Bloodlines Game Info: Group Names

Why is it some bloodlines groups are called clans while others are packs, hordes, or guilds?  There is actually a specific reason for the different names.  It all comes down to the leader of the group. 

If the leader is pure vampire it is called a CLAN.

If the leader is pure lycan it is called a PACK.

If the leader is a hybrid it is a HORDE.

If the leader is a human it is a GUILD.  (If you are in a group with a human as a leader you should just call it quits and find another game, seriously, imho. )

Please note: no matter what the leader's choice of RP is, any Bloodlines player can join any Bloodlines group. A vampire can join a guild, etc.  unless the leader specifically states "we only want this race". Our king, Darrell Mistwallow, was a hybrid at one time but is now a pure vampire once again.  Thus, we are a CLAN.
