Mask of Clairvoyance

"Only Toa Gaaki stood off to the side, her eyes fixed on the ocean but unseeing. The Toa Hagah had seen her like this before. She was focused inward, using the power of her Mask of Clairvoyance to see things they could not."

- Narration, Dwellers In Darkness

The Mask of Clairvoyance was a Kanohi that gave its user the power to see into the near future. Using the mask was very debilitating; the mask used the wearer, in a sense, rather than the other way around. This was because the wearer had no control over what they would see or even when they could use the mask.

This mask was always on at a low level; despite this, the mask's power could not contact the wearer's consciousness if they were trapped in a very powerful mental illusion.

Example Usage
In Dwellers in Darkness, Gaaki's Mask of Clairvoyance showed her that Zaktan would die (or at least appear to) during the Toa Hagah's hunt for Makuta Teridax.

Great

 * Toa Hagah Gaaki - Lost Kanohi when she became a Rahaga--since restored.

Trivia

 * Although it seriously affected her mentality, Gaaki kept her Mask of Clairvoyance because of its usefulness.
 * While a Mask of Clairvoyance-wearer could foresee the future, they could not do anything to change it.
