A group of Imperial Force Adepts were deployed on Bespin along with Darth Vader when Tyber Zann, Urai Fen and IG-88 tried to escape from the floating city with a store of Tibanna gas. Two others groups of those adepts were stationed on Coruscant. The first group with their leader, a Master Force Adept, faced Tyber Zann as he raided Sidious's Imperial Museum. The second group fought Silri and her rancor as well as Urai Fen. All of these groups were defeated however.
