A holocron created by the Sith Lord Tulak Hord was buried in the Tomb of Marka Ragnos on the planet Korriban, in the Valley of the Sith Lords. Despite dozens of attempts to retrieve the holocron from the pyramid in which it was stored, the Holocron was never found until over a millennia after its burial. This was until a former slave managed to retrieve the artifact.
