Briggs Fortress Arc

⚔️ Villain: Sloth, Kimblee

Introduction

The Briggs Fortress Arc is one of the most important story arcs in Fullmetal Alchemist: Brotherhood. After learning more about the Homunculi’s conspiracy, Edward Elric and Alphonse Elric travel north to the heavily fortified Fort Briggs, where they meet the legendary Major General Olivier Mira Armstrong. Surrounded by harsh winter conditions and constant military threats, the brothers uncover shocking secrets about Amestris while forming new alliances that play a crucial role in the battle against Father.

Story Summary

Following the events surrounding the Homunculi and the growing conspiracy within Amestris, Edward Elric travels to Fort Briggs, the northern fortress that protects the country’s border from neighboring Drachma. The fortress is commanded by Major General Olivier Mira Armstrong, the fearless older sister of Alex Louis Armstrong.

Initially suspicious of Edward and the military’s motives, Olivier quickly proves herself to be an intelligent and ruthless leader who values strength, loyalty, and honesty above rank. After learning about the Homunculi and Father’s secret plans, she quietly begins preparing Briggs for the conflict she knows is coming.

Meanwhile, deep beneath Fort Briggs, Edward discovers Sloth, one of the Homunculi, digging a massive underground tunnel as part of Father’s nationwide transmutation circle. Although Sloth possesses incredible physical strength, Briggs’ soldiers manage to contain him through teamwork and Olivier’s leadership before he eventually escapes.

At the same time, Solf J. Kimblee, the Crimson Alchemist, arrives in the north under orders from Central Command. Kimblee is assigned to capture Scar and monitor Edward while secretly advancing Father’s plans. Unlike many military officers, Kimblee fully embraces destruction and becomes one of Edward’s most dangerous human enemies.

Elsewhere, Scar, accompanied by May Chang, continues researching his late brother’s alchemical notes. Their investigation gradually reveals the true history of Amestris, Xerxes, and the nationwide transmutation circle designed by Father.

As tensions increase, Edward reluctantly cooperates with Kimblee to avoid exposing his own plans while secretly helping Scar and the resistance whenever possible. Olivier also travels to Central, where she confronts high-ranking officials and begins gathering intelligence on the military conspiracy.

The arc reaches its climax when Father strengthens his control over Central, while Kimblee prepares the northern region for the events of the Promised Day. By the end of the arc, the heroes understand that the entire nation of Amestris has been turned into a giant transmutation circle, setting the stage for the final battle.
