Mask Maker's Tool

The Mask Maker's Tool was a device created and once used by the Great Beings to create masks.

Early History
The Mask Maker's Tool was created by the Great Beings during the creation of the Matoran Universe. They used it to create Kanohi masks, although it is unknown which were created using the tool. At some point, a Great Being accidentally dropped the tool into a pile of discarded masks, infusing some of it's contained power into the mask. The result was the Mask of Catastrophes.

At some point, the tool ended up on Powai Nui. It was found sometime, and caused a series of events which Turaga Maroona said were "bigger than herself".

The Feral Plains
The tool was later found by Keelo after he was transformed. When native Toa Lewok was captured and brought to him, he had an idea.

Later, Dark Hunter "Alchemist" (who had been recently beaten and exiled by Keelo) stumbled upon Keelo. At Keelo's commands, Merdana him Lewok and the Tool, which he introduced to "Alchemist". He then used the Tool to activate Lewok's Vehere, using this to overload "Alchemist"'s mind, essentially killing his brain.

Appearance
The Mask Maker's Tool is the size of a basketball and is apparently light for a machine of it's size. It is composed os a metal rod with a blue light on the upper end and eight arm-like appendages, which close around the blue light when not in use. When in use, the appendages open up and the blue light glows.

Usage and Powers
When activated, the wielder is given the power over the powers of nearby Kanohi masks, and can do virtually any action regarding one of them. These actions include:
 * Activating a Kanohi without consent from it's wearer
 * Controlling a Kanohi's power once activated
 * Increasing the intensity of the effects of a Kanohi temporarily
 * Lowering the intensity of the effects of a Kanohi temporarily
 * Shutting off a Kanohi's power manually
 * Temporarily making a Kanohi's power unable to be activated

Trivia

 * Lewok's mask power and the idea for the Mask Maker's Tool were finalized at the same time. The Vehere was essentially designed so that Keelo could use the Tool and the Vehere for many purposes, such as communication and destruction.
