Guild Wars 2

Hi all, and quick question: can anybody tell me what the story reasoning behind SPvP is, or where I can find that information? I mean things like: where exactly are the arena locations in the real world, why are the battles happening there, who are we fighting (of course the other players, but story-context wise, who are they supposed to be?) and why?
Thanks a bunch for any and all answers/comments &

Cheers

I think this is like the fractals. The tournaments are hosted on different locations, this time picked by the tournament hosters, between 2 queing teams who wanna compete, and that’s all.

No real reason.
