Buyers and Cellars

Walkthrough

 * Speak to Darren Lightfinger in his cellar. The cellar isn't marked as a dungeon on the map, and is accessed through a trap door north of the house.
 * Either listen to his speech or skip it. Ask him what he wants you to do. He will tell you that he needs money, and so you'll be stealing a chalice kept in the Lumbridge castle vault. To do this you will need the key. He tells you to speak to Chief Thief Robin.
 * Robin tells you that he's going to Lumbridge Castle to scout out who has the key and tells you to meet him there.
 * Robin can be found to the south of the castle, inside the main walls. He tells you that the chalice is no longer in the vaults. An "old man with wild hair" took it into the Lumbridge swamp and that you'll need to pickpocket him for the key.
 * Go to Father Urhney's house in the south of the swamp near the copper and tin mine.
 * Try to pickpocket Father Urhney to get the key. You will be told that he is too alert. Speak to him and ask him about the chalice. He won't let you touch it.
 * Go back to Chief Thief Robin and talk to him. He tells you to light a fire outside his house. He gives you a tinderbox to use and now some logs.
 * Light a fire underneath a window and then talk to Father Urhney. Select 'Nice chalice' and then 'Fire! Fire!' You will have a chance to pickpocket him while he's distracted.
 * Open the Display Case. You will take the chalice automatically.
 * Take the chalice back to Darren. Congratulations, the guild can expand, with you as a member. Quest Complete!

Trivia

 * The site update was 14 minutes before the in-game update occurred, however; this wasn't the right one.
 * On the day of release, the quest wasn't released following the system update; as a result, many players were camped out in Lumbridge looking for the quest start when there was none. The update was finally released about 20 minutes later.
 * On the day of release, the spoiler in the knowledge base was concealed by "He may not be the most subtle of rogues, but Darren Lightfinger knows how to keep a secret. He's staying tight-lipped about rewards for the time being."
 * If you click on the quest in an adventurer's log, you will be sent to a page in the knowledge base called "Humble roots", which doesn't exist. This could be an earlier name of the quest, or a serious typo.
 * If your Thieving level is fairly high when you are told to pickpocket the dummy, Lightfingers will be amazed and you can teach him for 2,000 more Thieving experience (plus whatever you earn from pickpocketing the dummy.)
 * While teaching Lightfingers the player will make a Reference to the song of Survivor, "Eye of the Tiger" by talking about the Eye of the Kyatt.
 * Along with this update came a glitch in Lowe's Archery Emporium. where the posters at the wall would disappear revealing a + and a - sign.
 * There is a glitch when in when you ask Darren Lightfingers to try the test dummy again, after picking it, telling him "lets get down to business" will have him explain you still need to steal the chalice, even after the quest and all capers are accomplished.
 * Chief Thief Robin may be a reference to Robin Hood, a fictional character who is famed for stealing from the rich and giving to the poor.
 * Chief Thief Robin seems to be in 2 places at once, at the Lumbridge Castle Grounds and in the Thieves' Guild.
 * Upon completion of the third miniquest, some players experienced problems with their minimaps. Some players also reported that their browser would freeze.
 * While teaching Chief Thief Robin, the "Oum Pa Pa, oh wait, thats the second act." Is a reference to Oliver Twist on broadway.
 * You don't have to use logs just grab his gloves and talk select nice chalice then say fire!fire! then you can steal the key
