This sepulcher served as the ultimate memorial for the preserved body of Sith King Dathka Graush, following his murder in 6950 BBY. Graush governed with fear and brutality for half a century, generating a vast number of dead bodies. He then utilized these corpses in experiments involving Sith magic and alchemy, resulting in the creation of a zombie army. During his lifetime, Graush had substituted his biological heart with a dark side Force-sensitive crystal. Post-mortem, this crystal was employed to ensnare the essences of his zombies. The aforementioned crystal was interred alongside Graush's corpse, and the zombies remained inactive until a sentient being made contact with the Heart.
