Kind of a Joke story. I just think about how screwed the world would have been if some old man turned out to be the Dragonborn...
Dragonborn Origins: Age
You whippersnappers want to know my story? Okay!
My name is Barnaby, or Barnes for short. I'm 83 years old, long since retired from working at the mill. I live in the drab town of Morthal, a swampy place in the smack dab middle of Skyrim. Pretty much a horrid place.
Anyways, so one day I was making my way down to chat with the Jarl when that big lizard came flying out of nowhere. I, of course, was pretty amazed at the big thing. Though I've been kind of creaky recently, I immediately drew my war axe. Waving it above my head with both hands, I ran straight for the beast.
However, before I could get close, that big lug, Bulldo, was already bashing at the dragon's skull. I ran up just as he dug his knife into the dragon's skull. That show offish youngin was always beating bad beasties! Where's my turn?
As I got close, my legs crumpled from the exertion. I fell down, but watched as the dragon decayed in a big pile, burning up its own flesh. Bulldo didn't get away in time, and got burnt to a crisp. Good riddance, I say!
Suddenly, big white streams of energy shot out of the dragon, turning this way and that, like it was looking for something. I pulled myself to my feet and stared at the things. Suddenly, they flew straight at me. Before I could do anything, they shot right into my chest, rumbling around my body.
I fell down again, and struggled against the weird twitchy feeling in my arms and legs. I writhed on the ground for awhile, but then I was able to get up. I felt a lot better than I'd felt in a long time. I looked at my arms and found that they seemed thicker than normal, a lot stronger. The same with my legs. I didn't hurt all over anymore; and I could really breath for once! I realized that in the weird magic mumbo jumbo, I'd been given my health back. I was still my old sod of a self, but I could do things again!
I skipped up the road, enjoying being healthy, but then this big cough started rising through me. I let loose with a loud couple of coughs, then yelled a weird word I thought of.
"FUS!" I yelled.
Right as I did it, a Shout returned from the mountain to the south east.
"DOH VAH KIIN!"
Right then I remembered the legends of old, back from before the founding of the empire. I was a Dragonborn! I yelled in happiness, a grin spreading across my face. The Nine Divines had given me my health to serve as the Dragonborn of this era!
AND THE REST IS HISTORY...
