That still leaves what could be the bigger issue, no? outside of the Rilla Strip Bar and Grill, host of this years Nexus of Worlds tournament, with locations in the Lobby and HQ, everything still connects back to the three way war, right? 

Best bet is to let people create their own stories without tying into the big theme. Like the HQ, there are different reasons for everyone to be together.

My characters sort of broke the fourth wall, by referencing being on a team to earn points in a unseen Gods game against each other. No idea what reason Skally had for his characters being together.
