"About a century ago, an entrepreneur cyberformed the Tytun Four moon into an enormous databank designed to listen and record. It was operated by droids and protected by mercenary contract. Like all archives, it ran out of space. Thus, the Tytun Rings--a fleet of wrecked starships salvaged for the purpose of data storage. They orbit the moon, still recording, still protected by the mercenaries."
―Watcher Three[src]

The Tytun Rings was a fleet of wrecked starships that orbited the moon Tytun Four, acting as a massive data storage unit for the cyberformed moon's recording activities.
