The demon Docar needs to take on a physical form to leave his mountain and rule over the lands of Nartanis, and he is prepared to use any tool at his disposal, from fear and hate, to love, courage and hope. But there is opposition from the three races that inhabit Nartanis: the wolves, intelligent, capable and observant, fearful warriors and skilled trackers. The túlidos, who venerate beauty above all else, are skilful and secretive, with prehensile tails. And the teráis, of human appearance but with the peculiarity that some females give birth to fearsome neyíns, giants who grow to over three metres tall, and are genderless, violent and devoted to their king.
