Planet Terra (Earth)

The blue-and-white jewel of inhabited worlds, Earth orbits within the habitable band of its star, its surface a complex tapestry of continents and oceans where billions of lives thrive under the same sky. To the Doctor, its cities and cultures represent civilization’s fragile summit; to Queen Xanxia’s spanning force, its people are targets to be unmade in a single calculation. The bridge crew’s instruments confirm its coordinates as the intended destination, its presence evoking horror rather than wonder in the Doctor’s plea.
