Oh. I've come to some decisions regarding how the 'factions' are set up.
Some are obvious, Orks are Orks, etc.
But some, like Space Marine Chapters, are specific groups or clubs within the school,
For example, the Ultrasmurfs are the football team, where as the Space Wolves are the Hockey team(with a very bad foul record). Noise Marines would mostly be in the Music club or School Band, etc.
