Hiccup never told Jack how he ended up under Pitch's wing all those centuries ago; the winter spirit never asked. Darkness itself had offered him redemption and granted him special powers, gifts that only he possessed. Pitch trusted that Hiccup would never leave, and Hiccup had faith that Jack loved him too much to leave. They were the perfect trio, spreading fear through cold winter nights, darkness, and destruction. The Dark Ages were their years of paradise, full grown men turning on each other in the face of fear, slaughtering themselves before they could get to families cowering inside run down building and villages. Pitch often left them to their own devices, scheming other larger plans while his lover fearlings caused mischief under the cover of shadow.

Hiccup and Jack knew better than to go looking for their mentor when he didn't come back. He would leave for days, sometimes weeks at a time. But when months turned into a year they knew something had happened, and they were safer not sticking their noses in it. They were immortal, he would come back eventually. The two cut back on the mischief, picking a town and a dwelling with a single person inside, scare them until they were practically brainwashed. They watched up close from the sidelines as people got brave enough to start protests, marching through the cities and the suburbs and fighting for their rights. No longer subdued by the fear that had been unleashed upon them in the guise of white men, the world around them had thrown itself into chaos.

"Do you love me?" Jack asked, half covered in darkness, the other bathed in the orange red light pouring through the window from the fire burning across the street. Hiccup was perched over Jack on his knees, straddling his waist and looking down at him. They were in their normal forms, Hiccup with his brown hair and forest green eyes and peach freckled skin, Jack with his ever pale skin and ice blue irises and snowy white hair.

"Of course I love you Jack, why would you ask me that?" Hiccup responded, leaning down to lay a gentle kiss on his forehead. It had been almost a millennia since Jack and Hiccup had joined Pitch Black, so he didn't understand why this came up now.

Jack didn't look assured. "It's just, that night. I watched over you because you were just as invisible as I was, you were important to me. You led me through the forest baited me, gave me to Pitch in exchange for power. I just-"

"Shh Jack, hey. I may not have loved you then, but I've loved you ever since. Pitch wanted you and you wanted me, and that brought us together. We've had so much fun together since my mortal life ended on Berk. So don't doubt how much I do, okay?"

The fearling nodded, hugging Hiccup's body to him. "And you still love me, right?" he asked.

"Yeah," Jack murmured into the fabric of his shirt. "Always have."

Hiccup was walking on the sidewalk in a neighborhood; this was the third city in the past fifteen years that Pitch had been gone. It wasn't a neighborhood, and his body was frozen at the age of a young baby-faced boy, so Hiccup took full advantage of it, using it to lead to older men stalking him into an alley. Jack was perched above them on the rooftops, dropping down behind them when they got far enough in. He used his staff to freeze their feet to the ground, and they immediately panicked, looking between the two as Hiccup's skin seemed to melt off (a trick that he'd perfected over the years), revealing darker, deader skin underneath, wild gold lit eyes of a monster, fire lighting up in his hands, engulfing them all the way down to his mid forearm. Jack did the same, hair blackening and eyes turning gold, ice crawling over the ground and up the walls. The men fainted with their feet still rooted to the concrete, and the boys didn't hesitate in indulging, feeding on the essence of their body until they stopped breathing.

Hiccup walked over them and into Jack's arms, and they kissed as Jack raised them up into the air, taking them back to where they resided in the city. They came in through the window of their bedroom minutes later, most of their clothes off by the time they stumbled to the bed.

This was always how they did things: find a city, pick a house with one person and sustain for as long as possible off them without killing them, and then go into the city and find a full meal, then come back home for after-dinner sex with the taste still lingering in their mouths, on their skin. When they first started doing it they usually stayed in their normal forms, considering they had opposite powers and could easily wound each other. But as they years went by, pain made it more enjoyable, more fun, and they experimented in their fearling forms, both sporting scars from the first time they had tried and didn't know what they were doing. Hiccup had three ice shards embedded into the skin of his hip from where Jack had scratched him, the winter spirit with a black burn on his lower back in the shape of his lover's lips. The learned to walk the line between safety and destruction.

Hiccup left scorch marks in the shape of his hands over Jack's shoulder blades as the winter spirit thrust into him with no preparation and nothing to smooth the way, the Jack leaving frost bitten kisses in the hollow of his neck, trailing them up to his jaw. The freckled boy moaned, baring his throat and clinging to Jack with his arms and legs, completely off the bed as he thrust back. Finally cold lips found his, and he didn't hesitate in shoving his tongue past them, writhing when teeth trapped his tongue there, fingers gripping his hips bruisingly tight. Jack shoved into him hard enough that he broke the kiss, shouting as he slammed into Hiccup, a satisfying cold exploding inside of the body beneath him. Hiccup found orgasm as Jack slid home, cum trapped between their bellies. Jack put Hiccup down and used his tongue to clean up his stomach as they bathed in the afterglow, the smaller male rolling them over and reciprocating the process.

When they were done and back in their normal forms, Jack reached over the foot of the bed and handed Hiccup his black hoodie and pulled on his pants, and they settled down for the night, the brunette curled up against the winter spirit's chest. Hiccup was a creature of fire since Pitch had granted him the life essence of a night fury, so he couldn't stay too cold, and it couldn't be too warm or Jack would get sick, hence the hoodie was a necessary thing for the after-sex cuddling.

The person they lived with now was a college student, and he hadn't really been afraid the first time Jack and Hiccup had popped in through his window. It was peculiar, but they didn't force it on him. He was a lanky kid with a light brown hair and hazelnut eyes and fair skin, with a younger sister named Sophie that came over sometimes for the weekend that had taken a liking to Jack. The two fearling's were Jamie's secret.

So it wasn't surprising that the window had been closed and the curtains drawn when they woke up in the morning. They sauntered out of the room sleepily to the sound of sizzling and the smell of meat. It had been centuries before they discovered they could still eat human food, though it did little good to sustain them; but they taste was always nice. The human heard the bedroom door click open, smiling at them as they came around the corner. "Morning guys," he greeted.

"Morning Jamie," Hiccup responded, Jack waving at him while he yawned. Jamie laughed, rolling the sausages in the pan over and checking the hashbrowns in the oven.

"You guys slept in late. Guess who's already-"

"Hiccup! Jack!" the excited little voice cut him off, and a blond human girl came barreling at them from the living room. The winter spirit caught her by the waist, lifting her in the air with an excited shriek, before shifting her to one arm and tickling her with the other. "Okay okay! You win!" she said, wiggling and rolling out of Jack's grasp.

"Morning Sophie," he said, and she rolled to her feet and hugged him.

"Breakfast is almost done," Jamie said, Hiccup nodding and going back into the room to find his pants, tossing Jack his shirt. He pulled it over his head and chased the twelve year old into the living room as Hiccup went to the bathroom for a shower.
_

In the four years that followed, Jamie's parents had passed away in a car accident and Sophie came to live with him. Eventually, when the pain wasn't so raw, Jamie moved into a three bedroom house and the four of them settled down together. The number of nights Jack and Hiccup spent comforting a hysterical Sophie when Jamie was working softened their hearts. They went out and fed less, changed less into their fearling forms, spent less time having violent sex and more time cuddling and playing with Sophie.

But peace never lasted forever.

So the first chapter was HTTYD world, the second chapter was the transition between HTTYD and RotG.

The plot for RotG picks up next chapter.
