The Carver of the group, the one capable of manipulating the ground, began doing something. He created a massive crater in the middle of the asteroid by carving chunks out of the crater and moving them elsewhere.
He didn't take away part of the ground but rather morphed it. The lip of the crater was made by removing the matter that would otherwise be inside of it.
Ning moved closer to the group of 6 to see just what was happening.
The Carver didn't stop moving at all. He continued working, making the crater bigger and bigger.
Ning sat by the side of the crater and watched.
At some point, the Carver had moved from making the crater, and instead added onto the lip of the crater, making large walls grow out of it.
The crater was now about 30 meters across and nearly 15 meters deep. Instead of being in the shape of a bowl, the crater was more in the shape of a pan. It was mostly flat at the bottom.
