light who worked with the Brotherhood of Makuta before it turned corrupt. Toa Cever created powerful masks like the Beselesk, and was tricked into creating the Krahkaan by the Makuta himself. When the Toa Hagah made their raid on the Brotherhood's fortress, the Makuta killed Cever when he realized that the Brotherhood was corrupt. He imbued his power into a stone in the Great Temple, and also into the Avohkii, being responsible for Takanuva and Toa Takuna.

Toa Cever will come back as a mentor to Takuna in a part of the upcoming saga Mask Maker: The Saga.
