How did the Ga-Matoran of Metru Nui purify the liquid protodermis they extracted from the Silver Sea? We know they used pipes to transport it, but where did all of that go? Were vats involved? Was it centrifuged, or was another material added to it to cause some kind of reaction?
Don’t know, Wasn’t something we ever discussed.
I guess that opens up some possibilities. I’ll come up with some ideas.
