Bri was born in the town of Lockhaven. Before she was drafted into the Mouseguard, she was a great weaver. Bri also generously made clothes for orphans she had found on the street, making sure they could at least be warm for the winter. She will also occasionally hand them a bit of cheese. Bri is a very resourceful mouse who saves for the cold, harsh winter. Once in combat, her combative personality makes her eager to fight. In normal life Bri is fearful of common predators, in combat it is the opposite story where she runs at them in battle-lust.
