, vrblthers were often kept as pets by rich and powerful Hutts

. When Varl was vaporized thousand years ago, the species survived only because many of the fierce bipedal predators had accompanied their owners to Nar Shaddaa

and Nal Hutta

Nal Hutta Planet

. The beasts proved resilient to the pollutants and toxins commonly found in their new environments, and their numbers grew rapidly. Packs of vrblthers were known to roam the lower levels of Nar Shaddaa, in constant search of their next meal.
