DC seemingly changed the entire aspect of Pandora as we saw by 2013 and installed the whole 7 Deadly Sins aspect by the Forever Evil lead in. There was the Trinity of Sin branch of titles they did to explain more of the back story involving Pandora , The Question and Phantom Stranger. But all of them was cancelled because they were awful . Bt 2016 they decided to just kill off Pandora and never really bring up the Trinity of Sin at all.
