From the introduction:
“Come on! They won't leave us alone for much longer!” Those words ring in your ears as you force yourself off the muddy, cratered ground. You get the sense right away that this is a war zone, but something about the air tastes cleaner than you're used to, even in this mess. As your vision returns, you take the hand of the stranger standing over you, fumbling away from the scene.
It takes a few minutes before you've fully regained your footing, and you can barely think through the massive headache, but at least you can see who you're looking at now. Of course, that just brings more questions – such as who they are, where you are, and why this person seems to know you. You can probably tell a few things from your initial conversation, though.
