I just want to say thanks to everyone who has helped me with this one.
Ones I particularly liked:
Auronomy was VERY cool sounding. However, I'm worried about having two 'A' words for the magic. (Still debating this one.)
Ferramy also had me for a time. The only problem is that I really want something that has the same 'feel' as the other two magic systems. This doesn't quite resonate right.
Sangrimancy is also very cool sounding. The only problem is that I don't really need another 'blood' related magic system. Skar--I stored this one away for potential use in another world.
However, I think Jade has really had the best suggestion on the thread. Dropping the second 'R' from the Ferr prefix makes it work a lot better with things. And, to avoid the 'feral' reference Stacer noticed, I think using the original Latin 'u' with the 'Fer' gets us a better word.
So, the current winner:
Feruchemy. It isn't actually the coolest sounding word on the thread--I think that's a tie between Auronomy and Sangrimancy. However, Feruchemy 'Fits' better with Allomancy and Hemalurgy. The three have a kind of internal resonance, and give the right feel.
Thanks all!
Now, another task. These three are all active arts--something done, rather than simply a study. I'd like, however, a good name for the blanket term for the study of all three magic systems. A name for the system of the world, rather than the specific magical applications of this system.
All three systems use metal in different ways, and all three draw power for the user from different places. Any clever ideas? (Initial thoughts for me include using 'ology.' However, I'm not opposed to something longer, like I used in DRAGONSTEEL. (Realmatic Theory, for those of you who haven't read it.))
