Okay, so this is a request from CelestialTomatoMonkey. I got a request for some GoldenFrost and Explanation BlackIce. So, let's give it a shot!

Stories

The wind blew harsh and cold outside the workshop in the North Pole, snowflakes fluttered past the windows, and the clouds rolled by in their grey darkness like cotton balls inside a dryer. All in all, it was a delicious winter storm. Jack Frost was rather proud of it. Ten feet of snow already and it had only been a few hours. The other Guardians glared at him for causing it, but could they blame him? They called him for a meeting that didn't even concern him and expected the teenager to stay focused for the entire thing.

Bunnymund was probably the most irritated. "All that snow's gonna get in my Warren one way or another!"

"Not if you get there from inside North's," Jack retorted.

North frowned at him from the fireplace where he was discussing things with Tooth and Sandy. "You know he hates that," Bunny said, scowling down at Jack.

"Can't you just focus?" he asked, wrenching his staff from his hands so he couldn't make the storm worse. "This is important."

Jack groaned dramatically and flopped over the arm of the nearest chair, kicking his legs around. He heard the swish of Sandy talking, but didn't care to lift his head to look. He just laid there like a dead fish, unmoving, limp as a noodle.

After a while he heard North's loud stomps across the room. When they stopped next to him, he finally raised his head to hear the lecture that was sure to come. Instead he found North just standing there, smiling down at him.

Sitting up, he looked from face to face nervously, asking, "Did I miss something?"

A large, leather wrapped book was shoved into his face. "Here," North said, smiling as Jack carefully took the book, "Since you cannot focus, you can read history books." He then turned around and set several more on the seat of the chair next to him.

Jack frowned unhappily. "How will this help me focus?" he asked. North didn't answer, just nodded and smiled before walking away. Jack looked to Bunny instead.

He pointed down at the book and said, "It's got pictures. That should keep you happy." And he too walked off. Leaving poor bored Jack Frost to himself.

Sighing, he figured he may as well look at the book, if for no other reason than to look at the pictures. He pulled it open, blinking down at the yellowed pages and scrunching his nose at the reek of age on the parchment.

It started with a table of contents, starting at the very beginning. No, it literally said inside the book 'The Very Beginning'. Jack just sighed and flipped to the start to examine the intricate drawings. His eyes lit up, however, when he found that the pictures moved. Maybe this book wouldn't be as bad as he thought.

It began with what was called the first Dark Age. Shadows roamed the lands, or space or whatever it was, and nobody was safe from the fear. Nightmares seemed to happen constantly and children, though bright eyed they were, knew suffering. Until a group of heroes called the Golden Warriors came along. They fought the shadows and the demons and destroyed them.

Jack smiled excitedly as he read about how the warriors tried their hardest to vanquish the darkness, but no one was strong enough to truly destroy them. After one would be killed, another would simply come and take its place. Their fight was valiant, but it seemed to be wasted. Until one warrior came along with motives greater than the rest. The book said he had a daughter and swore to protect her and keep all the darkness away from her so that she could live a happy life. And with his daughter always in his mind, that warrior vanquished the darkness and trapped the last remaining fearlings into a cage of golden light.

He almost cheered when he saw the picture of the warrior standing proudly before a writhing cage of darkness. The book then spoke of how this warrior's noble victory brought about the Golden Age. Life was wonderful, joy spread, and nightmares never happened. The greatest warrior ever known saved them all from terror, but at a price to himself. He had to guard the shadows alone, because no other man was strong enough to do it. And at first, he proved that he was. He guarded the cage every day every night, ignoring the attempts of the fearlings to barter their freedom. He stood strong.

But even he was not perfect. Days upon days without a break took their toll. The warrior longed to see the daughter he worked so hard to protect. Years went by, and finally he was tricked by the fearlings. By taking on the form of his daughter, they tricked him into releasing them from their golden prison. And as soon as they were free, they attacked the warrior and killed him.

…

…

Jack stared down at the book. The image of the warrior being eaten alive by the shadows… It was horrifying. Swallowing, Jack lifted his head and looked at the others. None of them noticed his distraught face. How… How could the greatest hero to ever live lose like that? And nobody helped him? He fought so valiantly and no one ever offered to give the guy a break once in a while? He gave them years of peace!

Flipping back a few pages, Jack just stared down at the picture of the warrior. Standing so proudly before the cage of nightmares. He truly looked like a hero. His face was long and slender, but strong and chiseled. His eyes were a bright gold, just like the suit of armor he wore, and his spiked black hair swept up and out behind his head almost like feathers on a Native headdress. He looked like a king.

Looking back up at the others, Jack asked, "What was his name?" He interrupted their entire conversation, dragged their attention back to him, and left them all confused as to why he suddenly spoke.

Finally one of them spoke. North. "Who?" he asked, looking absolutely baffled.

"The Golden Warrior," Jack replied, "The one that saved everybody from the darkness. What was his name? The book doesn't say it."

"Ah," North said, nodding, "Name vas Kozmotis Pitchiner. 'Is daughter vas named Seraphina."

"Did he really die?" he asked.

Sighing, North said, "Well, yes and no. He lives now, but not as Kozmotis anymore. His daughter became Mother Nature, and he…" He exhaled softly and said, "It is said that after the fearlings were freed they possessed the body of Kozmotis and he voke as the King of Nightmares…"

Jack's eyes went wide as saucers. "Pitchiner… Became Pitch…?" he whispered, staring in shock at the drawing of the brave man. North nodded.

"If you keep reading the books, they go on to tell you about all the terrible things Pitch did," Bunny said, hopping over to the chair and picking one up to hand to Jack, "He brought about the coming of the Dark Ages."

"But he brought the Golden Age!" Jack retorted, looking at the two books in confusion. Bunny flipped to a page inside that had a drawing of the Nightmare King standing on the bow of a dark ship, destroying stars and planets and lives. Comparing that image to the once proud warrior saving everyone made Jack's head hurt.

"I don't understand…" he muttered to himself.

"Ah, just forget about Pitch an' read the rest of the books, Jack," Bunny said, hopping back off with the others to finish their meeting.

Frowning, Jack did his best to keep reading. He actually managed to finish all the books. It talked about how Pitch tried to attack the Man in the Moon and raise him as his fearling prince, but failed because of his protector Night Light. It didn't actually say what happened to Pitch after that, apparently they assumed he had died. But Jack knew better. Pitch obviously survived the battle, but crash landed on the planet that the Man in the Moon was floating over. The books then told about Sandy and how he crashed onto Earth as well. So… That meant Pitch was older than Sandy. Older than the Man in the Moon, even. Jack kept reading about how every Guardian came to be.

Tooth was chosen, she apparently was a Queen before that, and North and Bunny. The books also told of how the Man in the Moon chose Mother Goose to read stories to children. Jack had heard of her but never actually met the woman. And of course they also mentioned Seraphina, although now she was being called Mother Nature. They showed an image of her before and after, and honestly, Jack liked what she looked like before better. She had long black hair and big gold eyes, just like Kozmotis. When she changed, her eyes became a green color and her skin took on a green tint. Flowers and vines and other plants grew from her hair and her clothes became plantlike as well. Jack didn't like it. She was prettier before.

After reading all the books, sure Jack had answers about most everything, but Pitch… The most interesting part of the story was still the part about Kozmotis saving the universe from the darkness and then being consumed by it. It confused him, but at the same time it interested him beyond belief. The man Pitch once was… was inspiring. He had been a hero… And then he just… Destroyed everything he worked so hard for…

He flipped back to the picture of him and just stared. He wished he could have met him… Or helped him… Stopped Pitch from ever existing… Kept everyone safe…

Lifting his head back up, Jack could see how dark it was outside. Night had obviously fallen, but the others just weren't done talking. He figured he could interrupt them again, because hey, last time they had actually helped.

"Did any of you get to meet him?" he asked. They all looked at him like he was crazy.

"Meet who?" Tooth asked.

"Kozmotis," Jack said, "I want to meet him."

Now Bunny was staring at him like he had three heads. "You can't meet him, Jack. He's dead. Pitch killed him, remember?"

Jack frowned down at the floor. Bunny had a point. "Well… Can I keep the book anyway?" he asked, closing it and holding it close to him. North nodded and Jack got up and grabbed his staff. He flew off after that. If he couldn't meet Kozmotis, then he'd just read the book… That should be enough…

For weeks he read the book over and over again. He even showed the book to Jamie, although he was confused as to why. The now teenage believer didn't see why Jack was so worked up over it.

So, Jack sat by himself, staring down at the same picture for the umpti-hundredth time. He touched his fingertips to Kozmotis' jawline. He imagined feeling flesh instead of paper. The flesh of a hero who would finally be able to stop all the fear and the darkness. It would be ironic for the Nightmare King to bring about the return of the Golden Age. But it would be a wonderful irony, not the terrible kind that happened when the Golden Warrior brought about the Dark Ages.

He remembered hearing Pitch talk about the power he had when the Dark Ages were going on. Would Kozmotis have been happy about that? No- Jack could figure out that much. He would have been furious to see all those children suffering from what he tried to protect his own daughter from.

Pitch had been possessed by the nightmares… That's what North said. Nightmares had taken over his body…. Jack smiled at the drawing of Kozmotis. He must have been very brave to stand guard in front of something that he knew could take control of him.

So… If he was a living Nightmare, did that mean he had nightmares constantly? Or did Pitch have…. Jack stopped himself in his train of thought. A living nightmare…

The doors to North's workshop flew open with a burst of frigid air. The yetis and elves and shrieked at the icy wind freezing to their bodies. North spun around to gawk at the intruder. Jack stormed into the room, shoving the book right in North's face as he shouted.

"North! You said Pitch was possessed by Nightmares, right?! So, that means that Sandy could turn those Nightmares back to dreams! Sandy could bring Kozmotis back! We could have another Golden Age! All we need is Sandy!"
