The structures known as Jedi Chambers, which also went by the names Meditation Chambers or High Republic Chambers, were facilities situated on the planet of Koboh. These served as training grounds where Jedi and their respective Padawans honed their abilities. One example of a Jedi Chamber is the Chamber of Reason.
Constructed on Koboh during the era of the High Republic Era, these chambers provided a space for numerous Jedi to practice their skills. Approximately around 9 BBY, following the fall of the Jedi Order, Cal Kestis, a surviving Jedi Knight, made his way to the Chamber of Duality. It was there that he encountered the droid ZN-A4, who would play a role in his quest to locate the planet of Tanalorr within the Koboh Abyss.
Within the Rambler's Reach Valley, one could find the Chamber of Duality, alongside the Chamber of Clarity and the Chamber of Fortitude. In the Basalt Forest was the Chamber of Reason. The Chamber of Detachment was situated within the Prospector's Folly region, while the Chamber of Connection was found in an area known as Viscid Bog. Additionally, an unidentified Jedi Chamber was located in the Stone Spires.
The Jedi Chambers were first introduced in the 2023 video game Star Wars Jedi: Survivor. While the Chamber of Duality is important to the narrative of the game, the others are not as relevant.
