The Deference was a Pythar-class Imperial shuttlecraft that belonged to a scientist of the Sith Empire during the Great Galactic War between the Empire and the Galactic Republic. In 3665 BBY, the Deference was shot down during the Battle of Hoth and crashed into the icy surface of the planet Hoth, and the shuttle remained buried in a cave system for decades. During the subsequent Galactic War between the Empire and the Republic, the Deference was the subject of a Jedi mission to recover information from the shuttle's databanks.
