Grotthu

"The slaves. a rabble of mixed species, are collectively scorned with the epithet Grotthu. After experiencing the artifice of the Republic's slave bans, it's refreshing to see the weakness of inferiors affirmed and exploited for gain!"

- Sorzus Syn

The Grotthu were a mixed-species group of slaves that were the lowest caste in the society of the Sith Purebloods, a sentient species that resided within the Stygian Caldera.
