1940: Kylie Morgan, "The Saxophone Dancer," speeds Mellowdy up and rockets it to international fame. The new, faster, style gets nicknamed "smoke music," a reference both to the fact that the new music is "hotter," and that dances are often held in smoky, grungy locations where upstanding citizens don't venture. This is a further insult to citizens in equatorial Snickerry, who have religious feelings about food quality. Citizens of Zenxon are bothered not so much by this, as by the fact that the dance is picked up by the fleet-footed sprites, humans who had been permanently changed by wind magic. Though sprites and humans get along in Snickerry, racial relations remain rocky in Zenxon. It looks something like this:
