Ignoring her question, Zacar pressed a thumb against it and the ball expanded, hovering higher in the air. From the way it vibrated slightly, she would expect a humming sound, but it was completely silent. Zacar touched a second ball, and it expanded, as well. Zurian walked to the door at the front entrance and pressed his hand against the panel. Although braced for the cold wind sweeping in, Natalie thought she would freeze on the spot. Even her hair ached. The eight balls floated gently out of the cave.
"What are those?" she repeated. "Where are they going? What do they do?"
Zacar said something to Zurian, who went to the door and started to install something.
"What's he doing?"
Still ignoring her questions, Zacar sat down a little away from her. One moment his hand was empty and the next his sword appeared. He proceeded to rub a purple sponge over the blade of his sword.
"How do you do that? Make your sword appear?" she asked.
