Kallan are the most populous race in all of Vernex Keep. They are the ones that created Parliament, they produced the economy that everyone works within, and they were the ambassadors that made all the races sit down and talk together in the first place. And getting the Limthrakk to talk together and not down to everyone was enough of an accomplishment in and of itself.
The Kallan military merged with Parliament. The Registry of Enforcement is a grounded military, serving as soldier police on every Parliament planet in the galaxy. They have no authority during space flight, but on the ground, they are police, soldiers and investigators. Other races have joined their ranks, but the idea came from the Kallan.
Now Kallan work all walks of life: business, religion, government, criminal underworld, etc.
