"...Is this the Miniature Galaxy that the Sentry created?"
Looking at this very familiar thing, the Voyager scientist couldn't help but ask.
Judging from the design style, this Miniature Galaxy was very similar to the Miniature Galaxy that humans had left behind in the Milky Way. It was so close to being recognized as a relic of humans.
It was a sharp-eyed scientist who discovered the words of the Sentry on the surface of the Miniature Galaxy and determined that the technology was different from some of the details after construction. Only then did he confirm that this Miniature Galaxy was not a human creation.
