Bluefen, a ferret, was the daughter of Bowfleg the Warlord, wife of Swartt Sixclaw, and the mother of Veil Sixclaw. She was described as being quiet and fairly pretty, but was never a strong creature. She was typically ignored by her husband. She stayed out of Swartt's way because she knew of the foul tempers warlords were capable of.
She would later die after giving birth to Veil, as the previous winter had not been kind to her.
