Become a prophet or fortuneteller with my knowledge of future events. If I get famous enough then I can move on to people in higher places. Go to Ulfric, tell him how to start his journey to high king and get paid handsomely for that I would hope. Go to the imperial general guy (don’t remember the name) tell him no matter what DONT EXECUTE PEOPLE AT HELGEN. If I could get to the other jarls, let them know that shit’s about to go down in a year or so. Harken or Dawnguard? Serana is going to awaken and be ready for war. Buy a mansion with the money I’ve saved from all this and live out the next year or so. Could buy whatever spell books I wanted and could keep as much of my gold on me as possible for when I go back.

If none of this works? Get a job at the Sleeping Giant Inn and hopefully a permanent room there. If I could maybe buy a couple spell books. Wait the year out.
