There's a place where never was always and everything is nowhere. Over, under, sideways, and down are all the same in this place of pastel colours. Every particle and mote of substance is lost in a wash of psychedelia, and any mortal's ability to comprehend it is minute at best.
This place is the home of the creator, Arceus.
And it is here that our story starts.
"… h-hello? W- is anyone there?"
"Yes, hello my child, welcome."
"Where am I?"
"This is the place between life and death, where souls pass through unto either their final resting place, or their next life"
"N-next life? I'm dead?"
"No my child, you are simply- yes, you're dead."
"Oh…"
…
"Well, as is customary, I'm here to congratulate you on attaining positive karma, and reward you."
"Positive karma? I don't remember much. Did I do something important?"
"Nope! Infact, you were fairly mediocre. However, due to the fact that your friendship with one Jim Thomas had changed his life for the better, you were a net positive on the world, and thus, shall be rewarded."
"Oh… well, that's good."
"Indeed. You will be sent to the world that your heart most desires to experience, with a body that your heart desires."
"Am I meant to do anything in particular?"
"No."
"Really?"
"Well, my child, what would be the point of sending you off with a reward if your reward was hardship?"
"Oh. I guess that m-makes sense…"
"Are you ready?"
"W- um, I guess..."
"Well then, Arthur Wimbleton, welcome to the world of Pokemon!"
…
"Okay, now where did I put that popcorn… ?"
