I've read about sea dragons in a fanfic, but I don't know if it's canon, besides the problem of how he would get a sea dragon or an egg. Only in Valyria would he have this chance, but then comes another problem, how to know that it is a sea dragon egg and that he has an affinity with it, to get to one last problem, how to hatch it? I'd rather he get a form of magic that links him to the dragons in his family vault or be left with no dragons at all.
