A Mon Calamari navigator named Ishel, a male, was part of mercenary leader Brigadier Jarrow Rusher's crew, serving on the flagship Diligence in 1032 BBY during the era of the Republic Dark Age. After the Battle of Gazzari, the Diligence departed Gazzari, carrying 1,700 students and the Jedi Knight Kerra Holt as passengers. On their voyage to Byllura, Rusher inquired with Ishel about the possibility of reaching the Galactic Republic. Due to the shutdown of the hyperspace relays, the Mon Calamari was unable to locate dependable hyperspace routes to Republic Space, which resulted in the Diligence being compelled to travel to Byllura instead. At that location, Kerra and Rusher were instrumental in toppling the Dyarchy, the local Sith government. It is believed that he later participated in the Battle of Byllura and the Siege of Calimondretta.
