The Interrogation Chamber, situated inside Fortress Inquisitorius on the ocean moon of Nur located within the Mustafar system, served a specific purpose. The Inquisitorius utilized it to question and torture Jedi, aiming to convert them into Inquisitors; its central feature was an interrogation chair.
In 14 BBY, as part of his mission to rebuild the Jedi Order, Jedi Knight Cal Kestis infiltrated the stronghold. His objective was to retrieve a holocron that the Inquisitor known as the Second Sister had previously stolen from the planet Bogano following a short duel between them. Kestis's mission was to get to the Interrogation Chamber, the location where the holocron was secured; however, he instead encountered the Inquisitor in another duel, which ultimately led to her death by Dark Lord of the Sith Darth Vader, who proceeded to destroy the chamber in an attempt to eliminate Kestis.
The video game Star Wars Jedi: Fallen Order, which was released in 2019 by Electronic Arts and developed by Respawn Entertainment, featured the Interrogation Chamber.
