The Black Forest, known as the Taughannock by the Native Americans, covers the entirety of Mount Greylock and the surrounding mountains. The edge of the forest borders Ilvermorny School of Witchcraft and Wizardry.
The forest is considered haunted and is extremely dangerous, as it is host to a dark curse. As a result, students at the nearby Ilvermorny School are forbidden to enter it – even in the event of detention. Despite the legends that have grown up around the forest, a troop of Sasquatch are known to live in it.
The Magical Congress of the United States of America considers the forest a forbidden zone.
