Logor was a Quarren male criminal residing on the planet of Mon Calamari. In the era of the Galactic Civil War, operatives from Imperial Intelligence journeyed to Morjanssik, a city on Mon Calamari. Their mission was to sabotage the mining activities within the city, with the intention of hindering Mon Calamari's ability to provide starships for the Alliance to Restore the Republic. These agents, masked as Mon Calamari, enlisted Logor's services to assault an Alliance team dispatched to Morjanssik to probe the sabotage instigated by the infiltrators. Logor then recruited a band of Quarren criminals from the area to ambush the Alliance agents at the Long Drink, a local bar in Morjanssik. Logor was there during the conflict, but he took advantage of the chaos to make his escape. He sped away on a skimmer, leading to a chase by the Alliance agents.
