In 1000 BBY, Darth Bane found Nadd's holocron within a locked room inside Nadd's tomb on Dxun. From the holocron, Bane learned of the parasitic orbalisks that infested the chamber (and later his body). He also found within the holocron ancient spells for conjuring Sith magic. Bane later transcribed the spells and presented the transcript to his apprentice, Darth Zannah.
