Underwater tornadoes that struck the outer region of the Anairam Trench broke up the peaceful evening underwater. These apocalyptic, similarly-looking disasters are far more dangerous on land than they are underwater because, like land tornadoes, anything this tornado passed through would be sucked into its twirling body, which would eventually lead to one being destroyed within the tornado or thrown above.
Since the sea tornado was not only killing people inside its body but also drowning them, it was almost impossible for any group, not even the Fishmen or Mermaid Tribe, to escape. Therefore, they made every effort to save as many people as they could, since this territory was under their master's control and these human hunters had paid them for protection and direction, and they could not stand by and watch these men perish.
