"It doesn't matter," Corvin said, turning to look at me. I made a face. "No seriously," he continued, "make that face all you want, but there's no reason why you can't use Edaya's theories of magic over Groyett's. They both cover particle streaming." "Ok, but they don't deal with wave forms in the same way," I replied, tapping the copy of Physical Magic Methodologies on the desk in front of me, "Groyett covers the energy fields portion way better. It's like you don't even want to acknowledge new research." Corvin made his own face at that. "Does it matter when you get the same result with your output anyway?" he said, lifting his shoulders in a half-shrug. It's an argument we've had many times before. Each time we learn new spell sequences we have to test power output against each other, and each time we match each other evenly.
