I am currently level 28, but on my first character, I was level 14 or so (my save got corrupt.)

I found some Khajiit caravans that had 4 bottles of Skooma. Best day of my life. Have you found any yet?

I did.

Hm?

I was in Whiterun, and I see TWO DRAGONS and they stayed in the sky, as I waited to fight them. They then flew away after 5 minutes.
