Dragon-Blooded have been in Exalted since it was first created. So... I doubt that. I wouldn't know for sure, though. I don't know when Exalted came out and when Unearthed Arcana was released.

I'm pretty sure Unearthed came first, but Exalted seems to use the same bloodlines power thing. Interesting.
