Yeah... Minerva totally stole the idea from me!

Erm... moving on.

The concept or rather the different parts of the concept existed before Mashima or any of us were even born and I had similar ideas about this even before I started to read Fairy Tail (the inspiration coming partly from the "Passing of the Technomages" Trilogy of Babylon 5 books and partly from Baldur's Gate).

So no, it's definately not FROM Minerva, even though it partially intersects with her magic.
