The day where William and Chiffon would leave the tower had come.
Since the Floor of Asgard had no Guardian, William had given James that role. The Tower of Babylon had recognized the Half-Elf's decision and gave James administrative powers.
Right now, James had the same authority as the other Guardians of the Tower, and had absolute control within the 51st Floor.
William had also brought James inside his Thousand Beast Domain and introduced his Herd and Legion to his Grandpa.
James didn't expect that his grandson had a mobile army at his disposal, which made him look at William in a new light.
However, the surprise didn't end there. William had also revealed that he had formally taken the mantle of his father as the Dungeon Conqueror, which made James almost choke on his saliva.
