Pure's secret weapon

In an open land where the floor was an iron red, structures that had been built were seemingly destroyed all over the place. Nothing left but rubble. However, a single one stood tall and strong out of them all. A tower larger than anything in the entire area. The tower itself had exactly a hundred floors and down below at the very bottom of the tower, the sound of fighting, and more could be heard.

Yet at the very top, on top of the tower itself looking down at everything around them, two men were sitting down.

"They sure like to fight, don't they?" Arthur said.

"Of course, it's in their nature you can't stop it, you should know that by now. I'm more interested in you though. Are you sure about your decision? You've spent enough time thinking about it, and I don't want you to regret your actions like you did before." The man by his side said.

Gripping his fist, the sword on Arthur's back started to vibrate.
