Find the nearest brothel, get some mead, and chill out...
Just Kidding!
I'd probably chill with Marcurio and have him teach me some destruction magic. I'd use it in conjunction with swords. I'd also chill with a puppy!
With the power or swords, flames, a sassy Imperial, and a puppy...what shall I do?!
Kill every damned Thalmor and dickish "SAV SAKRAM CAZ ITS KOOL!" Nords! Plus, Ulfric...fuck him!
Well assuming I wouldn't die, which realistically I would as soon as I arrived, I'd either settle down as a farm worker in a smaller town, or somehow make it to the college where I wouldn't study magic, as I feel that only the elite could probably get into such a place, and work as a janitor/library assistant. I'd not learn much there but pick up very basic alchemy knowledge which would help me make money from time to time.
I'd become a traveler, exploring the extremities of Skyrim to unlock the secrets of the land. I'd probably become a member of the College of Winterhold, and would most likely build a shrine to Hermaeus Mora on the shore of the Ghost Sea north of Winterhold. I enjoy the study of almost any topic, and would probably start some sort of fine arts college in Winterhold if I ever managed to scrounge enough money together.
I would live in a small house in falkreath hold, with my garden, and make potions to sell and make some coin (imagines lakeview manor). Would become a vampire because I enjoy keeping to myself. In my spare time I'll learn magic of all kinds (even beyond the spells in the game). Maybe join the college
I thought about not knowing magic, but since everyone in Skyrim seems to have an equal aptitude for learning spells, I think I'd be fine. All you have to do is read the book, right? :)
As far as being serious about what I'd do, I'd probably become a servant of Stendarr, use a lot of restoration magic, and use a sword. Possible supplemented by a shield and bow, since I shoot bows in real life. I'd complete the main quest and side with the Dawnguard, trying to be a holy warrior.
Hmmm. Difficult to say. I like playing two sides, one character all good and one all bad. So which would be my true self since I'm a bit of both. Probably sign up to the Thieves guild to get in good with them. Best thing to do first is make money. Become friends with Karliah and become a Nightingale. Marry Brynjolf. Build us a house and live care free while stealing other people's goods. I would stay away from choosing any sides on the war or The Dark Brotherhood. Steal, slay dragons and stay human
Join the Dark Brotherhood. Murdering people for money sounds like fun. LOL
In all seriousness, I'd probably specialize in Light Armor, Two-Handed, and Smithing. Be a pure warrior type thing. It would be physically demanding, but I think I could handle it.
I don't know who I'd marry. Its hard to say for sure what they're personalities are except J'zargo, and I am neither attracted to men nor beast folk. I might consider Serana.
I'd complete the Main Quest, Dawnguard and Dragonborn. I would never do a Daedric Quest, regardless of the Prince. To be a servant of deity for eternity after death? No thanks. Sovngarde is much more preferable. I would complete the Companions Questline as well, then cure my condition. Like I said, no Daedric Prince shall possess my soul.
A scholar, maybe a scribe, I'm never good in actual combat, so I might use magic, maybe Conjuration to summon a Frost Atronach to protect me or Alteration, so I won't die that fast, and of course I'll be using the scrolls I wrote, but nothing that involves raising the dead, respect them and they will respect you back. I might be a bard, I suck at singing but then again...the way the flute is played in the game is very much like how I play the recorder, so maybe, and enchanting sound interesting so maybe I'll try it if I was in Tamriel.
I would be a revolutionary orcish bard who would invent lute distortion and thus Heavy metal !!!! MUHAHAHAHHAHAHAHAHAH!!!!!!
Actually, I would be a Breton Arcane mage, studying at the College of Winterhold, slashing people apart with a blade so sharp it requires no strength, and living in a secret cave underneath the temple of dibella in Markarth. Fcking Yes.
