World's Essence

The turn of events took Arthur by surprise. He never expected the strange turtle down there to be one of the four legendary creatures! Not that he knew much about those beings, but Ikarus was one of them, and Arthur knew him.

"If I can somehow break the barrier, would you reward me with something?" Arthur asked.

"Well, I don't believe you can unless you have the moon essence, but that's impossible. So, hypothetically, if you break the barrier, I can grant you the world essence."

"You swear? No going back on your words?"

"Are you doubting me? Brat, I can give you the world essence right now, as it will not matter if you can't leave this place."

The turtle did not like someone doubting its word, so it decided to give Arthur the world essence before they even tried to escape!

It did not matter, as even with the world essence, Arthur would not be able to leave, and if Arthur broke the barrier, then the turtle was automatically free too.
