George was curious, naturally. And after recent events, that was no surprise. The old man who stood before him seemed to know about George, how much, George didn't know, but was about to find out.
"We've been expecting you for some time now, George, we thought you'd have found the door before now, with that creative mind of yours."
"We?" Asked George. "Where's everyone else?"
"Oh, around, but don't worry about that, the important thing is that you're here now."
"And where exactly is here?" asked George.
The old man laughed "If I told you, you wouldn't believe me, and I know what else you're thinking; no, you're not dreaming, this is real. We're in a parallel universe, one which has been created from your mind."
George looked at the old man skeptically
"Is this some sort of joke?"
"No, no joke, I'm serious. Why do you think that wall appeared as soon as you said it? Oh, and hero? Don't flatter yourself."
George thought about this, then a thought formed
"OK...so, if I say 'And then our hero found himself in a large clearing, deep in a forest', then grass and trees and the such like will appear?"
But, the moment he said that, indeed, trees did grow all around him, and grass beneath his feet grew, then there was all the sounds of a forest, filling his ears.
George looked around in amazement, and then decided he rather liked this; he was, in effect, a god. And he liked the sound of that.
"So" George said to the old man "How do you know so much about me?"
The old man raised an eyebrow
"It's rather self-explanatory" he replied, but it was obvious George hadn't quite grasped the full idea here, "As we're formed from your imagination, then we've been with you since the day you first thought of us."
George looked at the old man, a memory coming back
"Oh, now I know who you are, you're the old guy I was going to use in one of my books, but didn't, for various reasons. But yet, you still exist....how?"
Sighing, the old man rolled his eyes.
"Because even though you didn't use me in the story, you still thought of me, imagined me, and the such like, therefore I have some sort of existence."
"Right" said George "But how does a parallel universe form from my imagination?"
"Ah, wondered when you were going to ask that" said the old man
"You might want to think up a chair, this could take a while"
Looking at the old man, George then said "So, our hero then found a couple of chairs, for him and his companion to sit on"
Sure enough, two chairs appeared, and George and the old man sat in one each
"And I told you, stop flattering yourself. Hero? HAHAHAHAHAHAHA!!!"
George looked at the old man, not sure what to say
"Um, anyway, are you going to tell me how this parallel universe formed?"
Stopping his laughter, the old man looked at George
"Ah, yes, ahem, well, it's rather complicated...."
The old man looked at George, a sly smile forming, and an odd glint in his eye.......
