In today's X-Men Monday, Ewing was asked if we'll be seeing more of Storm's mystical/magical heritage moving forward and he ended his response with:
"Anyway, with that treasure chest now open and on display, it seems a shame not to do more with the treasure inside. So the upcoming story will have a magical component enter proceedings at some point, with an emphasis on
'mutant magic'."
Mutant magic is a term started in Excalibur by Tini Howard. In an interview during X of Swords she said:
“To Apocalypse, there’s still a lot of work to be done, a mutant cultural heritage and traditions to build—things like the idea of magic,” Howard said. “Anthropologically, culturally, magic is an expression of wisdom and ideas that are developed over the development of a society. So Apocalypse is getting into these ideas of building a concept of mutant magical tradition.”"
Who will be making his return to the stage in next month's Heralds of Apocalypse written by Ewing? Apocalypse. He introduced the concept in Excalibur while working with Betsy and the team to access Otherworld. If Storm has to combat him/Genesis in a magical setting, Betsy has studied A's work...
Howard said on a podcast that Betsy would be appearing in another book to provide information. It's possible all of this is what she was talking about. Without getting into the whole story, there's also the fact that Apocalypse set up the protection and activation of the Siege Perilous which now serves as a magical gate between Krakoa and Otherworld. What we do not know is if Apocalypse knows that Betsy and Rictor know that it was him that orchestrated its presence. Who told them? His son.
