So, far as I know.
Black guild is conquering (vicious and has the sweepers)
Blue guild is having fun (Has fun)
Green guild is being neutral (shies away from conflict)
White guild is something to do with a brighter future (probably opposes black guild)
Orange guild is pretty strong but IDK what else (opposes black guild for some reason)
Yellow guild is ??? (???)
Red guild is ??? (leader is team player. Guild may be strong also)
Oh, and Vigilant eclipse (which is just Keith [which is just rofls][but this doesn't really count because it's only one guy])

Correct me if I'm wrong, which I probably am.
