Renso was a Saiyan male Jedi Master of the Jedi Order who served as Battlemaster and head of security at the Coruscant Jedi Temple during the waning days of the Galactic Republic.
In 32 BBY, during the Naboo Crisis, Renso sought refuge on his homeworld of Sadala where he discovered a young slave boy named Cabba. He took the young boy to the Jedi Temple on Coruscant where he would be trained.
He met his doom at the hands of Darth Vader during Operation: Knightfall, when the Order 66 go-ahead was given.
