1. A NBA team.
2. A famous book about the four Clans,
ThunderClan, RiverClan, WindClan, and
ShadowClan. StarClan (cats who did good deeds or did nothing wrong and died, usually from battle) guides all four Clans.
ThunderClan cats are pretty balanced, RiverClan cats are able to swim faster than the other Clan cats, WindClan is extremely swift, and ShadowClan excel in stalking, making it good for prey. The book focuses on the politics and other crap that makes the world a horrible place of the Clan cats (bigotry, religious stuff...).
