Spaceship of Ancestors

WORLDSHIP: A gigantic spacer, thousands of years from home, moving majestically through the maw of the universe. A self-contained world unto itself, pacing through the untraveled spaceways, past unknown worlds living and dead, planets where life is but burgeoning and burned-out worlds where life has become extinct. And the crew of this cosmic ship?  Slaves! Flesh-and-blood slaves to metallic-and-electronic robots! A situation which intensely irritates Pucky... who does something drastic about it in—SPACESHIP OF ANCESTORS!
