Clean game saves everywhere along the main quest. I saved 36 times as I played the game, in various significant places. I completely uninstalled Skyrim, and Nexus Mod manager, and deleted EVERYTHING that was related to them, including all files on my computer they put there. I then reinstalled Skyrim, and did the Main Quest only. I used a one-handed sword and Heavy Armor (Imperial). I also used the healing power, which raised my restoration. I did not loot anyone or anything (unless I had to for the quest), and tried as hard as I could to avoid starting any other quests.
Dragon Bones and Scales I collected are in the chest in front of Sky Haven Temple.
The Negotiations were:
Riften goes to Imperials, Markarth goes to Stormcloaks. Ulfric pays for Karthwasten.

The character is a nord, level 1. I did not level up, so you can go to the level up screen, and add Health/Stamina/Magicka as you please, and choose any perks you want. The only setting I changed was to put the game on Novice difficulty (It\'s hard when you can\'t level up). Everything else is the same. No mods or console commands used, and did not buy or sell anything.
And there you have it. Hope you enjoy.

You may do anything you want with the file, or use it in any mods, no need to ask my permission or credit me.
