In the witch kingdom Hyalin, the strength of your magic is determined by the length of your hair. Those that are strong enough are conscripted by the Witch Guard, who enforce the law in peacetime and protect the land during war. However, those with hair judged too long are pronounced enemies of the kingdom, and annihilated. This is called a witch burning.
The young witch Nyneve, who is haunted by the death of her father and the threat the Witch Guard poses to her own life. When conscription rolls around, Nyneve has a choice to make; join the institution complicit in her father’s death, or stand up for her ideals?
