“My daughter, I regret that I could not do more for you. When you were stolen away to the Kingdom, when the prime minister did those horrible things, I could only watch in horror.”
—Ionius IX to Edelgard

Ionius IX is a character in Fire Emblem: Three Houses and Fire Emblem Warriors: Three Hopes. He is the Emperor of the Adrestian Empire in Imperial Year 1180 and the father of Edelgard.


Three Houses[]

Ionius IX was crowned sometime before Imperial Year 1162, when his daughter and future heir Edelgard was born to his consort Anselma, the sister of Lord Volkhard von Arundel. He fathered a total of eleven children, though Edelgard was one of the few who bore the Crest of Seiros.

During his reign, Emperor Ionius attempted to consolidate power in the hands of the throne. However, The Seven Houses put a stop to that, and Ionius lost the ensuing power struggle resulting in the Insurrection of the Seven spearheaded by Ludwig Von Aegir and Volkhard in 1171, a coup d'état which stripped him of most of his power. Amidst the upheaval, Edelgard and Anselma were taken to the Holy Kingdom of Faerghus in apparent exile by Anselma's brother, Lord Volkhard, who was also one of the key conspirators. Anselma, who was called Patricia in Faerghus, later married King Lambert of Faerghus, and stayed behind in the Kingdom when Volkhard and Edelgard returned to the Empire in 1174.

By then, Ionius IX had become little more than a political puppet for Ludwig. Powerless, he could only watch in bitter silence as the Adrestian nobles and Those Who Slither in the Dark conducted torturous Crest experiments on his children in an effort to create the perfect ruler for the Empire. Only Edelgard survived the ordeal and bore a second crest as a result, the Crest of Flames.

Ionius IX remained emperor until 1180. After spending much of the year studying at the Garreg Mach Monastery Officers Academy, Edelgard returned to Enbarr to visit her father at the Imperial Palace and demand the crown from him. She may or may not have Byleth accompany her and bear witness to the succession, a role traditionally filled by the archbishop of the Church of Seiros. Feeble and near death, Ionius IX gratefully complied with his daughter's plea to relieve him of the heavy burden of rule and abdicated in a brief ritual. Ludwig then arrived in the throne room and was promptly relieved of his duties as prime minister by the newly-crowned Emperor Edelgard von Hresvelg.

Edelgard later revoked Ludwig's title and confiscated his lands (or passed them onto his son, Ferdinand, on Crimson Flower), restoring the emperor's power. The other conspirators of the Insurrection of the Seven were similarly punished for their crimes. Ionius IX presumably passed away between the coronation and 1185.

Three Hopes[]

Ionius only appears in a brief cameo, in which he has a single line of dialogue in Scarlet Blaze's first chapter. He passes away after abdicating rule of the Empire to Edelgard.


In the years prior to the events of Three Houses, Ionius IX was a bold individual, fathering eleven children to various mothers as he sought to consolidate as much of the Empire government's power for himself. However, following the Insurrection of the Seven and other dark events, he became chastened, as all power was stripped from him by the court and the members of his family were lost or taken from him. The stress of his later life took a sharp toll on him, leaving him a sickly and downtrodden man who willingly gave up his position as Emperor to Edelgard when the time came.

Ionius is a variant of the ancient Greek name Ionis, which has origins in the Hebrew Yochanan, meaning "God is gracious". The common name John shares the same etymology, being one of the variants of this Hebrew name.

Ionius was the full name of a late Roman Jurist known as Ionius Apollonius.

Ionius' surname Hresvelg comes from a Norse mythology called Hræsvelgr (Old Norse "Corpse Swallower"), a giant who takes the form of an eagle.


  • Ionius shares his voice actor, Paul St. Peter, with Gregor from Awakening.
  • The chair Ionius sits on is actually part of his model. Should one try to make a character use his model through hacks, they will have the chair appear behind them clipping through their legs.
