The Knight Of Tehreas explains to us that this place was inside the Grimoire of Ruination. This place was called the Ruin World, an exact place like Acres but wasn't Acres. We're kind of confused when he said that but Vicar asks the question for that.
"So this world is Acres or not?" Vicar asks the man with the full armour.
"It's Acres just the opposite of it, just like the world have good and evil... this world represent the evil version of Acres." The man said.
"If you said was true, then the desert was the Misty Desert?" Vicar said that.
"You're right, it was the counterpart of Misty Desert but in this world, it called as the Treacherous Desert." That man said.
Before the man could continue on his explanation, Vicar then asks him a question. "Okay but before you explain any further, would you mind telling us your name?"
