The Brothers of Stone as they appear in The Daughter.
The Brothers of Stone were a religious group of male humans, pledging themselves to whatever the earth produced, including gold. For some reason they kept those who would eventually become the Sisters and the Sons imprisoned in an underground hall, but culling their husbands and daughters.
One day, Elosha, Fuerst and their raiders assaulted their temple, killing all the brothers in their way and freed the Sisters and Sons.
20 years later, the remaining Brothers of Stone arrived at the new village of the Sisters, seeking revenge. However, the Sisters were guided by a bunny deity to drink water from the well of the hall in which they were gathered, eventually giving them magical powers so they could defeat the attacking Brothers of Stone.
