Kruluk was a male Quarren who lived during the Galactic Civil War. Kruluk resided in the city Morjanssik on the planet Mon Calamari, where he worked as a bartender in the Long Drink, a local bar. Kruluk was good-natured and talkative, and he tried to keep himself from getting involved in any trouble, so he preferred not to get security officers involved in any altercations that took place in his bar.
