Varl

"The ancestral homeworld of the Hutts, Varl was destroyed thousands of years ago. No accurate record of the planet’s destruction exists, but Hutt mythos suggests that one of Varl’s two suns was pulled into a black hole; according to legend, the resulting cataclysm devastated Varl’s atmosphere and rendered the entire system uninhabitable. Several inconsistencies in the story have led many to suspect that the Hutts themselves were responsible for the planet’s destruction. Regardless, the Hutts fled the ruined planet and–after displacing the native Evocii–resettled on Hutta." ― Star Wars: The Old Republic, Varl codex entry
