Hard to say, but my assumption is the children sealed themselves in the vault and it was not opened in life 9, it could have been opened in life 6 and that would explain why humanity became augmented like the children, I have no clue why everyone was blue maybe the children defeated the machines of Nimrod the lesser and spliced humanity with Apocalypse's genes as again probably the last indipendent mutant in that 6th life species war.It is all speculation on my part, but the CoV are incredibly formidable not to be mentioned.Would be fun if it is shockingly revealed in the future that Moira was a clone of the human Moira put through the vault programme by the Children given that mutation to try and isolate mutants from the general population to either forestall mutant reproduction through technological immortality or to have the vault technology activated over Krakoa to develop mutants that are more technologically dependent to survive than they otherwise could, a clever eugenics programme conducted by the Children of the Vault but these are all far out ideas I think of on the spot.Have to wait for issue #18 to get any sense of what the CoV are up to
