On Twitter, "Justice League" scribe and DC Comics CCO Geoff Johns revealed that he, Ivan Reis and Joe Prado have started work on "Rise of the Seven Seas." The storyline was originally teased in the conclusion to Johns' run on "Aquaman" last November.

In the Tweet, Johns reused some older "Aquaman" artwork for his announcement, revealing that he, Reis and Prado were at work on the story and adding, "The team is back." "Rise of the Seven Seas" was originally promoted as a "Justice League" storyline, but it is unclear at this time if that is still the plan.

In Johns, Sean Parsons and Paul Pelletier's "Aquaman" #25, Arthur emerges victorious against the usurper king Atlan, taking his rightful place as King of Atlantis with Mera at his side. However, in the issue's final pages, Orm and his human companion Erin look out over a rainy Louisiana street, when the door bursts open to reveal Nerus, King of Xebel -- the Second Sea -- who reveals that he knows the locations of the seven seas. He offers Orm the opportunity to join him and allow the seven kings to rule the planet once more.

"We are introducing this mythology piece called the Seven Seas in my last two issues and that's going to continue into a big 'Justice League' story next year," Johns explained shortly following the issue's release. "It warrants Aquaman getting help from the Justice League. It's too big for him to handle alone, so the seven seas, the seven members of the Justice League -- it's all going to be a nice, big story."

Johns is currently working with artist Jason Fabok on "Justice League," which is in the thick of the "Darkseid War" event.
