Apart from chapters 1 to 7 (all posted at my site) the other stories either run prior or concurrently with the main storyline. The Gyst won't be entering into the main story arc until after the Axis War is complete while the Xhali/Jazta arc won't become involved until near the end of the Fendalen/Terpla'n War. The Pulurtan background story arc is complete and they won't reappear until the start of the Pulutran War.

The first chapter of the Tzel provided background for that race while chapter 2 is set between Terpla'n chapters 4 and 5. For the Hokum, their arc starts near the end of Terpla'n chapter 4 and is running concurrently. This leaves the Cazov, with their chapter 1 setting their background with the conquest of the Gander and Ahlon. Chapter 2 will have them appear at the start of the Fendalen/Terpla'n War and will run in conjunction with that storyline.
