Sorry I have to.
Oh yeah no troll. The Tribe you are asking for is disbanded after an epic war between them and their leader, who is now the lead developer of this game. Pretty awesome huh

For now you are stuck with the 3K with Judaism and his gang. Basically from what I've heard we have:
Candy gang (Alloin or someone, long gone I think)
Rustatorium (the Russians)
Kiken-Kitsui-Kitanai aka KKK (Judaism and his friends). No hard feeling KKK guys, I am joking around -_-
The MM tribe (Jwhitehorn, now Johncarver, dissolved sometime ago)
Darworth (Darworth the one man army and his alts)
Arcadia the town (the venerable town in which Latikai and others live)
And some other factions. The dominant now are Darworth the one man army and KKK by Judaism and friends.
