Tyderium

Tyderium was a Lambda-class T-4a shuttle in service to the Galactic Empire during the Galactic Civil War. Darth Vader personally used the shuttle with the intent of transferring Admiral Joser, a traitor who wished to defect to the Rebel Alliance, from the Alpha-Omega Prison to another facility. However, the traitorous Joser was rescued from the prison by a group of Rebels just before Vader could arrive.
