Sunken Journal from Yenay, a Mystery of the Shrine of Ocean's Fortune.
My dearest love, the plan I spoke of may take some time, so I need you to be patient. I will find the heart of the Sunken Kingdom and beseech the Sea Queen to return you to me. Having learned her story, I know she will understand my pain. Perhaps she is the only one who truly can. By returning us, love will triumph over hate and I can't help but feel that is the ending she wanted for her own story.
