It is true. Indeed, that is why I dared not speak. I have yearned to be again at the side of my beloved Arianllyn, and my thoughts are with her now. But had I chosen to return, I would ever wonder whether my choice was made through wisdom or following the wishes of my own heart. I see this is as it must be, and the destiny laid upon me. I am content to die here.
