From the post:
Three powerful Force users will soon make their Imperial Assault debuts in the three Ally and Villain Packs coming with the Heart of the Empire expansion. But for all their strength in the Force, there's not a single Jedi among them.
Maul Villain Pack
Emperor Palpatine Villain Pack
Ahsoka Tano Ally Pack
Associated with the Heart of the Empire expansion, these Ally and Villain Packs transform your campaign into a more dynamic and tactile experience. With these packs, you can replace the tokens for Maul, Emperor Palpatine, and Ahsoka Tano with detailed plastic figures. And their new side missions afford you greater use of your Heart of the Empire map tiles, even as they provide you the opportunity to bring these powerful Force users directly into the action of your campaign.
