Isso soa um pouco como Birthgrave de Tanith Lee. A Wikipedia tem um resumo do livro aqui .
O protagonista, Karrakaz, acorda sozinho e com amnésia:
To wake, and not to know where, or who you are, not even to know what you are—whether a thing with legs and arms, or a beast, or a brain in the hull of a great fish—that is a strange awakening. But after a while, uncurling in the darkness, I began to discover myself, and I was a woman.
A mulher cega seria Kotta:
"Ettook must have the mask,” Kotta said. “It is his right. Later he will have a right to your body, when you are delivered of the child.”
“I must not show my face,” I whispered.
She gave a fox’s bark of laughter.
“Oh, so you learn the tribal ways so soon. That is good. Well, no fear that Kotta will see your face. Kotta is blind.”
Karrakaz tem um triângulo verde brilhante feito de jade em sua testa.
