a prophetic revelation, especially concerning a cataclysm in which the forces of good permanently triumph over the forces of evil.
As Crossbow Inc. grew from a struggling startup to the biggest (known) incorporation in existence, you sat, controlling your company (and eventually the world) from your spinning office chair, in your skyscraping office building. You thought the buildup was hard, but the breakdown will be the real challenge. Crossbow produced most of the world's goods and practiced most of the world's services. You never thought it would end. But the "Rapture", the one that many of your former-employees believed in, has come. You thought you were a good person, maybe a bit greedy, but you thought you would make it. You were the richest person in the world. Maybe that's why, but there's no time for deep questions now. You have to prove yourself worthy.
If you die before you have proven yourself, then that might as well by the end. But if you can survive long enough to show whoever's up there that you're good enough, maybe he/she'll take you. But you're not alone. Humans, or what they've become, roam this world, hungry, dying, waiting. You've read about what happens after the "Rapture" (you were forced, of course). It doesn't sound good.
Now get going, you can't read your way to safety.
