Visiting D-23 Real Quick

In front of an intimidating wall of red fog stood two Climbers and a bumpkin. 

"Wow! This is so damn impressive! It really covers the whole city?! I understand why you like this place now! If you build a cool castle in the red fog, it will totally look like a mystical land! Then you could even start a tourism industry. Actually, why haven't they done that?" The candid agent was having a blast. 

That is when an old guy approached. He seemed to have endured too much of life already. He had seen their car align near the fog and how young they all seemed. He had left the comfort of a portable camping heater to come warn them. 

"Youngsters, be careful. This place is not one where the living should be. This beautiful red fog is a land of death…." The saleswoman began trembling as she unconsciously took a step backward in fright. "…Or so that's what they used to call it. Nowadays, it's a huge waste of time."
