Obi-Wan shook his head, trying to clear his thoughts even as he resisted. The Force was strong, fairly pulsing throughout and around him. He desperately reached for its strength, balancing himself in the Force even as he tried to step back, away from the Senator.
The Senator growled, and Obi-Wan suddenly saw what he was facing. His hand flew to his lightsaber, weilding it before him in an instant.
"Foolish pup," the Senator -- the Sith Lord -- sneered, and the harsh red glow of another saber filled the darkened room.
Obi-Wan reached inside himself, and sought the calm which would allow him to face, if not survive, his battle.
Obi-Wan wins the fight.
Obi-Wan loses the fight.
