From the way Neria speaks, it seems as though her world has a very organized way of looking at magic. And that interests Fortescue, as hers is the same way. Categories and terms shift, ever so often, but the way people view magic has been the same for hundreds of years. Longer, possibly.

This is helpful, actually. She can focus on the conversation and not so much the growing pressure she's putting off with her magic.
