From Tiny Acorns

From Tiny Acorns is the first caper Guildmaster Darren Lightfinger will assign a player who has completed the Buyers and Cellars quest. Capers are tasks set by the thieving guildmaster in order to slowly build and fund the Thieves' Guild.

This miniquest requires you to steal a toy dragon made of rubies. Talk to the Guildmaster (Darren) to start.

Walkthrough
After obtaining the caper from Darren, get to Varrock square. Talk to Urist Loric, who is standing by the crafting stall and then the nearby Market guard and ask him every possible question. The guard will tell you about the dwarf being obsessed with his talisman. Now pickpocket the dwarf. Note that it is possible to fail, and if you do you will be hit for 30 damage and will be momentarily stunned.

Stand north of the dwarf, and left-click the talisman to put it on the ground a small distance away (you will automatically walk to do this). Speak to the dwarf, inform him that, "He must have dropped his talisman on the ground." He'll say something along the lines of, "I wondered how that got there!". Click continue and quickly run to the guard, when the dwarf walks to the talisman, right-click and distract the guard (you will tell him about Gypsy Aris giving him the evil eye). When both the guard and dwarf are distracted, quickly steal from the stall. Now talk to the dwarf, to get the bank notes and return it to Darren. Congratulations, miniquest complete!

After completing the caper, Urist Loric sells crafting equipment. It is also possible to steal his craftsman's monocle by telling him that his talisman is at his feet.

 * 1,000 Thieving experience

Trivia

 * The Twitter hint for this update was 'Ruby Dragon!'.
 * Examining the Talisman reveals: "A gem in a gold setting. All craftsdwarfship is of the highest quality." The second sentence is the exact description of a Legendary Artefact quality in the indie game Dwarf Fortress.
 * Examining the Banker's note reveals: "A very large sum of money, sadly not made out to you."
 * Examining the Toy Baby Dragon reveals: "Looks almost as if it could breathe fire...and it can!"
 * The Guard that is supposed to watch the stall of the Craftsman Dwarf will explain that the dwarf "comes from some fortress or other." This too is a reference to the indie game Dwarf Fortress.
 * The name "Urist" itself is a homage to Dwarf Fortress, where the dwarf equivalent of "John" is Urist.
 * The title of the quest 'From Tiny Acorns' is taken from the phrase 'from tiny acorns grow mighty oaks'.
 * If you use the baby dragon or bank notes on Urist, you get a message saying "Why would you give this back to Urist?"
 * If you talk to the Market Guard with the Toy Baby Dragon in your inventory you will say to yourself "I'd better not draw attention to myself right now."
 * If you use the Banker's note on the Market Guard you will say to yourself "I think I'd better not wave this around near him."
 * You used to distract the Market Guard by using Romeo.
