Pyron has arrived on Oa to feed on its energies and those of the lanterns. The Guardians put full faith in the lanterns so they aren't involved. who wins?
It's not likely that a being made up of so much raw power such as Pyron would be able to approach Oa undetected, so the Lanterns would figure out how to use their rings together to make some sort of energy trap, or many even entrap Pyron in the central battery.
