Once upon a time, there was a player.
The player was you.
Sometimes it thought itself human, on the thin crust of a spinning globe of molten rock. The ball of molten rock circled a ball of blazing gas that was three hundred and thirty thousand times more massive than it. They were so far apart that light took eight minutes to cross the gap. The light was information from a star, and it could burn your skin from a hundred and fifty million kilometres away.
Sometimes the player dreamed it was a miner, on the surface of a world that was flat, and infinite. The sun was a square of white. The days were short; there was much to do; and death was a temporary inconvenience.
Sometimes the player dreamed it was lost in a story.
Sometimes the player dreamed it was other things, in other places. Sometimes these dreams were disturbing. Sometimes very beautiful indeed. Sometimes the player woke from one dream into another, then woke from that into a third.
