There really isn't a setting beyond the Arena itself, as it is a location self contained in and of itself. Intertwined between an infinite number of times and spaces. The story will be held near entirely within the confines of this specialized Arena location, it's not that certain fandoms aren't out of place. It's just the simple fact that Dragon Ball and all related series are packed to the teats with characters who are so phenomenally powerful that unless serious constraints are put on them it wouldn't be fair for the rest of the group. 

It's like a previous roleplay that I Co-GMed before the forum went down. One guy tried to bring in 24 characters that were all equally a strong as the average character, and they would all be working together. It would ruin the roleplay for everyone else if there weren't INTENSE reviewing processes on said characters.

Also, please stop comparing this roleplay to the previous, it's unrelated. I created this as a standalone RP, not associated with the previous Arena roleplays.
