“I hereby sentence you to death for your acts of treason. No visits to the king today, Sigurd.”
—Arvis during the prelude of the Battle of Belhalla
The Battle of Belhalla, also known as the Belhalla Massacre, is an event at the end of Chapter 5 of Fire Emblem: Genealogy of the Holy War, occurring in Gran Calendar Year 761. It is the final event in Sigurd's tale, and it is planned by Arvis in order to remove all obstacles in his plan to unify the whole continent.
The forlorn prelude of the Battle of Belhalla starts after Reptor of Freege is defeated, when Sigurd confronts Arvis’s confidant General Aida in Velthomer. Aida says that Arvis knew that Sigurd was innocent all along, and that the Royal Guard that Arvis leads has prepared a celebration for Sigurd’s army near Belhalla.
Sigurd suspects nothing, and goes to Belhalla, and after Sigurd talks with Arvis for a little while about King Azmur, Arvis decides to cut him off, and tells him that he is still considered a traitor guilty of killing Prince Kurth (even though he and his father Vylon, who was also blamed, were innocent). Arvis then brings Deirdre out long enough only for Sigurd to be in shock and for Deirdre to suspect that she knows Sigurd (she had her memories of him erased during Chapter 3). Arvis then kills Sigurd with Valflame. Sigurd’s army is bombarded by a storm of meteors cast by the Roten Ritter, and they are surrounded by the Royal Guard, but some of his army manages to escape.
Regarding those who died at the Battle of Belhalla, here is what is known aside of Sigurd's death:
- Quan and Ethlyn died in the Yied Desert during Travant’s ambush, which is known as the Yied Massacre, occurring just a short while earlier than the Battle of Belhalla;
- Lewyn was killed by Manfroy, but was later revived by Forseti.
- Finn did not die because he was in Leonster at the time of the Battle of Belhalla,
- Deirdre did not die because she was brainwashed by Manfroy in order to have Arvis take her for his wife. She would die some years later at the hands of a Loptyr-possessed Julius.
- Ferry, Tailto, Raquesis, Adean, Sylvia, and Briggid are known to have survived, as they either are known to have had children afterward or were seen afterward. This means that Ayra was the only playable mother at the Battle who could've died. It is unknown whether Ayra was dead or alive at the ending of Genealogy of the Holy War.
- By the time of Seliph's tale, Ferry and Tailto had died. Ferry, the Queen of Silesse according to Thracia 776 and the manga, died of an unspecified illness. Meanwhile, Tailto died of illness and depression after years of being forced to live in the Freege castle and enduring abuse from her sister-in-law Hilda; her health took a big hit for protecting her daughter, Teeny, from Hilda's abuse, making sure that the girl would not be physically attacked, instead taking the abuse herself.
- Around the time of Seliph's tale, Adean had become an abbess and was conducting church services in Isaach; Briggid lost her memories and became Eyvel, who was Leif, Nanna, and Mareeta's caretaker; Raquesis left Leonster to try to search for her son Delmud and disappeared in the Yied Desert; and Sylvia's whereabouts are unknown. One scrapped possibility is that Raquesis and Sylvia were captured by the Lopto Sect and turned to stone by Veld.
The army of Sigurd, all of whom that lived or died, were branded as traitors, and it is hinted in Fire Emblem: Thracia 776 that those captured were turned into stone by Veld, as it is stated by August that the stone statues in the Yied Shrine included "the captives of the war in Belhalla from a decade ago".
The Battle of Belhalla is one of few times in the Fire Emblem series where a main character (but not an antagonist) is canonically killed. Other examples include Ninian in Fire Emblem: Rekka no Ken, Hector in Fire Emblem: Binding Blade and Azura in Fire Emblem: Fates. The Battle of Belhalla is, however, the only time when a main Lord of a given game is canonically killed.
