I guess at some point i found a flame thrall book... but its weird because my conjuration is only at 37... I guess when i found the book i didnt think anything of it

It is a master level spell you get as a reward from completing a quest from the guy who teaches conjuration at the College of Whiterun. It is a Skyrim spell and not a new one.

But I remember finding one also. So cool.

It has a chance of spawning in Apocrypha. The only master level spell that can appear I think.

I know that... but its new in the fact that its the only master level spell you can just... find

I know. I saw that and said, what?? My conjuration was at 86, but I loved the idea that I had it already.
