Castor explained that the Golden Bough Legion was examining the secret of the Eracus Temple Cavern. He asked you to meet with Axelion and receive a task. Following Axelion's instructions, you collected the Tower Wall Fragments in the temple and brought them to him. Axelion rebuilt the wall and told you that there was something written on the wall. He read out that the Temple Cavern used to be a playground for a child named Kahrun. Castor was amazed about the news that the Eracus Temple Cavern was not actually a temple, but a playground.
