A place with an unknown origin. Arthur went there alone because of how dangerous the place was.
The thought of getting anyone he cared about near danger was something he did not want.
Arthur pondered if he should bring Kai along, as he was his disciple, yet it was too dangerous. Kai was not strong enough to adventure inside that place.
"When I return, I should teach him more stuff. I'm such a terrible teacher." Arthur thought as he gazed down at the hole they had used before.
Obviously, a rope was not needed for someone like Arthur, as he flew down like a celestial being.
The darkness also did not affect him either, and everything was as clear as the day for him. At first, there was nothing around him, just the walls and a few small animals, but as Arthur traveled deeper, the magical beasts showed up.
A type of green scorpion that was as big as a carriage. It had a tail with a stinger, and just the stinger was larger than an average human.
