Kodai

Kodai was a planet in the Outer Rim Territories. Its entire surface was flooded save for the city of Rena.

The Jedi recovered Adas's holocron from Naddists and buried it under tons of water on Kodai, in the hopes that no one else would fall under Adas's influence. It was later taken to the Jedi Temple by Obi-Wan Kenobi and Anakin Skywalker in 29 BBY.
