For months, the true nature of Pandora’s Box has been a mystery. Where did this powerful device come from? Why does it possess those who try to open it? And what is it truly capable of?

This week, the penultimate chapter of “Trinity War” revealed that Pandora’s Box is in fact a doorway – but to where? Place your bets in the comments below, but in the meantime, leave it to The Outsider to open it and unleash his ultimate plans for the Justice League. 

“The Secret Society capitalizes on every potential misstep the heroes have made, and the consequences of each misstep will haunt the entire DC Universe in the months to come,” editor Brian Cunningham recently teased to NEWSARAMA. “The Secret Society leader is an extremely meticulous planner. He's the kind of guy that no one will see him coming, and that'll make it very difficult for our heroes to plan around. Not impossible, but very, very difficult.”
