S.k. Michels said this quote

“ What did it matter that the Light had been taken away from him? What did it matter that Arienne was gone? If it took a thousand years to find her...if he had to cross boiling seas or raging skies...if it cost him his eyes or his tongue, his hands or his feet, his very soul... He would relinquish it all, if it meant he could keep that promise he'd made so long ago. He had nothing else. Without this, he knew, he would simply wither away. ”
