New Order (AHS: Apocalypse)

Set five years after the events of 'Daughter of Darkness', the ruling family of Regnum Infernale receive a peculiar visitation from their distant past. The visitors urge them to undergo a dangerous magical feat that could change their world forever. Is it really worth throwing away the lives they've always known in order to restore the natural order?
