Because they were in an incomprehensible reality, they eventually decided to follow Glok, especially after witnessing firsthand the scenery seen by the person in front of them. Although they didn't know why this was happening, they could now remain calm without worrying about getting lost or disappearing. They just needed to ensure they kept walking together without anyone being left behind.
They didn't realize that they were no longer on the surface but rather on the ceiling of the shell, walking as if gravity never existed. Naturally, they didn't notice this as the surroundings kept changing, and they had to trace their way back while walking backward, following a rope that was also starting to thin out.
Glok could only hope the rope was long enough for them to reach the desired place, because if not, they would have no way back except by remembering every path and turn, down to the smallest detail. One mistake, and they could be lost forever inside.
