Yeah, I think a low form of magic would be good - with there possibly being a rare few with the traditional 'wizard' magic (maybe two in the entire world or something) but its mostly potions, or through the use of runes or something similar which is obviously time consuming? And takes years to learn. And yeah, sci-fi would definitely be much more sciencey magic than anything - not believed to be magic at all, but instead technology. But yeah definitely energy orientated (lasers are pretty much energy so I guess they'd probably fall under that). Modern world none I think, unless we want to add a slight amount. Maybe.

I kind of get what you're saying about the prophecy xD Basically one that tells of the three worlds... It's hard for me to say anything without using collided. I sort of get it. Although by collided are we going for literal the worlds mash into one or people mixing from one to the other and the possibility of easy travel or something?

That also makes sense and is quite an interesting idea - the idea of another world is not foreign but is more a myth/legend that grandparents talk about but is passed off as nothing but make believe stories? 

It's making some sense xP I sort of get most of it I think
