A new dragon roared. Except, this one sounded friendlier and familiar. Toothless. He finally found Hiccup, but he was frightened when he saw him twitching uncomfortably on the ground. What on Earth was wrong with him?

Even outside the dream world, Hiccup had his hands up against his ears. "Stop! Stop!" he shouted at the Light Dragon.

Toothless roared again. He bumped his black forehead up against Hiccup's. He hated seeing him so scared.

Finally, the dragon's warm touch pulled him out of Niflheim. His eyes snapped open. "Toothless! What are you doing here?" He was completely drenched in sweat. "What WAS that?" His legs shook. Hiccup buried his face in his hands.

Whining, Toothless plopped down next to him. His ears stood straight up, and he set his head down on Hiccup's lap. He waited patiently until he calmed down.

After a few minutes, Hiccup unburied his face. "I'm sorry, bud. I just... I don't know if the Light Dragon is friendly anymore." He peered down on his legs and groaned when he saw he did not have his left one anymore. That's all the vision was–just a dream.

Toothless sniffed the stump. His big green eyes met Hiccup's.

"Yeah, yeah, I know," he chuckled, "I'm always losing my legs." Luckily, he usually kept a spare one with him. Hiccup undid the leather satchel on Toothless's brown saddle. There were two spare legs in it. He picked one and put it on. It pinched him a little bit, but Hiccup was used to it. He tapped the metal part on the ground a few times to test the leg.

Toothless's eyes then caught the crystal he found. Hiccup had it up against another rock. Instantly, he looked curious.

Hiccup saw what grabbed his attention. "Oh, this." He picked up the crystal and held it up to his dragon's face. "Isn't it gorgeous? I found it behind a rock. Look what it can do." He moved the crystal around a little bit but was shocked when he saw that it no longer unleashed dots of light energy.

Toothless gave him a confused look.

"What?" Hiccup asked. He batted the stone with the palm of his hand. "It was working earlier. I'm serious, Toothless. It can do something that's similar to the Dragon Eye."

Toothless's gaze moved to the bruise forming on his friend's temple. He must have hit his head a little bit when he fell, causing him to go a little cuckoo.

Hiccup wanted to argue with him, but he stopped himself.

From out of nowhere, he heard, "Hiccup!" behind him. It was Astrid. She, his friends, his friends' dragons, Gobber, and Stoick managed to track down the underground chamber. They got in from a secret entrance Hiccup would discover later.

The party hurried to he and his dragon.

Toothless smiled his signature goofy grin. He wagged his tail and joined the other dragons.

Hiccup rose to his shaky legs. He hid the crystal behind his back. It now faced the river. His friends pounded him with questions.

Astrid grabbed his shoulders and shook them a little forcibly. "Are you hurt? Please say you're not."

Gobber bumped her out of the way with his hip. He pointed at Hiccup's leg. "Do you need another leg? You stumbled a little bit."

Next, Stoick pushed him off to the side. He crossed his arms and said in his booming chief voice, "How did you and Toothless find each other?" He spoke so loudly that the stalagmites shuddered. They looked like they would fall.

Ruffnut smirked. She wrapped her arm around Tuffnut's shoulders and pulled him close to her chest. "I have to say that if it wasn't for Tuff and I's sixth sense, you'd be trapped down here forever. Eh, bro?" She gently rapped his helmet.

Snotlout, who didn't like being ignored, slapped his hands to his cheeks. "So, we're all just going to gush over Hiccup here and not even worry about little Snotlout–who nearly fell into quicksand?"

Fishlegs smiled. He patted Hiccup's shoulder. "Hey, we've got to look after our one-legged Vikings."

Hiccup could only say one thing. "Sure." He sometimes didn't like getting reminded that he only had one leg.

His friends and father kept gaining on him. Toothless played with the other dragons. They cheerfully roared at one another. The dragons kicked up dust with their game.

Hiccup could not take the stress of so many voices yelling at him. He hated being treated like a chief when he obviously wasn't one yet. To make matters worse, he heard it.

SCREEEEEEECH!

Hiccup's head throbbed, especially the temple where his bruise was.

"No! Not again! Stop!" he yelled.

The Light Dragon refused. Oh, how he enjoyed torturing him psychologically.

Hiccup fell to his knees. He shook the old noggin as an attempt to get the dragon out of his mind. The crystal flipped out of his hand and landed next to his ankle.

Stoick quickly shut everybody up, "Stop!" It may have been against his will as chief, but something was clearly wrong with his son. There was something in his head. He kneeled to him, asking, "Hiccup, are you okay?"

"Am I okay?" What a dumb question. Hiccup grabbed Stoick's shoulders. "Please, Dad. Make it stop."

Gobber, his friends, and the dragons gave him a weird look.

The young man seemed to suffer from a nervous breakdown. "Stop, stop, stop!" he repeated. He quickly left the care of his family and friends and made his way towards the river. He constantly banged his peg leg on the ground and threw smaller rocks in all different directions. "Stop!"

No way. The Light Dragon was having too much fun. He also just needed a way to get Hiccup alone.

Stoick noticed the crystal his son dropped. "Wait, it can't be–!" He picked it up. Stoick saw his reflection in the stone's clear surface.

Astrid and Toothless rushed towards Hiccup, scared for his well-being.

He stopped at the riverbed and carefully studied the flowing water. Up close, he saw that the river itself was crystal-like: slick, shiny, and clear. The Light Dragon's heterochromatic eyes appeared from deep within it. They moved in a circular motion. The power was similar to something a Tidal class dragon could do.

"Come with me, my boy. I will take you to a place where the fairies sing," cooed the beast.

"Hiccup, stop!" Astrid grabbed her friend before he could commit his own suicide.

"If you won't join me, then I'll have no choice but to use force," threatened the Light Dragon.

Hiccup was the only one who heard him and saw his eyes. After all, the dragon wanted him and him only. He also felt a strange connection when he was around the boy.

Stoick tried to break the crystal. He banged it on the rocky ground and stomped on it. However, like a cockroach's shell, the stone never shattered. The sunlight inside it was just too powerful. If Stoick couldn't break it, then he had no choice but to knock out his own son. That would at least free him from his breakdown.

Gobber even asked what Stoick was thinking. "Do you think we should knock the boy out?"

The dragons and Hiccup's remaining friends' ears perked up. Ruffnut and Tuffnut were immediately up to the task.

"Oh yeah," Ruffnut said. She punched her left palm. "I've always wanted to play Bat the Nutt with Hiccup."

Stoick was not pleased about his decision, but it was for Hiccup's own good. He wrapped his meaty fingers around the crystal and hid it from the teens' view. Rising to his feet, he turned to the twins. "We have no choice."

"Aw, sick!" Tuffnut and Ruffnut said at the same time.

"Oh, I can't watch this," Fishlegs mumbled. He turned his back to the party and hid behind his hand.

In the meantime, Ruffnut and Tuffnut sprinted towards Hiccup, Astrid, and Toothless.

"Hiccup, please. You need to calm down." Astrid put her hands under his arms.

Hiccup fought her. "No, the Light Dragon, Astrid. The Light Dragon promises he'll take care of me." He attempted to dive into the river, but Astrid pulled him back.

Ruffnut and Tuffnut reached the group just in time. Without warning, Tuffnut lifted his fist. He punched Hiccup across the face, knocking him right out of Astrid's arms.

"What the–?" she asked.

Tuffnut's punch, though, only stunned Hiccup. He stumbled and shook out his head.

"You call that a punch? I'll show you how it's done." Ruffnut delivered the second one. Hers was the one that knocked Hiccup unconscious.

He fell onto his front on the cavern floor. His arms were parallel to his hips.

"Ha! Ha! That's ten points for Ruffnut!" Ruffnut's feet shuffled under her at incredible speed.

"Showoff," Tuffnut grumbled.

Toothless hurried to his friend. He licked his cheek, but Hiccup did not stir. He wrapped him in his large wings to protect him.

"What the–?" Astrid asked again. She glared at the twins. "What is wrong with you two?"

Luckily, Stoick's voice saved them. "They had to do it." He, Gobber, the dragons, and the rest of the friends reached them. For some reason, the cave seemed to grow colder by the second.

"What do you mean?" Astrid angrily asked the chief. "They hurt him, and you're just going to let it slide?"

"Because it was the right thing to do. We had no choice, Astrid. Look what Hiccup found." Stoick took Astrid's shoulder and turned her in his direction. He opened his free hand, revealing the crystal. Being near Astrid–the other hero–it glowed again. The light-yellow light lit her face like the flame of a torch.

Astrid's eyes widened. She reached for the stone. "Si-Sir, what is that?"

Stoick tightened his grip on her shoulder. "It's one of Naga's crystals."
