第2章 | 地精佩比相助（上）
The castle's library was dark, but the king knew what he was looking for: an ancient book filled with knowledge from centuries past. When he found it, he pulled it from the shelf and quickly flipped through the pages to these section he needed. In it was a drawing of a troll, which seemed to be holding the northern lights in its hands. In front of the troll, a wounded human lay quiet while the troll used the magic of the northern lights to heal him. The king turned the page and spotted a crumbling document tucked into the book. He carefully unfolded the yellowed map.
Wasting no time, the king and queen threw on their cloaks, bundled up their daughters, and ordered that the horses be saddled. The royal family hurried away from the castle. The queen traveled on her own horse with Elsa, while the king held Anna in his arms. The horses thundered up the mountain path.
Kristoff and Sven were walking down the rocky mountain path under the bright glow of the northern lights. But as the rumble of hooves filled the air, they moved aside, wary of the approaching horses. They watched the riders gallop past, leaving a trail of ice behind them.
Curious, Kristoff and Sven followed the travelers to a ridge above a mountain valley. The two hid behind a rock and watched as the horses whinnied and came to a stop.
The king and queen dismounted. The king held a young girl to his shoulder; the queen held the hand of a slightly older girl.
“Please, help!” the king cried out. “My daughter!” The hillside appeared empty at first. Then a pile of rocks rolled down the hillside. Suddenly, the rocks unfolded themselves into legs and arms and stood up, revealing themselves to be small gray creatures — they weren't rocks at all! “Trolls, ” Kristoff whispered to Sven.
At that moment, a rock next to Kristoff jumped up, turning into a short troll woman covered with moss. Her name was Hulda.
“Shush, ” Hulda told Kristoff absently. “I'm trying to listen.” Then, startled, Hulda looked more closely at Kristoff, realizing for the first time that he was not a troll. Her face broke into a grin, and she reached out to give Kristoff and Sven big hugs. “Cuties!” she said, laughing.
In the valley, the king stood with his daughters as Pabbie, a very old troll, made his way through the crowd to gaze at the princesses.
First he looked at Elsa. “Was she born with the powers or cursed?” he asked.
“Born, ” the king answered. “And they're getting stronger.”
