Crevasse City, the primary city and capital of the planet Kalkovak, functioned as a key port for spacers heading towards the Outer Rim Territories. In the past, Han Solo and Lando Calrissian conducted a search within its boundaries for Illyan Webble, as he possessed knowledge regarding the whereabouts of the Yavin Vassilika. Their search proved fruitless, as they discovered he had already left for Mon Calamari as a stowaway. Furthermore, a Quarren settlement existed within the city, residing in what was known as the Quarren Sector.
