Warhammer I Have Dark Age Technology

I, a time traveler, have a head full of dark technology. But I don't want to save humanity, nor do I want to be a savior. I just want to live my little life more comfortably in this broken universe. However, the Empire doesn't believe it, Chaos doesn't believe it, and even my Mechanicus don't believe it. They thought I was hiding world-destroying weapons. Well... They were half right. But are you sure you really want to see me take it out?
