Cormack and Conor:
“The twins were on either side of her, leaning in, each the mirror image of the other, eyes gray as the winter sky, hair deep brown and glossy as a ripe chestnut.”
From Daughter of the Forest
Conor (older):
“There were young folk wearing the homespun, both boys and girls; and there were men of middle years, of whom my Uncle Conor was one. Come late to the learning of the great mysteries, he was now their leader, a pale, grave man of middle height, his long chestnut hair streaked with gray, his eyes deep and serene.”
From Son of Shadows
