Rest and watch the cutscene, Hircine will tell you of a Rebellion at Castle Karstaag that he wants you to stop because someone he likes is the leader there. You will be in Werewolf form which will make traveling to Castle Karstaag much easier than walking there if you are on Solstheim, otherwise you will probably want to wait until you are a human, though you will lose a large amount of health (unless you kill a person nearby). Castle Karstaag is most easily found by heading North of Skaal Village and following the coast west.
