You follow the path around the main part of the ruins to the northeastern part of the island, where a ruined guardtower is located. Climbing the ruined stone steps to the top, you can see the whole island, the ruined fortress, and three more guardtowers in the distance
You also notice a chest near you. Writing is carved into the wooden top: "Can't open, help" and there is a rusty paddlock, which promptly breaks off when you examine it. When you open the chest, it is full of old Vitality Potions.
