Casiss was a male Felucian who was the elder of a nysillin farming village on Felucia. During the Clone Wars, his village was threatened by the Ohnaka Gang who wanted a portion of the nysillin. Casiss hired four bounty hunters – Sugi, Embo, Rumi Paramita and Seripas – to fight the pirates, when a group of Jedi – Obi-Wan Kenobi, Anakin Skywalker and Ahsoka Tano – also came and agreed to help. After helping the villagers learn how to fight and defeat the Ohnaka Gang, Casiss thanked the Jedi and bounty hunters before setting off to oversee the rebuilding of the village.
