Every woman who had given birth to a living child now had a third eye at the base of her skull. The eye tended to be quite small and light sensitive. It worked like picture in picture; when the little eye was open its perception appeared in miniature within a bubble lens, hovering like a sprite above the normal field of vision. . . As new mothers had their babies, so too did they grow a little wrinkled eye. As mothers lost their children, that eye closed and became a horny callous.
