Chants of Sennaar EP14 -- These People are...Bards?! We Figured Out the Colon Glyph! 

With very little of the third floor left to explore, Matt and Carl make some crucial progress with the language of the people here who are called the "bards."
Also, it seems the sewer maze has more to offer, so Matt and Carl must return to the underground labyrinth.
