Preserves were maybe some of the last places the Ancients lived and... did their stuff? And either grandpa created the bioroids or some other ancient did, and WHOOPS, they can't be controlled?
I'm guessing Ayata's planet is another preserve, where instead the Ancients left some descendants who like... inbred or something.
