What year I was frozen

I just finally remembered what year it was when I was frozen. It was 17185 CoL. Pretty sure it was close to that. We got word that there was some type of rebellion to the east, and we were to prepare in case we were invaded. We were invaded, by some Orcs and humans that developed strange magical powers that made them more bloodthirsty. We fought them as best we could, but during the battle I was magically frozen when some type of magical eruption took place. The next thing I knew for sure I was being rescued by the Death Knights.
