“ In decades past, the three clans of the island - tree witches, gargoyles, and wolves, had cloaked their land with many layers of protection. Their combined magic had created such a powerful force it had remained undetected by human technology. When a feud erupted between the witches and gargoyles twenty-five years ago it led to a division of land. Without reinforcements from the clans' combined magic, the protection seeped away. ”
