Description from the BGW website:
Legend tells of the old Witch of the Woods, who descended upon the ancient village and wreaked havoc. Nobody alive has seen her, but if you’re brave enough to travel the woods at night, it’s said that you can hear her chanting and crying out to the skies. Those who give in to her control become her disciples, and those who don’t…inevitably meet the same fate. But this is only a story, right?
