After completing the Buyers and Cellars quest, the player can access a small version of the guild. The guild can be expanded by doing a series of miniquests called capers; there are currently three. To start a caper, talk to Guildmaster Darren Lightfinger. Completing each caper will result in a larger version of the guild with more activities to do in it, athieving experience reward, and other rewards. The current capers are:
- From Tiny Acorns
- Lost Her Marbles
- A Guild of Our Own
After the last part is complete, you can talk to the Guildmaster and ask to use the dummy again. After you offer to show him your tricks you will gain another 2,000 exp.
From Tiny Acorns
Darren again enlists his fellow guild member, the adventurer, on another caper to expand the guild and raise more money. He is paying for a toy dragon made of rubies to be made by Urist Loric, yet is scamming him to make more money for the guild’s expansion. He asks the adventurer to steal the toy and then ask the dwarf to give Darren his money back due to no product being available for Darren. After talking to the local guard, the player finds out the dwarf is obsessed with his strange talisman. The player drops the dwarf’s talisman, and being obsessed with it, the dwarf moves away from the stall to grab it. After swiftly distracting the guard, the player runs over to the dwarf’s stall and steals the toy. As part of the scam, demanding the money from the dwarf and giving it to the guild, Darren manages to expand the guild’s training facilities. Volunteers and more thieving masters move in, and another area is constructed. Also, the dwarf opens a new stall selling crafting equipment.
Lost Her Marbles
Darren seeks to expand the guild more, still not seeing its full potential. He hears that a magician blew herself up in a scientific explosion, turning herself into pure crystal fire, and that the blast radius was massive. The magic in these expensive crystallized flame fragments is worth loads of money, and people are searching for them. He asks the player to find all 32 fragments before others do. He informs that people around RuneScape have found these and picked them up, and the player must steal it from them. The player searches far and wide, in Al Kharid, the H.A.M. Hideout, the Rogue’s Castle in the north Wilderness, and even north of Ardougne. After stealing up to 6 flame crystals from each of the groups, the player returns them to Darren, in 4 sets of 8. He sells them, gives the player a share, and pays for more expansion. A new thieving supply store opens up, more people move in, and more buildings are made. The player also becomes more skilled at Thieving.
A Guild of Our Own
Darren wants the guild to be registered as an official guild so that they get funding and full benefits. He also wants the expensive bonds that are located in the registration office. He enlists the now heavily trusted player on anothercaper to use trickery, theft, or whatever skills necessary to register the guild as official. The player makes a Vial of stench, which makes people unable to clearly see the person holding it, under Darren’s orders. The player travels toArdougne to visit the Registrar. After stealing her key, the player uses it to gain access to a room to distract her. The player then swiftly blackjacks the guard in the room to obtain a vault key and runs to the trapdoor. The player enters the vault room. After picking the lock on the gates and passing traps, the player steals bonds from the vault. The player then talks to the Registar again to get the guild registered. With the money from Registration and the bonds, Darren manages to complete the Thieves’ Guild. A new bank opens, more buildings are constructed and the final npcs needed in the guild move in.RS thieves' guild Capers,
