In a world not too unlike our own, where the phenomenon of superheroes is still new and the greatest among their number do not yet threaten the world order... A society that has not truly had to adapt, quite yet, but seems to be holding its breath as more and more 'supers' turn up seemingly out of nowhere, and for unclear reasons often decide to commit or fight crimes...
Another spark is offered.
It's a strange dream. One of floating in a vast airy sea, weightless and warm. An impossibly beautiful woman vaguely defined, nothing clear except her voice, rich and warm and promising.
"This is an interesting little situation, dearie. I can't explain much. Best to think of this as a dream. But this world has opened to my influence, just a tiny bit. I normally couldn't do this at all, but here and now, tonight, I can make you a little offer. If you could have powers, but with an eensy little cost... Would you want them? Oh, the trick is nothing huge. You have to be a girl to use them, that's all."
