Where is Pok’along

It the latest efforts in writing the fourth book of the Series I run into the question. “What should the 4 main characters be doing? They are in a cave far below Noso land and have just surfaced from traveling through an underground river to enter a new portion of the cave. I really had to think to get Charlie and Hoot through (Birds don’t swim you know). They have a purpose for being there and why do they have Tarifess with them? Something to think about. Remember book #1.

If you have been in a cave and wish to express what you saw that I might use within this new book. Post your idea and I’ll give it consideration.
