"You're close." Harry admits, finally turning away from the image to lean back against the wall instead. He figures using the terrifying dragon as a reclining spot works well enough for a nose-thumbing too. "You've got your elements but there isn't so much a practical difference between 'light' and 'dark' magic. Actually dark magic would probably just be a different application of manipulating light, like using fire to suck heat from something...."

He trails off, realizing he's getting technical. Normally he'd be happy to sit down and talk shop, compare notes, but considering this girl just denied the existence of necromancy a minute ago... better keep it to the basics.

"Anyway, the point is wizards like me have a certain set of rules to follow. Break those rules, you're a warlock." He shrugs, looking towards her but just avoiding that direct eye contact to focus just above or below her eyes. Last thing this girl needs is a soulgaze on top of everything. "I've used necromancy but not on humans and since humans are what the Laws apply to."

He spreads his hands, waving them a little in the air.

"Still not a warlock."
