A Time Traveler's Mail

This is my story. Oh, you're wondering who I am? I am well known as the woman who saved your butt from extinction..... but just call me Quen for now. I would rather not say who nearly fried our entire race off the face of the earth. Because if I did, you would not be happy. I hope you enjoy this uh.... "entertaining" story of mine. So welcome to my nightmare, everyone. Keep your arms and legs in at all times, and "enjoy" the ride!
