"And why does this thing exist again?"

- Xavlo to Demios

Powers
This makes it very desired among thieves and other forces of evil.
 * The Mask of Reality has the power to remove anything off the face of reality excluding other Legendary Kanohi.
 * When the thing has been removed, life will change as if the object/being had never existed. The only one to remember if that object existed would be the user that removed it.
 * The problem with this mask however is that anything / anyone can use it. All the user needs to do is think of something and it will turn into, nothing.

History
The mask's history isn't known very well, such as the mask's location; which has been unknown for thousands of years. The mask was created by the Great Beings, they had chosen a Matoran named Vremik to deliver the mask to a secret location somewhere on Zutal. He had no idea what the mask was so he had no temptation his to use it. Along his journey to this secret location he was ambushed by what he called a 'four armed mechanical creature' somewhere in the Zuhu Mountains. This creature has snatched the mask and attacked Vremik leaving him injured in the middle of the mountain range.

He was found by another Matoran, Kipou while he was climbing. When Kipou brought him back to the nearest hospital where Vremik then told him what happened. After, Kipou reported this to the island's 'Specialist Cases Service'.
