If there had been large amounts of Dark Matter between galaxies, The Great Voyage would not have been so difficult. Unfortunately, there was none.
The gravitational effects of Dark Matter meant that it would gather in regions of great gravity. According to the observations of the Level Six Civilizations, although Dark Matter enveloped the entire Milky Way Galaxy and covered a larger area than it did, it only extended somewhat farther than the region occupied by Bright Matter.
Judging from the Milky Way Galaxy's rotational data, Dark Matter extended only about a hundred thousand light-years beyond the visible Milky Way Galaxy. Beyond that, there was no matter.
In other words, after replenishing their materials here, The Great Voyage Organization could continue for another hundred thousand light-years and have one more chance to resupply. But that resupply would be extremely difficult, because the Dark Matter at the very edge was bound to be exceedingly sparse.
Now, the fourteen Level Six Civilizations each occupied a stretch of starry sky and mined resources on a massive scale. All kinds of ships traveled back and forth through space. Planets were blasted apart directly with weapons, while stars were drained by enormous resource-extraction platforms.
At that moment, every star in the entire starfield fell into its darkest hour.
The frenzied extraction by the Level Six Civilizations made their luminosity change again and again. They went from bright to dim, then swelled, and finally went dark.
The Level Six Civilizations used the power of technology to enact myths and legends here. Moving mountains, filling seas, plucking stars, and seizing moons were effortless to them. If Primitive Civilizations saw their mad extraction of stars, they would surely believe it was Yi Shooting the Suns.
The matter from stars and planets was frantically drawn in by the fourteen
