this is not exactky 1,000 years from now, more like, hmmm, uh, 100 years later
I think that they will find new islands to live, and there were other toa and turuga of a different type living there. And Mata nui lived there, and had amnesia, and is in a tohunga form, that he for xome strange reason knows Takua, and he starts to remember things, about Makuta, Bohrok, and,......
Then they know a way to do other things, and later, all of the tohunga start to buld flying machines, such as Gallileo and other things, and they wil start exploring outer space, and make robots, and blah-de-blah-de-blah,....
