Are you asking why (or how) heroes exist in the City of Heroes universe? Because I do not believe that's ever been explained. I think it's just supposed to be an alternate reality where things like toxic waste giving you powers and mysitical artifacts giving you strange abilities can actually happen. Like in a lot of comics. There's no singular reason why all the heroes got their powers. That's where the origins come in. Magical origin people might have studied ancient incantations, while Science origin people had some life-altering disaster. But perhaps I misread your post? Hope that helps.
Greetings!
Feel free to point me at a link if this has already been answered elsewhere.
Essentially, what I want to know is--why here? Not "Why are all the heroes here" which has more or less been answered in the official backstory (you want to be in movies, go to Hollywood; you want to be a hero, go to Paragon), by "why are there heroes here at all?"
Is it an alien virus such as in the Wild Cards mythos? Is it some cosmic flux allowing extreme possibilities never before allowed by natural law as in the Windfall Trilogy mythos? Did it "just happen" with absolutely no one knowing what the heck is going on?
Part of the reason I ask is--what a shock--I'd like to do some writing on my characters that has a touch more to it than the "Biff! Pow!" Batman tradition of TV lore, and while I'm happy to create my own reasons for all this odd phenomena (and probably will anyway), if there is an "accepted theory" held by most of the RPrs here, I'd be just as happy to adhere to it.
So again--why here?
Thanks in advance for any answers; I appreciate the time.
