Nina looked uncertain when asked to make light. "I've never done anything lasting before," She mumbled, but held her hands out in front of her anyways and concentrated. Flicking her hands once, a ball of fire formed between her hands, but lost it's stability and flared out. Another flick, and crackling lightning made a cat's cradle between her fingers, but it didn't give off much light. Finally, on the third attempt, a ball of glowing light flickered like a torch flame between her palms, which she held out to light the way. 

"This would have been easier if someone had thought to pack a torch going into a cave." She mumbled, staring at the ball of light and willing it not to go out.

When they were attacked, Nina was helpless holding the light, not able to throw any other bolts while she had one frozen in mid-creation.
