Zilbo III was the fourteenth and final king of the Entharion Dynasty. He came to the throne of Quendr in 628 GUE, after Mumbo II. He was succeeded by Duncanthrax the Bellicose, the first king of the Flathead Dynasty, on the last day of 659 GUE. Little is known about what became of Zilbo. Some say he was killed during the palace revolt, or simply died from too much reveling while celebrating the upcoming New Year. There is evidence that he was exiled to a Mithican villa, where he invented the card game Double Fanucci.
