Isaach Castle





In Isaach, we repay our debts.
— Ayra

Isaach (Japanese: イザーク Isaac) is a nation of Jugdral situated in its north-eastern corner, adjoining Silesse and the Yied Desert. It was founded by the Sword Saint Od of the Twelve Crusaders, and its people widely practice a noble warrior culture centered around swordplay.


Isaach's landscape

In Grann 757, Grannvale declared war on Isaach following an assault on the sacred site of Darna, attributed to Isaach's army; in reality, the Darna offensive was solely the work of Isaach's Rivough nobility, whose leader was promptly executed by Isaach's King Mananan for his belligerence. Mananan attempted to negotiate with Grannvale over the situation's reality, head of Rivough's leader in hand, but was assassinated before his news could reach Grannvale's Prince Kurth. In retaliation, Mananan's son Mariccle engaged Grannvale in a full-scale war;[1] knowing of his imminent demise, he tasked his half-sister Ayra with escorting his son Shanan to safety outside Isaach. By Grann 759, Grannvale had won the war and seized Isaach as its own territory, administered by the Grannvale's Dozel noble family under Danan.

Two years later, when Sigurd of Chalphy - branded a traitor by Grannvale - sought to return home to clear his name, he entrusted Shanan and Oifey with the care of his infant son Seliph; accurately guessing that Danan's occupation would not have full control over Isaach yet, he tasked the two with seeking refuge in Isaach's most remote regions,[2] along with other children from their army: Ayra's children Larcei and Ulster, and Lachesis's son Delmud. They settled in Tirnanog, a far-flung village in the northwest of Isaach; some time after the Battle of Belhalla, they were joined by Adean of Jungby and her children, Lana and Lester.[3] During their seventeen years in hiding, Shanan worked quietly to establish a revolution army against Grannvale; in Grann 777, however, Danan finally learned of their presence in Tirnanog and ordered a strike while Shanan and Oifey were out of the country on other errands. In response, Seliph emerged to lead the charge against the Dozel occupation, soon defeating it and freeing Isaach from Grannvale control. Following the liberation war's conclusion, Shanan succeeded the Isaachian throne.

Notable locations in Isaach

Isaach Castle

The capital city of Isaach and the seat of power of its royal family. During the Grannvale occupation, it was held by Johan, Danan's middle son.


Rivough was home to one of the two known noble families of Isaach. Its army was responsible for the assault on Darna, inciting the war with Grannvale; its king was executed by Mananan for this act, and its prince Galzus fled. Following Isaach's defeat, Rivough was occupied by "King" Danan as his seat of power over Isaach as a whole.


Sophara was the home of another Isaach noble family, whose only known scion is Holyn. During the Grannvale occupation, it was held by Johalva, Danan's youngest son.


A remote castle in Isaach's north. In Grannvale's occupation, it was administered by Harold, a general and confidante to Danan.


Main article: Tirnanog

The far-flung village of Tirnanog is located in the remote reaches of Isaach's north-west. Mostly avoiding the scrutiny of Danan's occupation, it was the birthplace of Seliph's revolution.

  1. "Ayra: The leader of Rivough... He's the one who besieged Darna, not my father.
    Quan: You're kidding! Why hasn't Grannvale been informed of that? Prince Kurth would surely reconsider his offensive if he knew that.
    Ayra: My father thought so as well. After executing Rivough's leader, he left for Grannvale's frontline, head and all, to explain everything. However...
    Quan: What?
    Ayra: My father was assassinated at the Grannvalean front. When Isaach heard word of the king's death, the people went into a rage! Mariccle thus proceeded to launch a full-scale attack against Grannvale.
    " — Ayra and Quan, Fire Emblem: Genealogy of the Holy War
  2. "Sigurd: Isaachian territory is just northeast of Lubeck, right? Langobalt's oldest son, Dannan, has been stationed in Isaach ever since their defeat. But I'm willing to bet his authority hasn't reached the outskirts yet. So...
    Oifey: Just a second! Are you suggesting I leave you all and head for safety!? Forget it! I'm not leaving your side, sir! I'm here till the end!
    Sigurd: Oifey, I hate to impose on you, but please understand my situation. I don't want to lose Seliph. He is not even two yet. But I can't fight and take care of him. Oifey, please. I want you to take Seliph and go to where it's safe.
    " — Sigurd and Oifey, Fire Emblem: Genealogy of the Holy War
  3. "Lester: ...So where is mother now?
    Lana: She's working at the convent in Tirnanog
