Introduction
Your alarm goes off, its Monday morning.
(Select gender and name.)
Your name is [name]. You're a young [gender] who works at the local carpet factory. You never paid much attention in school, but it doesn't really matter when it comes to getting the bills paid. It seems to be a normal Monday, and its time for work.
The protagonist navigates though the house, and will eventually find his way out the front door.
You went out last night, and as you roll out of bed, your head aches a little. You grab a glass of water and swing by a doughnut shop for breakfast. You then arrive at the carpet factory.
***
An armored car pulls up, seeing you alone behind the factory.
"Hey you! Come here! Get in!"
Get in the car.
"There's not much time explain, but we're sending an emergency launch of a passenger shuttle to Calydon. Will you come? You realize that you must drop everything. You must leave everything and everyone you know behind."
