Kodai was a distant world situated within the Belderone sector, which itself was located in the Outer Rim Territories. This planet is catalogued in galactic legends. Prior to the year 29 BBY, a cataclysmic event resulted in the planet's complete inundation, leaving only the city known as Rena above the waterline.
Kenobi and Skywalker on their mission to Kodai, soon after which Anakin constructed his first lightsaber The Jedi Order strategically used Kodai's vast oceans as a depository for the holocron belonging to the ancient King Adas. The Sith holocron was intentionally placed under immense water pressure, specifically within a deep-sea geyser crater, with the intention to prevent others from succumbing to Adas's influence and the strong allure of the dark side.
In the year 29 BBY, the Jedi, collaborating with Murk Lundi, a Quermian authority on the Sith, successfully retrieved the holocron from its underwater location on Kodai. Obi-Wan Kenobi and Anakin Skywalker then transported the holocron to the Jedi Temple situated on Coruscant, handing it over to Jocasta Nu, the chief archivist, to ensure the secure storage of this hazardous artifact within the Temple's protected archives.
