Daryun, a former Marzbān and Cavalry General of Pars, stands as a paragon of martial skill and steadfast loyalty. Renowned as "the knight among knights" and "fierce tiger general" by age 27, his battlefield acumen and rigid discipline earned him legendary status. His military career under King Andragoras III faltered when his strategic dissent during the Lusitanian invasion led to demotion and Pars’ defeat at Atropatene. Charged by his uncle Vahriz to safeguard Prince Arslan, Daryun embraced this mission with unyielding dedication.

His allegiance to Arslan shifted from duty to profound personal devotion, inspired by the prince’s empathy and leadership. Daryun fiercely guards Arslan’s life, vowing retribution against any threat. Though stern, he adheres to an unbreakable code—sparing unarmed adversaries and showing unwavering kindness to allies, traits observed by companions like Farangis. His rapport with strategist Narsus, a childhood friend, blends sharp wit with deep mutual respect rooted in shared history.

Orphaned in youth, Daryun’s upbringing under Vahriz instilled a profound sense of duty. Vahriz’s death at Silvermask’s hands (Hilmes) steeled his resolve to shield Arslan and avenge his uncle. Transitioning from a rank-bound warrior to a trusted advisor, Daryun ascended to Ērān of Pars following Arslan’s coronation, succeeding Kishward.

A master of spear, sword, and bow, Daryun’s combat style marries lethal precision with battlefield pragmatism. His signature spear technique—catapulting enemies through the air—exemplifies both raw power and tactical brilliance. Mounted on his warhorse Shabrang, their symbiotic bond becomes a battlefield legend.

Daryun’s journey traces his evolution from a disciplined soldier to a leader harmonizing martial mastery with strategic insight. As Arslan’s protector and mentor, he navigates the prince through political intrigue and personal trials, embodying the ideals of honor and service that define Pars’ legacy.
