As he saw the librarian enter, he sensed a strong emotional conecction to...someone, closeby. Darth Fulgur decided to keep her away as leverage against the Jedi, crude, perhaps, but he needed a way out of here. So, using a Force suggestion from his perch, he put her to sleep and hauled her into the rafters. Suddenly, he heard footsteps, loud and hurried, coming down the stairs. He grinned maliciously as the armored Jedi ran in, lightsaber in hand, yelling at the apparition he had created.
As the Jedi leapt at the illusion, Darth Fulgur dropped down, lightsaber ignited, and sent a bolt of lightning at the Jedi.
