Adventures in Skyrim - spoilers ahead! In this entry I am following my custom scenario "A Curse of Iron". You can follow the rest of the story here!
Asked around at the Winking Skeever for clues, getting an extra one from the kid Minnete who happened to be there too then began going door to door looking for the agent in this city, but finding none. Visited Proudspire Manor to let Njada and Jordis know I was ok (tested them and they weren't agents either) then went next door to the Bard's college where everyone seemed to check out until I got to the kitchen. It was the old cook! I simply waited for an opportune time and slit the old man's throat as he ate. With that easily accomplished I noticed more Pentius Occultus agents lurking about so with Kharjo we set to work eliminating all of them, where I managed to finishing stab one and throat slit another. A pair of guards got involved and they needed to die too, fortunately I managed to snarf a hunting bow from one of them. We then quickly shadowed our way back down the side entrance and began to hoof it to Morthal.
I knew this would be a harder task since I couldn't swim "up" waterfalls meaning I'd need to be on the road this time, and sure enough Dragonbridge proved a very tough place to pass with it's high volume of guardsmen (bad luck as a patrol was there too). Told Kharjo to just buy me time then escape so we split up, with the cat holding off a large portion of the guards while I high tailed it outta there. After what seemed to be a really long sprint across the mountains I was clear, and back on the road where I encountered a friendlier group of three Stormcloak soldiers who happened to be walking in the same direction I wanted to go. Figured it was safer to travel together so I just strolled with them down the road, and after a few minutes a familiar khajiit came running up - it was Kharjo! He somehow gave the Dragonbridge guards the slip and got ahead of us.
We were in high spirits as we neared Morthal when a group of forsworn raiders attacked. There were only three of them, but each of them managed to kill a guardsman before either myself or Kharjo could finish them off. I was so angry that I (finishing move) beheaded the last one. Finally we made it to the City of Stone and easilly found the last agent inside the Silverblood Inn itself. It was Muiri, who apparently would do anything for money. Despite the inn being crowded at the time I already knew how to take her out - hidden from a room with an arrow to the neck. Why would she turn on someone who helped her!? No matter, at least I'm closer to getting this curse removed.
