A couple of weeks ago, DC Comics pulled back the curtain on the long-teased Trinity War. The event is a two month crossover between three of DC's marquee titles -- Justice League, Justice League of America, and Justice League Dark -- that pits the three teams against one another in ways we won't expect.

Today, DC has revealed that there's more -- the storyline will be getting supplemental tie-in chapters in some of the tale's related books. Namely, Trinity of Sin: Pandora, Trinity of Sin: Phantom Stranger, and Constantine Though Trinity War itself doesn't begin until July, DC is touting June's release of Pandora #1 as a "prelude" to the event, underlining the importance that the mysterious character will play in the events to come. For more insight on these tie-ins and what the big story is all leading to, I had a quick chat with editor Brian Cunningham.

There has always been big plans for Pandora. It was no accident that she popped up in every New 52 launch back in September 2011. And all those roads have been leading toward Trinity War. In fact, I urge everyone to go out and pick up a copy of Pandora #1, on sale in June — that one brings us full circle since the New 52's launch in many ways.Summer is traditionally the big "summer popcorn extravaganza," and Trinity War definitely qualifies. It's not only the first New 52 meeting of all three Justice League teams, it's the first time we'll see how they all interrelate. And what's really fun is that they don't all get along, as you can probably figure out from that gorgeous Ivan Reis triptych image that everyone's seen by now.Frankly, it feels much more a part of the fabric of the DC Universe if it's within the books themselves. It feels more important. And there's an opportunity to see the art of three extremely talented guys such as Ivan, Doug Mahnke and Mikel Janin. If it were one mini-series, we'd probably miss that opportunity.And if people really want a big mash-up mini-series with DC's biggest characters, well…it's coming.The tie-ins aren't essential reading, but they do give more context to the larger tapestry of the story. Constatine #5 will see John interact with Shazam — essentially two con artists trying to outwit the other, which is great fun. Phantom Stranger #11… I can't get into what that's about without spoiling Justice League #22's shocking events, but suffice to say, it puts the Stranger in an extremely difficult spot. And Pandora, as I've said, is at the heart of this crossover. She's the engine that drives it.New titles, definitely. I'm already two scripts into one of them, and so far, it's the biggest DC story in scope that I've ever been involved with. I can say with no hyperbole that it rocks the DCU to its very core. It's that good. I wish I could say more!The mystical side of the DCU is just so rich to mine from. It's always a tricky thing to manage the parameters of magic, but one thing I've focused on the most is: What are the consequences of magic? That's become a huge theme in both Justice League Dark and Constantine, and guys such as Ray Fawkes and Jeff Lemire totally get that. It's why I love working with them.The Question plays a key part in Trinity War. If response is positive, I'm sure anything's possible.I love the character, so never say never!
