What IS the clan, anyway?

So this is mostly going to be (hopefully) people explaining what the clan is, what it does, and stuff like that to me. I keep seeing it everywhere and it's confusing me.

Lol. You could've just asked someone and not have everyone here know you didnt know what a clan was <.<

Anyway, a clan is kind of a group of people who compete with other clans. We wage wars, and try to be the best clan. Clans generally have lots of members, but an elite, picked fighting team, to represent them. Underground Vanguard is our clan. We are ranked in the 50's in the top 100 clans I think.
