Dreypa's Oubliette

Dreypa's Oubliette was an oubliette affiliated with the Sith Lord Dreypha and in the possession of Pulsipher in 3,963 BBY. Presumably, a being inside the Oubliette would endure the agony of a living death as long as one resided within it, even to the point of the galaxy's collapse. In addition, no sensor could penetrate the oubliette to find the existence of any being residing within. Pulsipher used the Oubliette as a threat towards Zayne Carrick in order for him to reveal the secrets of the Muur Talisman.
