Unfortunately I'm a little further south of you, but I just thought of somewhere north that people would know of and Scotland came to mind. And I'm sure you've got lovely scenery. (Minus the dragons, hopefully.)

plunder old ruines

As myself or as Dovahkiin?

As myself I would get myself to the nearest walled city, STAY THERE and get a job. Maybe open up a bookstore once I'd earned some money. Or look into becoming an apothecary. Potions seem fun!

As Dragonborn, I would get myself at least one very strong bodyguard, train like a maniac to prepare for killing Alduin. If I survive that (which I most likely wouldn't), I would work out a plan with Paarthy how to train ordinary humans to shout. Maybe get Ulfric in on that plan as well, depends on which side I would like best in the war. Oh, and I would really try to negotiate a lasting peace treaty. Have no idea how, but I'd try.

I would probably be fertilizing the landscape as saber cat poop.
