Blitzball

Blitzball was a water sport. In 22 BBY, it was played in a lake on the planet Langston by a group of younglings. Three years later, during the Barsha family's exile to the moon Gus Treta, former Barsha Corporation executive Nnytyl Barsha began fervently watching copious amounts of blitzball played by a regional blitzball circuit.
