This is the famous Thieves' Circle! I thought you would've known this, seeing's how you made it through all the defenses and whatnot. But no matter. You're quite promising, and the Circle could use someone like you.”— Loxley.
The Thieves' Guild or Thieves' Circle is a group of thieves in the Hub's Old Town led by the slightly crazed Loxley. Their main hideout, the Thieves' Circle, can be found in the basement of a junkie's home. An audience with Loxley and his associates will require the player character to lockpick and survive some minor traps. The guild is loosely based on the 'old stories' as Loxley calls them of Robin Hood and his band of merry men.
The leader of the guild is Loxley, who has his own room and three other members in the hideout: Jasmine, Cleo and Smitty. Jasmine is Loxley's assistant who handles all the details of assignments and payment. Cleo is the only member who seems less reluctant about communication. She will give a great deal of information on the Guild and how they feel about the rest of the Hub. Smitty will not have much to say - he actually seems pissed off about even surviving.
The guild, if the Vault Dweller is accepting, possesses a quest to steal a diamond necklace from Daren Hightower in the Heights. If successful, the Vault Dweller will be rewarded with some bottle caps and an electronic lock pick, which is very useful for breaking into the Mariposa Military Base. Jasmine tells the player not to kill Mr. Hightower, but if he is killed, the player will be rewarded just the same.
