I was traveling across Cyrodill just for fun, out exploring. I saw a massive mountain, and decided to climb it. I was overly joyed when I reached the top (it took me about half an hour real time of tapping jump and running forwards, cause it was a sheer drop.), partially because I didn't hit an invisible wall at the top (I run into them all the time, it drives me crazy). Anyways, I was heading back down a different way (I was actually looking for the steepest way down and jumping to see if I could kill myself from a fall). I didn't die, but my health was very low after the first jump. Then, suddenly, battle music started playing. I got up on a rock, and looked around for a while. Nothing. I climbed down, sword drawn, then out of nowhere I was hit! I spin around, I see nothing, then I'm hit again, from right in front of me! I start slashing madly I hit something. It's invisible. I hit it over and over, and finally kill it, near death myself. I look around for a moment to find its invisible body. It is titled "Uderfrykte Matron". Quite an imposing name. I find a full set of fur armour, a unique bow, and a full set of Svenja's bones. I am very puzzled right now, but then I see something out of the corner of my eye, over a small ridge. I go to it, and I see another body. The body of "Agnar the Unwavering". He has nothing of interest on him. I eventually give up on trying to figure this odd occurrence out, and move on. However just as I round the next bend, I see a camp. I rush to it, and there is an incredible lookout, and the location is marked as dive rock. Oddly enough though, there are two bedrolls in the tent. I look around for a moment, then see a journal. I pick it up, and read it, and I learn of the story of Agnar and Svenja.
It was an awesome encounter/quest, probably my favourite. Does anybody know if this is an actual quest?
