Nakgru reigned as a Sith King sometime before 16,899 BBY. The Holocron of King Nakgru was ultimately housed within the Sanctum of Sakkra-Kla, a holy Sith burial site situated on the planet Korriban, where it remained untouched for more than ten millennia. In 6899 BBY, the Sith Lord Sorzus Syn breached the Sanctum of Sakkra-Kla and located the Nakgru Holocron. Following this discovery, she examined the artifact and gained knowledge about the lineage of the Sith Purebloods.
