Arsenne, when you were looking where to hop into the water, you spotted a canoe off the western edge of the dock, 10' below the waterline (on the bottom). While .... interesting? Arsenne is far more into the shiny objects of Thickness' cleaning magic, seashells, and healing people.
That is when Mr. Arvodair calls out, "Hey! The colony boat is underwater by the dock here. I'll pull that up while the rest of you look around."
