It would augment this story to illustrate it, so you can see all the different kinds of people, and maybe time lines. The winged people, the furry people, the seal-people, the people with brains so large they have towers built to hold them. There could be sidebars explaining different religions and technologies. You know, like a good science text book. It would be cool. (Ha! Arwen informs me there is such a thing.) I also wonder if the discussions on evolution and pre-genetic “human engineering” did not get this book banned in some times and places. And as was the author’s intention, this read like a history book, not a story, and he acknowledges the scale of it in his epilogue: “Great are the stars, and man is of no account to them.”
Scale! In every paragraph is encompassed a fiery idea, plot, and theme, which is wonderful to behold, yet as distant and unattainable as a star. To give it emotion and relativity, situations must be examined much more microscopically, within the idea, plot, and theme. The scale of a story can affect the quality and type of emotional impact.
