Grigor served as the Imperial Governor of the world M'haeli in the year 0 ABY; he was a human male.
This governor was a dishonest individual who established his own unlawful dragite mining venture on the planet, and Grigor swapped out the stormtroopers reporting to him for pirates who were loyal only to himself. He was known to have suppressed the native H'drachi, and he also destroyed at least one Rebel cell using a stormtrooper attack.
To conceal these actions, Grigor colluded with Ambassador Jollie, but he then became conscious of Grand Moff Lynch Hauser's growing suspicions about his deeds. In an attempt to gain acceptance from the local residents, he took 'Queen' Mora captive, who was a member of the previous M'haeli Human royal family, and announced his plans to wed her. Grigor's life ended during the Battle of Red Rock, subsequent to his apprehension by Imperial officer Ranulf Trommer, dispatched by Grand Moff Lynch to look into the matter. With his life in tatters, he tried to flee, using Mora as a hostage. However, Ranulf delivered a quick kick, which turned the blaster toward Grigor's own head, where it then discharged, resulting in his immediate death.
