52/WWIII

Weeks after his confrontation with Black Adam, J'onn Jonnz is still recovering from the psychic assault of seeing Black Adam's memories of the slaughter in Bialya. In an attempt to anchor himself, he psychically reaches out to the Earth to try to get himself up to date. He witnesses many acts, both good and evil, focusing particularly on Aquaman's sacrifice to save the sunken city of Sub Diego. The humans living there can no longer breathe in the water as they are used to. Making a pact with powerful beings of the Ocean, he raises the city... though the cost he must personally pay is great.
