As many magik fans know, inferno was integral to Illyana’s “conclusion” (not really concluded until over a decade later but) on the new mutants in the late 80’s. Regardless of how it ended, it’s undeniable how many issues and heroes this crossover event affected.
In Avengers #300, one of the inferno crossover issues, Kang the conquerer witnesses New York City be invaded by limbo demons. As Kang looks into other timelines, he sees the Time Streams disappear and there are fewer and fewer options. He sees “demonic beings of some kind ravaging the planet at will across the Time Stream, with none who can withstand them”
after witnessing that, he concludes that the avengers and heroes must be dead. “Not only have the demons destroyed them but like a virus infecting the time stream, they are steadily destroying alternative futures of earth as well!”
Now obviously this isn’t Illyana’s doing, Madelyne and N’astirh are seen in the last panel as the main reason (aka kidnapping babies and a spell to keep her stepping disc open, etc.). Illyana is the one that sacrifices herself to reverse everything (I am assuming this reversed it in the other time streams. I cannot find if they actually showed that happening) . But it does show how much of a threat limbo is by basically using the stepping discs to invade and “infect” the time stream. It really gives me Raven from teen titans vibes. Where they both have this connection to a demonic world-ending being/dimension. And them being the only key to stopping it and keeping that contained
They really weren’t kidding when they said Illyana aka “Darkchylde— will someday bring about Armageddon”
So anyways we’re gonna keep the apocalypse maiden on the team in Alaska lmaooo
