Gru was a Chortose who worked at Agricultural Hub 42 on Chortose during the High Republic Era. He was the sibling of Pango, who also served at the factory. When the Nihil marauders attacked Agricultural Hub 42 in order to acquire the that the facility utilized, Pango attempted to signal the Jedi Order, but Gru felt that it was futile, telling his brother that they had to defend the factory themselves. When the Nihil entered the facility, the marauders shot and injured Gru, intending to kill both Chortose and steal the droids. However, the Jedi Knight Keeve Trennis and Wayseeker Orla Jareni, in turn, arrived to defeat the Nihil, saving the Chortose and the factory.
