This is a story about magic and where it goes and perhaps more importantly, where it comes from and why, although it doesn't pretend to answer all or any questions.
It may, however, help to explain why Gandalf never got married and why Merlin was a man. Because this is also a story about sex, although probably not in the athletic tumbling, count-the-legs-and-divide-by-two sense unless the characters get totally beyond the author's control. They might.

(Terry Pratchett, Equal Rites, 1987)
