Troda 9 is a planet that no one has been to.
It is said that Troda 9 is where minerals are mined to create Disks. Slizers once lived there but they died out and the ones on the Slizer Planet never knew about them. It was inside of the Broga System.
No one knows what the planet is like since it has never been visited. It was rumored to have aliens on it. It was thought that it was destroyed when the Meteorite was heading for the Slizer Planet and hit Troda 9. Snipe currently resides there in secret.
