Eh, that does make your position something of a side-note though. If he wants to strike at the -Arena- proper he's going to want to fight people fighting for it.

It does raise an interesting question though, surely at least some of your characters must be on the side of the Arena? But what exactly is the Arena? The Mulitverse? The Nexus? I guess the Multiverse will have to do for a casual explanation, as we don't play one or two characters as ourselves in the Arena but tell the stories of a vast number of individuals (particularly in Nobody's case ;d).

The idea of an invasion by another site or clan does away with the "fiction" of the arena. Much like professional show wrestling where each organization has good and bad guys doing story lines. When another organization "invades" those lines are put to the side while the "organization" bands together to push out the invaders.
