It was precisely because they had discovered this phenomenon that, while traversing the Four-Dimensional Space Shard region, The Great Voyage Organization actively searched for sources of light.
All civilizations realized that although the odds of finding matter within these Four-Dimensional Space Shards were low—after all, there was little matter between two star systems—if these Space Shards were truly the result of war, then one side must have been the target of the attack.
That meant matter could exist within these Space Shards: warships, various vessels, and technological constructs belonging to the attacked side.
Thus, if a Four-Dimensional Space Shard fell into an area that had originally contained constructs, it would emit light into Three-Dimensional Space, just as they had observed in the collision-based Dimension Waterfall Experiment.
Then, as long as they found those lights, The Great Voyage Organization could obtain energy supplies here.
The search for light sources within Four-Dimensional Fragments had begun the moment The Great Voyage Organization decided to cross this region. Unfortunately, the area was simply too vast, and the crisscrossing Four-Dimensional Space Shards obstructed their view, making it difficult for the Great Fleet to search using telescopes alone.
But Heaven rewards those who work hard. After a thousand years of searching, The Great Voyage fleet cluster finally received good news from a Silver Heart Civilization probe: it had discovered a source of light.
The light source lay to the side of The Great Voyage fleet and required them to travel roughly ten thousand light-years, circling behind a Four-Dimensional Space Shard.
This discovery gave The Great Voyage Organization a brief opportunity to replenish supplies while crossing the Four-Dimensional Space Shard region.
It was called brief because the light source lasted only a little over a hundred years before vanishing.
Combining Four-Dimensional Space data with various hypotheses, scientists
