Mask of Clairvoyance

"...Gaaki stood off to the side, her eyes fixed on the ocean but unseeing. [...] 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 is very debilitating; the mask uses the wearer, in a sense, rather than the other way around. This is because the wearer has no control over what they would see or even when they could use the mask.

This mask is always on at a low level; despite this, the mask's power cannot contact the wearer's consciousness if they are 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 Teridax.

Great

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

Trivia

 * Although it seriously affects her mentality, Gaaki keeps her Mask of Clairvoyance because of its usefulness.
 * While a Mask of Clairvoyance-wearer can foresee the future, they cannot do anything to change it.
