Rootrock held the rank of General within the Nosaurian rebel forces who were allied with the Confederacy of Independent Systems on New Plympto during the Clone Wars.
In his youth, Rootrock witnessed a Jedi facing off against six raiders in his village. The Jedi implored the raiders to give themselves up, but when they refused, the Jedi swiftly defeated them.
Eventually, he rose to the rank of General among his people. When New Plympto chose to support the Confederacy, due to their pledge to revitalize the rikknit egg market, he commanded his troops against the Republic's military.
Bomo Greenbark encountered Dass Jennir while on patrol, and then he signaled his fellow soldiers to assist him. Soon after Jennir explained the events of Order 66 to Greenbark, Rootrock and his troops apprehended the Jedi. After they got back to their camp, he talked with Greenbark and decided to let the Jedi Master live, because he understood Jennir's predicament. Rootrock gave Jennir a ship so that he could return to Coruscant, on the condition that Jennir would come back to fight against the Imperial occupying forces. He doubted that Jennir would return, but he hoped that the Jedi's sense of honor would motivate him.
Jennir did, in fact, return to New Plympto. The Jedi became a General of the Nosaurian rebellion, along with Rootrock, even though their cause seemed hopeless. General Rootrock was shot and killed by Imperial soldiers during the Cleansing of New Plympto, which was the rebellion's last stand.
