This is a baby chick, not a dragon. So what was it doing in the dragons’ cave?

Everything little Lucy knows, she learned from her beloved mentor, Space Cadet Henrietta. Brought up under the enthralling tales of Henrietta's revelation as to her origins and consequent quest for her true family, Lucy, too, believes that she is a space chicken, dropped into a dragon cave as an egg for reasons unknown. Though frozen as a hatchling—well, as a chick—Lucy is both creative and remarkably adept at more mechanical occupations, and it was through her inspiration that the tiny flock is working to build an eggship of their own. Let the disbelievers go their own way, Lucy says; they'll be laughing out the other side of their snouts when the great eggship comes back.
