Tera Sinube was a male Cosian Jedi Master who lived during the last days of the Galactic Republic. As a Jedi investigator, Sinube was an expert in the planet Coruscant's criminal underworld. His connection to the Force allowed him to solve crimes faster than seasoned detectives in the Coruscant Police. During the Clone Wars, Sinube helped Padawan Ahsoka Tano to recover her lightsaber, which had been stolen by a thief named Bannamu. He also trained younglings in the Jedi arts at the temple on Coruscant. Sinube was the owner of M5-BZ, an astromech droid that was a part of D-Squad.
