A perfect disguise

Severn, the Manipulator set forth a plan. Calling one of His followers to His side, He bestowed upon them the task of luring Malorea, priestess of Auresae, away from Auresae's temple. Severn assisted His follower by completely changing their form to become that of Willem, Malorea's long-dead husband. Thus this \Willem\ managed convince Malorea to leave the temple, much to the distress of her Lady's followers, and led her to a nearby forest. Severn then appeared, thanking \Willem\ for His good work, and whisking Malorea away right in front of Saradin, a follower of Auresae who followed the two. With Malorea now in His clutches, what sinister purpose does Severn have for Malorea?
