Because the Author Was Too Lazy and Didn't Want to Update the World of Destruction, but Was Stopped by a Fish.

It tells the story of a fish-man named Harpy who is under the influence of the protagonist's aura. The fish-man is a vassal or creation of some powerful deep-sea creature that is still sleeping or waiting. Historians have made various speculations and doubts about their motives, believing that it was their migration that oppressed the living space of the fish people, which led to the fish people starting to invade the land. Other historians believe that the murlocs may have been slaves to these sinister amphibious creatures. The appearance of the fish-men and their invasion of land represents the awakening of this powerful creature. Some evidence shows that the fishmen, or their ancestors, may even be older than the trolls. This novel and its characters are purely fictitious.
