I had far too much Tolkein and Glen Cook in my life that I absolutely adore to think magic has to be rigidly defined. I agree on the judgement of stuffing with the caveat that it happens at high velocity.

Thanks for catching the implied high velocity! Agreed re Tolkien & Glen Cook, plus Le Guin, McKillip's Riddlemaster of Hed, etc. Rather tiresome when magic is neat & tidy: that's so not the point! Ineffable & wild magic, please
