Brangoire serves as a commanding officer among the Sorcerer-Knights of Cyfandir, loyal to Queen Boudica. His appearance features light skin, dark brown eyes, long black braided hair, a prominent brow ridge, and a large black beard, complemented by a muscular build. He is clad in plated armor, a green cloak, and brown gloves.

He strictly enforces the Order's traditional principles, demanding absolute order and unwavering adherence to protocols. This commitment prioritizes military discipline above civilian considerations during operations like Nemesis hunts. He views actions such as Ocoho breaking formation to protect civilians as insubordination undermining the chain of command.

During the Inquisition's invasion of Cyfandir, Brangoire fights in the kingdom's defense. He intervenes to shield Queen Boudica after Inquisitor Santori incapacitates her, sustaining injuries himself. Later, he collaborates with Seth and Doc to escort the Queen to safety within the Caillte Forest. Following the destruction wrought by the Inquisition, including the death of Yggdrajill (Jill), he joins Queen Boudica and Ocoho to disable the Fantasia Void generator suppressing magical energy. In a critical action, he assists in destroying this device, restoring Fantasia across the land.

After the conflict, Brangoire remains in Cyfandir as part of Queen Boudica's reformed leadership. His experiences during the invasion and exposure to alternative perspectives foster a nuanced shift in his rigidity. While maintaining dedication to the Order, he demonstrates a capacity to recognize the value of balancing authority with empathy, aligning with the kingdom's renewed emphasis on unity between infected and non-infected citizens.
