Kalkovak, a distant planet, served as home to diverse species, notably the Quarren who inhabited a significant area. Functioning as a port of call, it catered to those journeying towards the Outer Rim Territories. After becoming an annoyance to his travel companions, Illyan Webble found himself abandoned on this world. On one occasion, Han Solo and Lando Calrissian visited this planet often, seeking Webble and the knowledge he possessed regarding the location of the Yavin Vassilika.
