I recently had a dream about how the two generations of Bionicle connected. That the villagers were created by a really young great being who fled Spherus Magna long before the Shattering. I don't remember much of the miniscule details, just that she was really sick and could only talk to the toa by answering one question from each of them.
I also had a dream once that in 2017 we get six sets, combiner models of the 2015 and 2016 toa. Pieces from each set could be used to great the great being. I don't know her name, so I've just been calling her Kare.
