Jahn was a male Zeltron, who, along with three other Zeltrons—Bahb, Marruc and Rahuhl, volunteered to be attaché to Princess Leia Organa in 4 ABY. Despite Leia’s dislike of Zeltrons, Admiral Gial Ackbar felt it was essential to assign the boys to her in order to retain diplomatic ties to their homeworld. Jahn and the other Zeltrons were delighted to work with Leia, of whom they’d heard many stories, and well as Han Solo—although they initially mistook him for Lando Calrissian.
