Now to me this looks like dracomancy, but this is the only article in TES which i have read which has the slightest bit of dracomancy, i asked some people who say that the article is inaccurate and that dracomancy isn't possible in the TES world, because of the significance and sacred value to the empire. Other people i asked said that Tosh Raka is actually a dragon, there is after all the theory that dragon's can shape-shift so he could have been a dragon from the beginning.
I'm thinking that if TES V is set in Summerset then we may see a bit more of this topic, after all that is sort of the mages capital of Tamriel, and they are trying to achieve a complete monopoly on the magic business.
What do you guys think?
