Olisi

The Kanohi Olisi is the Mask of Alternate Futures, worn by Karzahni. It allows the user to project a vision of an alternate future or a possible future into their and another's mind. The user can use their thoughts or thoughts of the victim to create the alternate future.

Example Usage
Karzahni used his Olisi to create a vision of what would happen if Mata Nui died. The sight shocked him so much that he was momentarily stunned, allowing six victims to escape.
