No one knows about it anymore, but a little while ago, the world ended. The 6 final humans all shared a glass of alcohol together as they prepared for their species to end.
And then it didn't, thanks mostly to me.
But to save the world when it was past saving, to rewind time how I did, a few horrible things needed to be done. I needed to ensure that I was the very last human alive, the hard way. And though I didn't know it at first, I needed to take other people back with me. So, I return to the world five years before Armageddon, unsure who has hitched a ride backwards, and if it's those who remember what I did to get us here.
