Prince William of Petra (Guilhem Desiderius Jordanes Léon; born 22 October 1995) is a Sydalene royal, and second child of Desiderius, Prince of Petra and Princess Eirene of Latium. He is fourth in line to the Sydalene throne.

Early life and education

William was born nearly a month premature on 22 October 1995 at St Maria's National Hospital in Aigio, Latium, to parents Desiderius, Prince of Petra and Princess Eirene of Latium. He is the couple's third eldest child and speculated to be named in memory of his mother's former fiancé, Prince Guillaume of Lyncanestria. William was baptized on 19 June 1994 at Sancte Sapientie in the city of Sydalon by Archbishop Hanno Drobeta, christened witt the name "Guilhem Desiderius Jordanes Léon" and bestowed the title "Prince of Petra". His godparents are then Prince Samuel of Lyncanestria (family friend of his mother) and his wife Alys of Aldéon; and Malibar, King of Dakmoor (family friend), and his wife Elizabeth Mutu.

William was primarily raised in Ostracine with his elder sister Melisende, and four younger siblings, Sebastian, Roletus, Desideria, and Bohemond. He also has two younger half-siblings, Maximilian, and Sabine. His family also spent time at a private villa in Pons Veii, and an estate in southern Latium. He has stated that this upbringing has contributed to a close relationship with his siblings. At the time of his birth, William was third in line to the Sydalene throne, as the son of the heir apparent.

William first attended formal schooling at the university level, after being educated by various private tutors throughout his youth. An anonymous, former private tutor once claimed that he was talented, "but focused on making jokes and neglected his lessons". He applied to domestic universities including the Royal University at Veii and Saint Philip's University, along with a number of foreign schools such as Castellum College, Imperial University of Lyncanestria, University of Haenna, Pontifical University of the Holy Trinity, and Saint Mary's University. He reportedly nearly enlisted in the military and enrolled at Academia Militaris Olympia in Latium, but at the last minute decided to enroll at Imperial University of Lyncanestria. He originally enrolled in an economics program, but later changed his focus to history and graduated after five years. While at IUL, William participated in the university's debate club, and intramural football, among other student activities. He recently graduated in spring 2017.

Royal duties

Personal life

William's parents were rumored to have a betrothal agreement in place for William and an unnamed member of the du Caeseti family. The agreement was first reported in 2014, after the agreement had been cancelled and inadvertently leaked to the press, with tabloids claiming there was a "serious rift" between the two families. This leak came following an announcement from the Royal family that William was dating a classmate at Imperial University of Lyncanestria

William speaks a number of languages, and is fluent in Sydalene, Latin, and Outremeri. He holds varying competency in Audonian, and Arthuristan.

He enjoys playing many sports, including football and competitive polo. He is a supporter of Foederati Sydalon AFC, and was often seen at AS Fleury CF matches during university.

Since 2018, he has been courting Marie, Crown Prince of Onneria.
