Landing Platform Thyss was a landing platform in the city of Rwookrrorro on the Wookiee world of Kashyyyk. In 16 ABY, Chewbacca landed the Millennium Falcon there, where it stayed for several weeks in the care of his cousins Jowdrrl and Dryanta. Gawkers from across the planet came to see the legendary starship and have holograms of themselves taken next to it.
