It Works!
What was I doing? It was like adding more cement layers at the foundation of a building to support it and prevent it from falling apart!
Any planet or moon would be formed out of rocks and ores, melted and merged together to form a unified solidified layer that would sustain heavy damage.
From the words I heard about the current status of the dark planet and moons, I knew that they got their outer layers hallowed out and filled with caves.
This was something that helped the destructive effect brought out by tough battles here and ended up threatening the entire dark planet and dark moons to get shattered.
By the layers I was now adding, bringing the rich mines of rocks and ores at the outer space here, I'd help to stabilise the entire dark moon surface, repairing part of the damage.
However just adding this layer here wasn't going to work. These pieces were all scattered and not attached together, nor to the surface of the planet.
