From the back of the book:
The history of Cadwallon is a succession of dire events leading to the departure or the disappearance of the inhabitants of the peninsula of Lanever, surrendering the ruins to the magical groves and to the fayrees living there. This region has staged so many battles and shed so much blood that the elder races believe it is cursed.
