Master Piandao was a Jedi Master renowned for his skill in lightsaber dueling. He was born on Tatooine, and spent his childhood there. His father manufactured vibroblades, and due to their location, often sold them to pirates and others of the criminal type. However, his skills as a weapon manufacteror were recogized, and the family moved to Coruscant and made the business legitimate. It was after their move that their young son's Force sensitivity was discovered, and he was sent to live at the temple to train as a Jedi.
Master Piandao later trained the Jedi Padawan Tem. The pair's most notable mission was when they were sent to Tatooine to take out a Pirate base.
