The Sanctum of Sakkra-Kla was an ancient sacred tomb on planet Korriban. It contained the Holocron of King Nakgru, various alchemic scrolls and the preserved body of a terentatek.
The tomb had lain undisturbed for more than ten thousand years when Sorzus Syn pillaged it with a few Sith slaves in 6899 BBY. It was protected by packs of tuk'ata and the antechamber contained stone gargoyles that would turn to life in the presence of intruders.
