Collapse of the Republic serves as a companion piece and a sequel of sorts to Rise of the Separatists. While the latter book details the first half of the Clone Wars, Collapse of the Republic details the end of the war and the Republic. Along with a new era embraced by this new book, you’ll also find new species and specializations included within the sourcebook – all of which played a role in the Clone Wars, including the mystic Dathomirians.
Collapse of the Republic also introduces several new specializations, and offers new takes on classic tropes. For example, the Clone Wars have raged on for years, and Clone Troopers have adapted to new battlefield tactics. In the beginning of the Clone Wars, the Grand Army of the Republic consisted of identical soldiers with training along special parameters: ground combat, air combat, and officer and leadership training. Now, different factors have created slight but profound variations.
