Question for the lore-savy anons here (game ORAS related):

As Kyogre / Groudon was artificially awakened (after Team Aqua / Magma exposed it to its corresponding orb), would its nemesis naturally awake as well?

As far as I can tell, both always appear as a clashing duo, but there was always something naturally occuring that caused them both to wake up (in the anime (Mega evolution special), there's this giant crystal thingy; in Hoenn's lore, there were these energy surges which both desired). During the events of ORAS, there wasn't such a powerful energy source present. Meaning they shouldn't wake up on their own, right? The opposite team also takes on a mediatory stance, showing no interest in waking the other legendary up (at least in the games).

Additionally, would Rayquaza intervene when only one of the two went on a rampage? Or would it be necessary for both Kyogre and Groudon to clash with each other?
