This order was founded by Astyth the Grey, a dwarven warrior, who first fought for women’s right to be soldiers. When no one listened to her words, she cut out her tongue and dedicated herself to training until she won a Grand Proving bare-handed. She eventually became a Paragon at 1:95 Divine after she sacrificed her life for the king.
The women who join this order cut out their own tongues in honor of the sacrifice of Astyth the Grey, the first female Paragon of the warrior caste. The Silent Sisters always keep the knife they use to cut out their tongues, though they never use it as a weapon. Due to the extreme measures one must take to join the order, only a fraction of female warriors become members of this order.
