The Temple of Time is the Protector's most sacred place. The Protectors and Ekimu believe Temple of Time is the oldest structure on the entire island, and is among the few structures that escaped destruction during the battle of the Mask Makers. They also believe that the temple mystically connects Okoto with other places, including distant worlds across time and space. When the Protectors finally realize that their own powers are not sufficient to stop the rising evil on Okoto and all hope seems lost, they go to the Temple of Time to recite the Prophecy of Heroes and summon the Toa.
Kept within a secret vault in the Temple of Time, the Mask of Time possesses powers that even the wisest elders don't completely understand. According to ancient legends, the Mask of Time is actually a fragment of a larger mask; it is the upper half of a larger mask.
