Varl/Legends

Varl was the original homeworld of the Hutts and t'landa Til. According to Hutt legend, it was devastated in a cataclysm that tore away its atmosphere and obliterated the rest of the planets within its star system.

The Cataclysm
According to Hutt legend, the planet Varl orbited around two suns, Evona and Ardos. Evona and Ardos were venerated as gods by the Hutts. Evona was consumed by a black hole, and in fury, Ardos expelled its gaseous external layers and destroyed the other planets of the star system.

Somehow, Varl survived, though its atmosphere was torn away and its biosphere devastated, and left as wasteland with acid rain. The Hutts, too, survived the cataclysm, and soon left the pockmarked world. They believed that by surviving the cataclysm they had been elevated to the status of 'near-gods'. The planet they left behind was inhabited by the descendants of abandoned servants of the Hutts, with only a few few squallid manufacturing centers.

Speculation
The tale has generally been dismissed as more Huttese hyperbole, and the most commonly accepted alternate theory is that the Hutts destroyed their world themselves, in some ancient war. Interestingly, there are signs indicating that the cratered wasteland of planet Varl was once a pleasant green world, and besides many asteroids, no other world orbits the white dwarf, Ardos.
