The Jedi Temple, situated on Kordoku, served as a repository of galactic history, possessing a unique artifact that granted temporal displacement to its user, enabling journeys across various eras of time. Around or after 35 ABY, Rey Skywalker, guided by the ancient Jedi texts, journeyed to the temple during the Life Day celebration. Her mission was to employ the key to the galaxy's past, aiming to illuminate a Jedi's path forward. Upon entering the temple, she skillfully employed the Force to extract the key from its hidden location and subsequently activated it.
