Galactic Civil War rages across the galaxy. Darth Vader, seeking the throne, had trained a secret apprentice, Darth Caezar to help him challenge the Emperor. After the Empire destroyed Alderaan, Vader struck down and destroyed the Emperor. Now Vader and Caezar must consolidate their power and build the military while staving off the Rebels and other rising galactic powers. They must retain order and bring peace to the Empire. The Sith will rule the galaxy once more! Plenty of new units, heroes, planets, etc. in this new take on the Star Wars saga. This is Vader's New Order - Empire surrounded.
I gave the Mandalorian warriors new models that look like actual Mandos now. They will be recruitable by the Black Sun, of course the Mando clans, and maybe the Hutt Cartel.
