I think mine is from Scion 2e. I had talked to the GM, and planted the idea that my character's next title (you get a title every time you gain another lvl of legend) would be "Lady of the Wild Hunt", as in she had participated in a hunt. He thought a much better idea was that she would become their leader...
So, the characters were in Ireland. We had just finished another adventure,and was having fun at a pub near the hotel we stayed at. I heard hunting horns, and wolves. So I went out to investigate (of course without telling the others). I then met a bunch of wolves that was around 1.5 meters tall, and the leader (probably Herne), who said it was my time. I joined, and become a 3 meters tall wolf.. (measuring from the ground up to the shoulders when it stood on all 4 legs).. There we hunted down an ogre that was the leader of a criminal organization He was tough, but he became my chew-toy (that she channeled the full power of the Wild Hunt, while she fought him, probably didn't help). The hunt also took out the rest of his family, who were evil ogres, as well as his whole organisation. So crime in that part of Ireland will be much lower for some time...
My friends, who couldn't track me down, decided to leave the hotel and go back to America. (all but one of them). My character then showed up at the hotel 2 days later, all bloody, together with a guy she had picked up somewhere on the way back. Both were rather out of it, and had basically only sex on their minds. 2 days later, she wakes up wondering where she is, realizes that she is in her hotel room, and that she is not alone. everything is covered in blood. Her first though is "what the hell happened?". She sees that she is not hurt, the guy isn't hurt either, but he is whimpering that he can't participate in any more sex (she had much better stamina than he had). He has also a lot of bitemarks on him after 2 days of the wildest sex either one of them had had, and the guy will probably have some mental trauma. So my character goes up and showers, and then goes down to eat breakfast. All the old people at the hotel just look at her, in terrified silence, and slowly backed away as to not attract her attention...
The wild hunt was a primal thing, part fae, and the emotions that filled participants were a lust to hunt, and devour their prey, and extreme horny-ness... My character got hit hard by those emotions, and it took some time before she could get it out of her system. In the meantime she had basically considered everyone as prey, with almost 50-50 chance of her killing anyone she met and drinking their blood, or having wild sex with them..
She will not be hit that hard next time.

I will also put experience-points into getting so I can summon parts of the Wild Hunt. As an aftermath, large wolves have been spotted near where she lives. Part of the hunt keep track of her (she doesn't know that yet).
I am currently writing a short-story about that aftermath, from the viewpoint of a poor police-officer that has to investigate the dead criminals. He realizes that things are out of his jurisdiction, to put it mildly. The Wild Hunt follows its own rules, and does not care for mortal laws.
