Blessed by the divine, Eden is an idyllic island protected from outside harm by its guardian, the silver dragon. One fateful day, the dragon finds a small girl on the island's shores. Teaching her love and compassion over hatred, he raises her as his own. But their time together can't remain peaceful forever—Eden, rich in resources, is a prime target for humanity's advancing military might. In the face of violence and hostility, will the girl heed the dragon's words? And can they defend their coveted paradise?
