In the end, the group spent another ten minutes finalising their plans moving forward. Grace was leading by about 5 metres. She was much faster and could take more round about routes to fully inspect the area and make sure there was nothing for Kat or Skye to run into.
Kat followed behind, keeping her body low and her tail in close. The original plan of having Kat hover quietly behind was dropped when she realised just how hard it was to stay airborne but below the walls. Her wings wouldn't lower her much even if she brought up her legs and the position was really uncomfortable.
Finally Skye brought up the rear. She didn't really have any special role but her experience in adventuring allowed her to move across the ruined stone with more ease then Kat. She was also quick to point out the issue with Kat's tail.
So did anyone suspect it? I didn't want it to be a major surprise, but for people paying attention I'm pretty sure I left more than enough clues.
