The fourth episode is here! Mason and Reginum have finally reached Bish, and found their sister. When they reached her and told her of their father's letter, she showed them another piece of paper with their father's handwriting on it. The only word on it, Talket, was referring to the old city to the east. The three sibling know they must get to the aged city to find out more about their father.

On their way, they run into Mount Volgravia. The roads around it have been blocked by large boulders, and the mountain is too steep to climb over. So, they must go through the volcanic hill to reach their destination.
