New Age

A global apocalypse decimates the population. The only survivors are young children. Despite insurmountable odds, the children grow and establish a community on the scorched Earth.
There is no technology, no religion and no books. It's a primitive, simple society - a bit like Rhyl on a bank holiday Monday.

Years pass and the community thrives, the initial children are now wise elders, or dead. However content they may be, there is always the burning questions: Who are we? Where did we come from? Who created us?

One day while out doing stereotypical apocalyptic dystopian stuff (probably gathering fruit and hunting or something) village teenager Katflap (although she's 15 she's actually referred to as 'five short of score' for some reason?) stumbles across some old ruins.
There she finds a strange object: sheets, like leaves, bound together and covered in script. It was a book.
The population of 'The outpost' finally has answers; they'd asked so many times, but who were they asking? And who had answered them? Who gave this gift?

It was God of course, a God they would study and worship. From that day forward their lives changed forever, they had become 'religious'.
It was two weeks later when Katflap noticed the first pair was missing, then a second and third. What was going on?

She approached the village elders and asked for guidance "What does our God say?" she said.
"Silence child" the shaman roared. "Do not blaspheme the Lord - address the overseer by his full title. His name as written on the front of the Good Book".
Katflap blushed and shuffled her feet, "Sorry, what does the...er...what does 'The Panty Thief of Bridgeport' say?" she mumbled.

The shaman nodded "Pray to the Great apostle Ed Wagemann from Amazon and ask for forgiveness"
"Thank you" said Katflap. The Dawn of a New Age had begun.
