You're romping through them, aren't you
Glad you liked this one - even more than most people did, it would seem. I'd agree chapter 7 (Y'Ghatan) was probably one of the best single chapters in the series so far.
I've always thought the moon would come to have a big part in this series, even from the very beginning, when Apsalar mentioned how powerful it is. The CG didn't come from there though - the Jade Giants which crashed into it came from the rent that the CG ripped when he fell, so why would it be further away than where he came from in the first place?
As for Kalam... well, yes. Speculation abounds with that one, but just imagine Rallick, Vorcan and Kalam working together for the Azath... scary thought.
