Once upon a time, a male Elf, a male Human, and two female Humans moved to an area near a lake. It wasn't long until a male child and a female half elf-half human were born, then that couple produced many quarter-elf children, who gave birth to more children, etc. etc. When Edward was sixteen, he met a girl of fourteen, Queen Jessica I, and a her twin sister, Queen Elise II. When those twins came to the age of sixteen, King Edward married the two of them.
