Prologue
The lights dimmed, and all was dark for a few seconds, before a bright spotlight lit upon a fairly nondescript man, who looked exactly how you wanted him to look. A large, two-panel slot machine stood beside him, lit up with many flashing lights and sparkles. The diverse beings that made up the crowd cheered wildly, screaming theirs heads off in excitement, stamping their feet and clapping their hands in a rhythmic manner. They quieted quickly as he held up his hands in a placating fashion, grinning widely, before he began to speak.
"Ladies,gentlemen and everyone else! Welcome to the first episode of our brand new show, Life Swap; the game where you literally swap lives! There are only two rules! First, start at the beginning, and finish at the end, and second, follow the basic plot! I am your game host, The Eternal!" He flung his arms out in a dramatic fashion, lapping up the applause and cheers of the audience.
He stood there for a few minutes, basking in the attention, before a stagehand coughed, bringing him back to the task at hand. The Eternal shot an annoyed look at the stage hand before drawing the crowd's attention to him again.
"And now, the moment you've all been waiting for…" He grinned and gestured to the slot machine beside him, "the contestants! Now remember, these are completely random, so not to worry! Here we go!"
He pulled the lever on the side down, and the machine started with a clink, before the slots began spinning, beeping as the names went past in a blur. The machine started to slow down after thirty seconds, and with a final beep, beep…beep…clunk it stopped on two names.
"And the first contestants are…Alec *****, from 'Planet Earth', and Revan from 'Star Wars: Knights of the Old Republic'! And now…Life Swap!"
