The Agrian and Shaloor are two kingdoms that have held a bitter grudge against each other for centuries. Even small disputes have led to bloody wars. So you can only imagine what happens when Erland, a young Shaloor, is found beached in Agria.
He manages to escape by pure luck, leaving him with the meager task of returning home. Simple enough. Unless, of course, Erland wishes to do so without drawing the ire of the Agrians or their god. That might take a little more effort.
