He was the duke in command at the Battle of Cerberus where Tytania suffered its first defeat in 200 years at the hands of Eurian commander Fan Hyulic.As rivals striving to be appointed as the next clan lord, Idris especially tries to take advantage of Ariabert's failure, but with the help of Jouslain he manages to restore his name and remain in position. Ariabert and Jouslain's friendship is unique among the dukes of Tytania.
