Martin d'Astora

Martin d’Astora is the "many times great-grandfather" of Claire and Sophie. He was the younger brother of Queen Estelle. Because of what his sister had done to the last unicorn, he fled Arden and changed his last name to Martinson. He tuned his older sister Queen Estelle d'Astora to stone to save her from becoming a wraith, and to give her time to find a antidote. He was the grandfather of Diana Martinson.
