"I have books like that, yes, but at a relatively elementary level... I don't know nearly enough to guess if it would be possible to make new fairy kinds by magic with our native sorts of magical properties intact. I imagine the effects on geographical areas, such as this forest not having a night or the Forever Snows always snowing could be accomplished by spell but I am satisfied enough with the forest's layout to have chosen other priorities than remodeling it. I haven't the first idea about how speaking could have been done by spell - it would have had to be done by somebody, and if they couldn't speak I'm not sure how they'd conceptualize the magic - but that doesn't seem like a fundamental limitation of the system, per se."
