You'll receive this trophy upon finding your first Beatrice stone. The first one available in the game is in Limbo. You'll find a tower after the sequence of fighting on Charon. When you reach the tower, you'll find a demon door and a hallway to the left. Down this hallway you'll see Charon's head (press R1 to free his head for the "Burning Eyes" trophy) and you'll also see an orange fountain with a Beatrice stone in it. Once you break the fountain, you'll receive your first stone, some souls, and the trophy.
