They were so close to the fortress that was high at the top of the giant tree that some of them wanted to climb up without the others and see what was up there at that very moment. But Ray had made it clear that it wasn't going to be an option.
They either all went up together, or not at all. It was clear that Monk and his party had reached the fortress before them. Originally, for losing the duel, if they had agreed to the terms they would have had three extra days to investigate. Due to their quick pace and the nights rest they would be taking tonight, they would only be a single day behind their group.
Keeping watch for most of the night was Noir. Ray trusted her a lot more than he did the others, and she would always come to him at the speed of light when there was trouble. Due to Noir being placed in the system most of the time she was well rested, so staying up all day and night would be easy work for her.
