Chozz Wardle served as the royal physician for the House of Lorac located on the planet of Velmor. Upon Prince Denid's arrival back to his homeworld in 3 ABY, following almost two decades of exile, it was Wardle who confirmed that he was who he claimed to be. Despite knowing that the current regent, Zelor, would not be happy with this discovery, he announced to the royal court that Denid was indeed the missing son of King Lorac. Wardle also included in his official report that he believed Denid would be a suitable king. Not long after submitting his report confirming Denid's identity, Wardle and all of his employees were executed by Zelor.
The first appearance of Chozz Wardle was in Star Wars (1977) 49, which was penned by Mike W. Barr and published in 1981. Walter Simonson provided the illustrations of Wardle in the comic book. While Wardle's identity was not explicitly stated in his initial appearance, his name was revealed in the Wizards of the Coast article titled Velmor: Royalty and Rebellion in 2003.
