Ladon System
Pax Dracon

"Due to the global scale of the conflict, my people sent one of our Legions to assist in the war effort.  The insurrectionists, or the Chosen as they called themselves, were defeated after a few Standard Years of combat, but not before they attempted the unthinkable..."

The Emperor sighed as he looked at Teemas.  "Because they were on the brink of defeat, their leaders had concluded that they as well were weak and impure, unworthy of joining the 'Mighty Beings from Afar'.  They attempted to set off lethal nerve toxins in major population centers in an effort to purge the cosmos of what they viewed as their race's impurity.  Most of them were found and disarmed, save for the one in the planetary capital.  King Ajakis, seeing no other option, took the bomb it was contained in aboard a shuttle and raced into orbit just as it detonated."

"His sacrifice saved countless millions.  To honor his actions and his dream of bringing Yapath to the stars, the Yapatha government requested that their world become an autonomous Protectorate."
