Who are you?

"I am D. H. W., or simply Hades. I have created this place and I rule it alone."

"What do you mean 'Created'?" — Beth fired right away. — "Eh, wait a second."

"You're truly hungry to grasp all the knowledge, aren't you? I will tell you everything, but only if you agree to share my creational powers."

Beth was clearly out of her league. This man knew too much more about his own proposition so far.

"You must have taken my memory. I can't make supposedly life-altering decisions if I don't even know who I am?"

Hades smiled through his deep moustache. The power of having much desired knowledge would spoil anyone.

"Here is the deal. Option one: I reunite you with your memories and you go home, and your trip to my domain becomes just a weird dream. Option two: I let you inside all the secrets of the White Mall, and you become my right hand, but you shall not remember who you were before."

"You said 'powers'? What exactly are your powers?"

"Like I said. Creation." — A door formed itself on the nearest wall. Darkness lied behind, but Hades stepped in and invited Beth with a subtle hand gesture.

As soon as she went through, the gravity was gone. The Mall was gone, too. She dropped her jaw as she saw stars and galaxies slowly getting visible all around her.

"Breathable air and tolerable temperature were the first things to be brought in. Then, the stars were too bright, so I added some slight toning to my bubble. That bubble grew vastly since, but outside of it, yes, lies open space. I can tell you some more right now, but I think I made my point."

"Yeah, I got it. You are a god and I'm the chosen one. I'm ready to speak too."
