Hey, if you want more options then go ahead and add them. I don't mind
We could do a "School for the Gifted" scenario where the characters are all students. We could do the standard and have all the characters be between 20 and 40 (or 50). We could even do an "Aged Superhero" scenarion where the characters are very old supers living in a retirement home.
If you have an idea, share it. Let us judge it afterwards
Want an idea? Here's what I've been thinking about doing if nobody minds one way or the other:
Modern Age but rather lighthearted. Sorta like a mix between Modern and Silver Age if you will.
Multiversed, multi-dimensional, parallel Earths, endless space. Enough room for ANYTHING!
Any kind of origin. You could be an alien, mutant, genius, elven archer from Waterdeep, it won't matter.
Supers would count in hundreds of thousands, enough to cause serious changes to society as we know it. Yet, only few have the training and the skill to make actual use of their powers.
Like I said, society would have suffered some serious changes. This would include things like special schools, special prisons, even experimental towns that will only house supers.
Characters can get seriously hurt and even die, but death won't necessarily be the end. With multiverses, parallel Earths, and every kind of powers there is, there is always the chance that a dead character returns.
This is all subject to changes, of course.
