Tengrove was a Jedi Master and the Watchman of Kiffu's sector around the time of the Great Galactic War. A year before the Annexation of Kiffu, in which the Sith Empire forcibly took control of the Kiffar homeworld, Tengrove discovered the Force-sensitive Kiffar Shigar Konshi and took him to be trained as a Jedi. Konshi went on to be the Padawan of Grand Master Satele Shan.
