Chiffon and William were currently on the 20th floor of the Tower of Babylon. In order to proceed to the next floor, they would need to catch some rare fish in the lake and present it to the examiner.
This trial could be accomplished individually or as a group. The overall score would be calculated on the number and rarity of fishes that were caught.
William and Chiffon took their fishing lines and stood at the fishing area assigned to them. They were not alone in their fishing spot because several middle-aged men were there as well. These men had been living in the Floor of Anglers for many years.
They were the people who had a passion for fishing and decided to stop the dangerous climb up the tower, and just spend their lives doing their hobby, which was fishing.
