Weapons store shopkeeper

The weapons store shopkeeper owns and runs one of the biggest vintage weapon stores in the Fire Nation. He has the best selection of used weapons and armor for sale. He takes pride in his unique variety of spears, giant axes, maces, and other battle gear. But his most prized weapon for sale is an original Piandao sword. He claims that the story of how he got his sword is incredible, and that if he told anyone, he'd have to kill them.

In "Sokka's Master," Sokka is feeling sad, so Katara cheers him up by going shopping. Team Avatar comes upon his store. Finally, when Sokka seems to have given up the search for the perfect weapon, he spots a gorgeous sword on this wall. At this point, he remarks, "you have a good eye" and proceeds to tell Sokka and the others about Piandao. He also says that Piandao is willing to teach those whom he deems worthy of the way of the sword. This prompts Sokka to train under the sword-master.
