Jmmaar, a ten-leggedViraanntessemale,[4] was a Jedi Master from the planetVvaw. Sometime before the start of the Clone Wars, Jmmaar and fellow Jedi Master T'chooka D'oon were sent to the planet Kalee to put an end to the Huk War, a conflict that began after the Hukspeciesinvaded Kalee to enslave the native Kaleesh.[1] Through the persuasion of the Galactic RepublicSenate,[5] both Jmmaar and D'oon decided to aid and pledge support for the Huks, which drove the Kaleesh into a state of depression and starvation. As a result of their decision, both Jmmaar and D'oon were disliked in the eyes of the Kaleesh. One of the Kaleesh warlords to witness Jmmaar and D'oon's decision to not help Kalee's inhabitants was Qymaen jai Sheelal. Sheelal, who would later be known as the ConfederatecyborgGeneral Grievous during the Clone Wars, never forgot the two Jedi Masters.[1]
In 20 BBY,[2] Jmmaar,[1] D'oon, and D'oon's Padawan, Flynn Kybo, were dispatched to the planet Vandos to rescue Republic AnxAmbassadorQuiyyen, who had been kidnapped by Grievous.[6] During their mission, both Jmmaar[1] and D'oon were slain by the cyborg General, though D'oon's Padawan found and rescued the captive Quiyyen.[6] As a trophy, Grievous took the fallen Jmmaar's lightsaber[4] and considered it to be one of his favorite weapons. Grievous later utilized Jmmaar's[3]green-bladed[4] weapon during a fight with Jedi Master Obi-Wan Kenobi on the planet Utapau in the final year of the Clone Wars.[3]
Due to his decision to support the Huk, Jmmaar was disliked by the Kaleesh. The Jedi Master's decision eventually led to his death on Vandos, where Jmmaar was killed by Grievous, a former Kaleesh warlord that remembered Jmmaar's actions on Kalee.[1]
