The moment Angel entered the Mist Belt, he sensed an atmosphere utterly different from the outside world.
Mist was everywhere, shrouding this stretch of sea so tightly that not a crack showed.
The mist looked ordinary, but it was like a natural Mist Illusion. Not only did it obscure vision, it constantly misled intruders' sense of direction. Moreover, this sea seemed to possess an invisible magnetic field capable of affecting a compass's readings.
For that very reason, if ordinary people entered the Mist Belt, then unless they were exceptionally lucky, the mist alone could leave them forever lost in these waters.
And the Mist Belt contained more than just mist.
After entering the Mist Belt, Angel lowered his altitude due to his reduced visibility, flying almost flush with the sea. As a result, he could clearly see shadows passing beneath the surface from time to time.
Most of those shadows were enormous—giant sea beasts rarely seen elsewhere.
For instance, right now, Angel could see a patch of darkness beneath the Gondola. How enormous was it? Its end could not be seen with the naked eye. Even the massive cargo ship from Blue Tongue Shipping that Angel had encountered not long ago was probably smaller than it.
The enormous sea beast in the shallow waters abruptly surfaced.
"Twisting Ray." The instant Angel saw the sea beast's back above the water, he recognized its true identity.
The Twisting Ray possessed enormous butterfly-like wings like a ray, but its tail resembled that of a many-footed octopus, growing hundreds of slick tentacles.
This Twisting Ray, which had taken up three pages in Fantastic Beasts and Where to Find Them, and which the compiler had lamented was "an increasingly rare Demonic Beast, likely to go extinct before long," had appeared openly in the Mist Belt.
