Days of Future Past - Part 1: Past Tense

Paul's been having a bad day, perhaps one of the worst days he's ever had. And now into the middle of all this, his instructor just got drafted by some mystical goddess to help save a world. As for Paul? Well, he's really not supposed to be there, and if he thought he was having a bad day before all of this, it just got worse, a lot worse. He's now on a one way trip, forced to help a man who despises him while at the mercy of the world's biggest trickster.
