I had me a dream once. Just after I *acquired* this here knife. Only the knife was a bit shinier and I was in an alley somewhere. I dunno, maybe it was Brie or Holsten, someplace like that. Anyways, I'm walking down this alley when I comes across some dumb bloke trying to shortcut his way to market. Like *my* alley is a god-d**ned thoroughfare for just anyone!
In addition to the Thieves' Guilds, there is a hierarchy that all thieves are part of. Rank is based on skill, and can be raised or lowered at any time. The Queen of Thieves, the greatest living thief in the world, is the ruler. Guildmasters answer only to her, and she answers to no one at all.
