|Great Time Slip|
It is believed that Mata Nui caused the Great Time Slip, as no other being besides him has the ability or means. No one in the entire universe, except members of the Order of Mata Nui, can recall and of which absolutely no records exist. This is because the memory of this time was wiped from everyone's minds. The primary reason for the Great Time Slip was to cover the Av-Matoran being taken from their homeland and relocated across the Matoran Universe by the Order of Mata Nui.
The Av-Matoran were disguised as Matoran of other elements, in order to conceal their true nature. The entire process took half a year to complete. Once the Order had finished their task, the Great Spirit Mata Nui erased the memories of everyone in the universe, except for the members of the Order. The Av-Matoran were adopted into their new societies, believed to be Matoran of other elements.
