Sister Beatrix
Sister Beatrix is one of the first members of the Order of Twilight, founded by Grand Master Francis. She is responsible for the daily care of the Anvil Squad's wounds, along with her young novice, Clara. Like the rest of her Sisters, she received training in the use of repeating crossbows, throwing knives, hand-to-hand combat with and without daggers, and also in hardening and launching her wing feathers like steel projectiles as a last resort in a fight (these regenerate after a while, like real birds).
