Jmmaar was a male Viraanntesse Jedi Master from the planet Vvaw. Prior to the Clone Wars, Jmmaar and fellow Jedi Master T'chooka D'oon were sent to the planet Kalee to resolve the Huk War—fought between Kalee's native Kaleesh and the invading Huk species—and supported the Huk, a decision that placed the Kaleesh in a state of destitution. One of the Kaleesh warlords who witnessed the Jedi's decision to not help them was Qymaen jai Sheelal, who, during the Clone Wars, was known as the Confederate cyborg General Grievous. In 20 BBY, on the planet Vandos, Jmmaar and D'oon were slain by the cyborg general when the two Jedi arrived on Vandos to rescue Anx Ambassador Quiyyen from Grievous.
