Brian is a dutiful man, he wished to become a knight one day, as he believed they are courageous and noble, protectors of the weak and fighters with injustice. Thus, he felt disgust when Fierce Scar offered a knight title for grain burning.
He was proud to become a patrol captain, believing other patrolmen admitted his merits, only to discover later that others simply avoided captain's duty to ignite beacon during the Months of Demons.
Brian was born in a hunter family. Due to his own abilities, he became a patrol captain. Every winter he and Greyhound had stayed in the Beacon Tower of the North Slope Mine area, and whenever they saw a great number of demonic beasts crossing over, they had lighted the beacon to warn the townsfolk of their coming.
When Brian was a child, he discovered abandoned well connected to the castle garden. For this he was beaten and prohibited to enter ever again.
Brian and Greyhound were called to prince Roland and answered his questions about Months of Demons and demonic beasts. He was excited, seeing this as opportunity to be noticed and promoted, believing he would be chosen to protect a new wall from the beasts. To his surprise abd disappointment, he didn't pass chief knight's check and wondered how prince intended to fight beasts with commoners.
Brian witnessed Greyhound's death by hands of patrol plotters led by Fierce Scar. The latter conspired all patrol team, promising knight title and other rewards for burning food reserves. Under the threat of death Brian led plotters to the tunnel connecting with castle's garden. When they reached basement, he escaped from the group and fought them with Nightingale's help. When he woke up, healed by Nana, he was praised by Roland and promised to become a knight.
After long hours of training Brian became a confident swordsman, capable to overcome several clumsy patrolmen.
