I'm not worried it may be too much. That's not my concern here. You're bringing science into magic. Now, could you maybe eat ice and gain ice power that way? Sure, fine. Natsu eats all sorts of weird things. The dummy. But Water Dragon magic is Water Dragon magic. I'm sure there's an Ice Dragon out there, somewhere.

Blugh, I have to go to work. I'll probably be back on when I get to work.
