Elfland, Lunograd, trees grow tall because of the low Lunar gravity. Organisms on a large planet with high gravity should be low and wide except on Woden where the sun is energetic enough to compensate.
Adzel the Wodenite says:
"'...when I got a scholarship to study planetology on Earth, I earned extra money by singing Fafnir in the San Francisco Opera.'" (David Falkayn: Star Trader, p. 93.
Chee Lan the Cynthian retorts:
"'And by parading at Chinese New Year's...'" (ibid.)
Poul Anderson later ingeniously based an excellent short story on this dialogue.
When David Falkayn explains to a newly rescued young woman that the human discoverers of Cynthia named it after the captain's wife, Chee Lan retorts:
"'I have heard that she was not exactly his wife...'" (ibid.) -
- Falkayn blushes and glances at the young woman who, however, does not seem to be embarrassed. I should think not! Falkayn's apparent embarrassment dates this story somewhat.
Five hundred human beings, including children, were stranded on Ikrananka three generations previously. Adzel comments that such a small initial population would have lacked sufficient knowldge to maintain a modern civilization, especially since:
"'...a colony ship would not have carried a full microlibrary.'" (p. 92)
Our civilization needs more than five hundred people to keep it going. And they must also be people of widely differing aptitudes and interests. If everyone wanted to be a carpenter, then who would the plumbing let alone the brain surgery?
