used their Force powers to haul the heavy machine along the winding corridors so Jaina could work on it in her room far into the night.
"Hurry!" Jacen said, feeling the urgency grow. Jaina squirmed backward out of an opening in the intake pipe. Her dark brown hair was straight and simple, tied back with a string to keep it away from her narrow face. Smudges of grease made hash marks on her left cheek.
Though her shoulder-length hair was as rich and thick as her mother's, Jaina never wanted to take the time to twist and tangle it into the lovely, convoluted hairstyles for which Princess Leia had been so famous.
Jacen extended his hand to help her to her feet. "My crystal snake's loose again! We have to find it. Have you seen it?"
She took little notice of his words. "No, I've been busy in here. Almost finished, though." She pointed down at the grimy pumping machinery. "When this is all done well be able to install it in the river next to the temple. The flowing water can turn the wheels and charge all of our batteries." Her words picked up speed as she began to talk. Once Jaina got started, she loved to explain things.
Jacen tried to interrupt, but could find no pause in her speech. "But, my snake-"

Jacen stopped her. "Jaina, why are you spending all your time doing this? Don't we have dozens of permanent power cells left over from the old Rebel base?"
She sighed, making him feel as if he had missed some deeply important point. "I'm not building this because it's useful," she said.
