Prince sure is sitting quietly in his boat.
(He's double-checking his immortality again, and trying to construct a plan to retake his empire. It is going to be a bit troublesome. He'd have to get close enough to touch Nirue in order to know exactly what her protections are, and without knowing that he can't know for sure that any given method of killing her will work on the first try; and he is as certain as he can be that his immortality will hold against anything she could possibly do to him, but that's not entirely certain enough... also, even if she can't harm him, she can harm lots of other people and certainly will if he provokes her and then allows her the opportunity.)
