Something of an AU. The idea is this is what would have happened if the Descendants of Jack Frost hadn't been left to their own devices when they first started showing up. That the other Descendants actually took responsibility, found them, taught them about their world and helped them set up a base of their own.
The four Heads appeared from a Tunnel, each one garbed in a cloak. It had been a week since Jack Frost had become a Guardian, and since there had been no other attacks since, they had decided to alert the Descendants of Jack Frost.
Where they were now was a snowbound fjord, far out of the way of civilisation. The Descendants of Frost were among those who chose to live outside of society, so taking on a double life would be, interesting for them. Especially since most of them likely have lived outside of here since they were little.
"It's freezing!" cried Alexander, wrapping the dark green cloak around him, despite his thick clothes.
"We all knew it was going to be cold." reminded Samson. "Let's start walking before we freeze."
In the distance they could a swirling snow storm, and even though none of them would admit it, they were more than a little daunted at having to walk through that.
Nevertheless, they kept walking.
As they approached the snowstorm, the snowflakes parted and the wind dropped around them. The four Heads stopped in surprise. Less than a metre from them in all directions was a howling storm, but in a small bubble surrounding them, everything was calm.
"They're expecting us." said Jason with approval.
"Tsar Lunar must have told them." said Alexander with a shrug.
"Or they are friendly." offered Samson.
"They haven't had visitors in 250 years." said Claire. "And most of us haven't exactly been welcoming. I think they're giving us the benefit of the doubt."
The group continued walking across the fjord, and slowly what looked like a castle made of ice came into view.
They came closer and saw two people standing in front of the large double doors, either to welcome them or on guard duty. They were in their mid teens and identical, looking surprisingly like Jack Frost, except with brown eyes and hair, with a more sloped nose and higher, more arched eyebrows.
And, as the Heads approached, they could hear arguing.
"Can't believe we got door duty again." complained the one of the right.
"Well, if you hadn't flooded the kitchen..."said the one on the left, who had a small birthmark over his right eye.
"It was an accident!"
"Sure it was." The one of the left rolled his eyes, but they were both grinning, like they'd had this kind of argument hundreds of times.
"What about the dorms? I heard what happened there." The grin from the boy on the right seemed to grow, matched by the one on the left.
"Oh, their faces!" They started laughing until they noticed the four Heads. They stopped and stared at them like aliens had just landed.
"Who are they?" asked Left in a whisper, which Alexander picked up.
"Dunno." said Right, also in a whisper. "Go get Alfred."
"You go get him!"
"You go!"
"No, you!"
Claire coughed and the two turned from their small argument to face her. "If one of you gentleman would please tell Eye O'Donnell that the Heads from the Human Order of Guardians are here, then we would be very grateful."
Once she mentioned where they were from, the twins stared at them with expressions of disbelief, and a little anger. They looked at each other, nodded and the one on the left knocked on the wall.
A small opening appeared at head height, and the four Heads could see a pair of dark eyes framed with a pair of glasses peering out.
"Password?"
"Jackie, not now." groaned Right.
"Incorrect." Jackie closed the opening and Left knocked again, more insistently.
"Who dares disturb-" Jackie never got to finish her joke, as both twins yelled in unison.
"GET ALFRED!"
Jackie blinked, then looked at the four Heads, noticing them for the first time.
"...Right."
The opening closed again and you could hear the sound of someone sprinting.
The four Heads waited patiently until the door opened again, revealing a girl about thirteen or fourteen in a t shirt and shorts. She had dark brown hair that hung loose and straight down her back and dark eyes with bright blue rectangular glasses perched on her nose.
"Alfred's in his office, can I show you up?" she asked with a clear East American accent.
"Yes, if that's alright." replied Jason, and Jackie nodded. The four Heads stepped past the twins on door duty and into the entrance hall.
Naturally it was made entirely of ice, although there were a few rugs and tapestries to break up the white and blue monotony.
The four Heads instantly had some trouble on the ice, and Jackie failed to hide an amused grin as they slipped around.
"Alfred's office is upstairs." she said, gesturing to a wide set of stairs in the centre of the hall. Take your time to get up there." she added, walking up the icy steps with practised ease. Claire took to the air and Samson decided to be nice to the other two Heads and lifted them up on a cloud of Dreamsand.
At the top of the stairs Jackie stood with her hands behind her back and her head tilted to the side as she watched them. She was curious, and a little disappointed that she wouldn't get to watch them slip around on the ice. It was such a rare sight around here.
When they got to the top she continued to lead them to a door that was inscribed with an eight sided snowflake, and she knocked on it.
"Come in!" called a voice that sounded like it belonged to an old man, and it was thickly Scottish.
Jackie pushed open the door and the Heads walked in. An old man with wild white hair and warm brown eyes was waiting for them. It was difficult to place his age, as he moved with the vigour of someone Jackie's age.
At the back of the room was a desk covered in various papers with pale blue files piled on top of it. There were also various chairs arranged in a circle, each one with a cushion on it and a rug lay on the floor. All of the furniture was made of solid ice, just like everything else.
"Welcome." said the man, presumably Alfred. "Jackie, yer good ta go now."
"See you later!" she said, smiling before shutting the door and disappearing to who knew where.
"Take a seat. Can't have ye standin' around like a bunch 'o lemons." Alfred invited and the Heads obliged, trying not to gasp at the cold of the ice. Alfred also took a seat, facing all of them, somewhat expectedly. Naturally the cold didn't seem to bother him.
"So, what to te Heads from the Order want with us?" He asked, his tone serious.
Jason was the first to respond, leaning forward in his chair. "Eye O'Donnell, are you aware of the events that happened involving the Guardians recently?"
"Aye, I've heard things." a knowing look appeared in Alfred's eyes. "Ah, Jack Frost has joined the Guardians, and so ye want us ta join ya."
"That sums it up." said Alexander, shrugging.
"Well, forgive me for being a bit wary. We historically don't have a good relation."
"It is true." admitted Jason, "but we're willing to look past it. So, will you and your kin join the Human Order of Guardians?"
Alfred leaned back on his chair. "I'll think about it."
Jason opened his mouth to protest, but Alfred shot him down. "It's ta best yer gonna get fer now. I'll get a message to ya when I've got an answer."
The four Heads looked at each and Jason sighed. "Alright, that's all we have to say. We'll await your answer."
"I'll see ye out." Alfred levered himself out of his seat, his cloak fluttering slightly as he walked to the door.
