It’s a pity about Boz Pity! (ARTICLE)

Boz Pity was a planet in the Boz Pity system of the Mid Rim. It was home to the sentient Gargantelle species, noted for their large stature. When the planet was discovered at some point before the end of the Ductavis Era, the Hutts attempted to enslave the species. After the Gargantelles repelled seven invasions and four diplomatic missions, the Hutts convinced the electric caliphs of Boz Pity's neighbor world Mourn to exterminate the species. The Gargantelles were slowly driven to extinction over the next decade, but erected a substantial amount of enormous gravestones to their fallen. When the species disappeared, these monuments earned Boz Pity the nickname "the graveyard planet," which prompted inhabitants of nearby systems to travel to the planet to bury their dead.
