From the introduction:
The Galactic Republic has been the presiding governing body throughout the galaxy for nearly twenty-five millennia. It was comprised of hundreds of thousands of star systems and thousands of sentient races. Those who served the Republic faced many adversities over the millennia. The Clone Wars were no different. After a thousand years of peace and prosperity the Republic had become corrupt and decadent. There were those who came to realize this deterioration of Democracy and pledged to break away from the crumbling government. When this splitting came to all out war, the Republic was ready to answer their enemy’s call to arms with their Grand Army of the Republic. Below is a chronicling of those who remained loyal to the Republic and for what it stood.
