The Great Shepherd Leader seemed to have long considered this question, and answered calmly, "According to the information we currently possess, there have been at least four waves of the Black Fog tide already. The first four waves all failed to occupy it, so why is it that only this wave can completely bring the Sea of Source to fall?"
Rod frowned, and just as he was about to refute, the Great Shepherd Leader continued, "In fact, according to some of my recent research, the degree of erosion suffered by the Sea of Source is far from as severe as we imagined. Over these past few days, in Trolian's Great Book Library, I have found a great deal of useful information. Combined with some ancient texts from before, I can infer that the extent to which the Sea of Source has been eroded is not even half."
Rod's heart trembled, and he hastily asked, "Really? How did you infer that?"
