Check out Chapter 27 here.
Lapis, Patch, Brander and Dagby rush to prevent the evacuation of the coder and retrieve the khentauree research they flee with. Oddly, the markweza is not part of the flight, and more information about who and what underpins the events at Ambercaast comes to light through him.
Chapter 27 is the penultimate chapter! The Ambercaast arc ends in two weeks with Chapter 28, then Lapis and crew move on to Knavish Canto: The Jilvayna Chronicles Book 3.
