Arno, the King, was a Zeltron male and the husband of Leonie. This Zeltron was the royal leader of Zeltros during the era of the Galactic Civil War.
Like all of Zeltros' rulers, Arno was selected by the Zeltron people because of his abilities in the areas of combat, artistic expression, scientific knowledge, and love. Arno possessed a great deal of charisma and intelligence, and he understood that those who were not Zeltrons frequently held incorrect ideas about his species. He was an avid collector of art, especially erotic poetry, of which he had a substantial collection. He was proficient in various forms of entertainment, including poetry recitation, acrobatics, therapeutic massage, and playing the Zeltron lute. He also derived great pleasure from parties.
Arno and Leonie held a party for representatives of the Alliance of Free Planets in 4 ABY, not long after the Battle of Endor. Regrettably, this happy event was disturbed by the Nagai, the Hiromi, and the Tofs when they launched invasions.
The characters of King Arno were brought to life by Mary Jo Duffy and Cynthia Martin.
