A strange key shaped like a wild beast's fang.
What manner of dilettante would create such a
key, and what might it unlock?
Go to the open area past the bonfire with Lion Clan Warriors and drop down the boarded-up hole in the ground. In Dark Souls II the Giant Basilisk is in this area, in Scholar of the First Sin it's empty. When you drop into the hole, beware of Basilisks.
