Essentially, what this is is what it says on the tin: A backwards story. Like the neverending story, but in reverse. So we start with the end, and go to the beginning!

Example:
Poster one: So she said, "Well that's too bad!"
Poster two: Then I said to her, "I thought you loved me!"
Poster three: That's when she took off her ring and threw it back at me.

And so on.
So let's start!

With the great techno-dragon Niddhogg defeated, the knight rode home on his horse, accompanied by the lovely princess.

The End.

With a swing of his mighty battle hammer and the crunching of bolts, our great hero at last defeated the foul beast.

"This is for all the innocent lives you have destroyed, monster!"

The valiant knight hoisted his weapon up, and shouted,

Panting, he got back up on his feet, the mighty beast still sprawled in front of him.

"I will not- must not- fall like this. Not here, not now! I will win this battle for all humanity!" declared our hero, struggling to his knees.

The princess, with tears in her eyes, shouted to her hero, "Please, get up! You have to succeed!"

The dragon, using what remained of its battery power, swiped the hero with the back of its massive claw sending him flying, and froze into standby mode, waiting for the sun to come out and recharge it.

Running low on energy, Niddhogg shouted, "You will die, foolish biological!"

The brave knight caught the lightning bolt on his magic shield. "See? Even your ultimate attack has no effect!", he said, laughing.

Knowing he cannot stop the mighty techno-dragon's lightning strike, our hero ran with haste to where his shield lay after it had been knocked away by his fierce opponent.

The mighty dragon charged up its dreadful lightning, which has fried many a hero before this one.

"Now, you are doomed," the dragon growled.

With an almighty roar, the dragon struck a terrible blow to the valiant knight with his fearsome tail, knocking his legs out from under him.

The hero turned away from the dragon and ran towards his shield, knowing that he had to pick it up to avoid sharing the same fate as the ones whose bones decorated the dragons lair.

The dragon slung the hero away from itself, causing the brave knight to lose his shield.

"You'll never hurt me as long as I bear this!" proclaimed our hero, holding his magic shield aloft.

The dragon laughed at the knight before saying "I should blast you to bits you pathetic human!"

Having finally made it to the dragons lair, the brave knight banged his hammer against the wall, shouting out a challenge to the beast. Within moments, the great dragon stood before him, angry at being awoken from its charging cycle. Upon seeing but a single man before him, the dragon snorted with cyborg derision.

Our brave hero burst out of the dreaded Forrest to see the dragons lair in which his quarry lay hidden.

With blow from his hammer, the great flaming wolf lay defeated, and the path was cleared.

The hero looks at his adversary rushing towards him, extreme heat emanating. He chuckled, and said to himself, "When all you have is a hammer...", after which he swung his weapon!

The wolf, angered that his prey remained on its feet even now, charged at our hero!

Hurt but not defeated, the hero stood back up, ready to deliver the finishing blow.

"This armour can withstand any temperature, beast. You lose." The knight taunted the wolf, even though he had been knocked down by the sheer force of the wolfs attack.
