'What. The. Hell.'

'Jack... wait no-!'

The doors burst open and the Guardian strode in with fury in his icy eyes.

'I leave you people for a few hours- a few HOURS! And you mean to tell me she's GONE?!' he screamed through gritted teeth, waving his wooden staff in Hellion's general direction.

The telekinetic batted it away.

'It's not my fault,' he began.

'You expect me to believe that? You were the only other person there, how could you be that incompetent?!'

'How do you even know that?' Hellion sighed in annoyance, barely masking his irritated expression.

'The little kid told me,' Jack replied, still brimming with anger.

Hellion shot Trance a furious glare. The small girl flashed an apologetic grin and hid in the shadows of the room.

'Well... whatever you heard- wait... why are you even here?' Hellion asked the Guardian in suspicion.

'A portal opened... why would I not be here?' Jack replied snappily.

'We open portals all the time and you've never showed up!' Hellion shot back, telekinetically batting Jack's staff against the wall.

The Guardian bristled.

'Well this portal was massive and it was just after a WAR what did you think we'd do?' Jack snapped.

Hellion growled. 'I don't know. Maybe you'd sit back on your lazy asses like you always did.'

'We never-,' Jack began, reaching for his staff.

'Spare me, kid. We've saved the world waay more times than you have,' Hellion spat venomously.

Jack made a sound at the back of his throat that sounded like he was going to explode.

'Well if that's the case, why couldn't you save her?!' he gritted out, brandishing his newly acquired staff in anger.

Hellion paused. 'You little shit,' he said, before reaching out with both arms to tackle the wiry kid to the ground.

'STOP!' someone shouted, and Hellion felt himself being lifted away from the tiny Guardian who was now squashed into the carpet.

Trance's astral form held him aloft in the air long enough for them to exchange fleeting glares, and then he was on the floor.

'Ungh,' he grunted.

'Bumpy landing,' Trance warned belatedly, from across the room.

'Get back here,' Jack was groaning. 'Coward.'

Trance's astral figure kicked him in his side.

'Get over your petty ego, Frosty,' real Trance snapped. 'You are pretty useless.'

Hellion snorted happily.

'You too, Hellion. I can't believe you let Els be kidnapped... princess-napped… whatever,' the petite pixie-like mutant shrieked in annoyance. 'Now stop acting like brats and DO SOMETHING. YOU TWO ARE SUPPOSED TO BE POWERFUL, GODDAMMIT!'

'Ouch,' Surge chuckled, appearing behind Trance from the doorway.

'Oh,' Trance mumbled. 'Didn't see you there, Surge.'

'Chill, girl,' the blue haired mutant replied, laughing it off.

Her strained laughter faltered as she caught sight of the Guardian sprawled on the floor.

'What's he doing here?' she seethed, crouching into an offensive battle-stance.

Trance sighed. 'Am I the only one who doesn't hate him?' she asked herself.

Hellion nodded with a scowl.

'Listen,' Jack said softly, raising his arms in an appeal. 'I'm here to help.'

'Who says we need your help?' Surge replied snappily.

'Calm down!' Trance sighed heavily. 'You're destroying your own auras.'

Everyone fell into a silence.

'Our... what?' Jack ventured after a while.

'Wow. Talking like Blindfold really shuts people up,' Trance noted brightly.

'Ugh, that stupid blind seer,' Surge growled to herself.

'You really hate her huh,' Hellion observed quietly.

'Surge hates everybody,' Trance supplied cheekily.

The blue haired mutant looked like she was about to object but something stopped her.

'You guys,' she said loudly. 'Focus. Operation: Save-The-Ice-Queen must start now!'

Hellion grew forlorn.

'Oh spare us your pouting, Green Bean, and do some plan-making,' Trance squealed, racing for the desk that sat in a corner of the room.

'Green Bean?' Hellion asked as he followed her.

Jack walked behind him, casting occasional glances in Surge's way as if he were trying to figure her out.

'Yeah, it's a nickname,' Trance replied as she whipped out a pad of paper and a pen. 'Green for you know... your powers.'

'And "bean"?'

A pause. 'It rhymes.'

Hellion sighed.

'What are we going to do about Elsa?' Jack asked sullenly.

'Why don't you think something up if you're so clever?' Surge snapped at him with a scowl.

Jack looked confused. 'I never said I was cleverer than any of you,' he protested weakly.

'Oh boohoo,' Surge mumbled mockingly.

Jack was torn between wanting to run away and falling to his knees while ripping his hair out. This girl made him want to scream... why was she so cruel? Women in this century wore him out. And not in the good way.

Was there even a good way?

Trance shot the Guardian a pitied look. 'Chill, Sparks,' she mumbled. 'Give Frosty a break.'

'Nicknames for all of us,' Hellion observed grimly. 'Yay.'

'So here's the plan,' Trance interjected in a louder tone of voice.

Jack jumped, startled. 'Where- what is it?'

The young mutant gestured at the blank pad of paper.

'It's waiting for you pig brains to quit fighting and start thinking,' she said.

They sighed and grudgingly began to plot in their minds.

'So she went in a portal?' Jack asked tentatively, breaking the growing silence.

'I thought you knew that,' Hellion retorted, raising a brow.

'Can it, Green,' Trance snapped.

'Yeah it was a portal,' the telekinetic answered sullenly.

Jack sat back to think.

'Can you guys open portals?' Trance asked after a while.

'Yes,' Jack answered.

Trance nodded slowly. She sat back too.

'Well why don't you open up a portal and save Elsa already?!' Surge interrupted angrily.

Jack raised his brows. 'I don't know who took her or what realm they went to.'

Trance sighed. 'Stop trying to be smart Sparks, you're killing the vibe.'

Surge snorted. She didn't like this.

At all.

A great silence ensued.

'How do you open portals?' Hellion asked at last.

Jack started. He didn't realize he was being spoken to.

'Um... I... uh we use magic,' he supplied.

'Well duh, tell us something we don't know,' Surge muttered darkly.

'We use crystals from up North where Nick lives,' Jack amended hastily.

'Nick?' Trance questioned.

'You call him Santa. Anyway, the crystals possess enough magic to tear a gap between the realms. It sounds horrid, but it's safe. It wouldn't be if I use my own magic. That's why I carry this around wherever I go,' Jack continued, pulling a rope necklace out of his shirt. 'I use them to come down here and go back. I used one today.

The fraying necklace was made casually out of a dark fine rope, and was tied carelessly at the end. Towards the middle, there hung three gleaming crystals, jagged and sharp edged, reflecting the warm colors of the room. They all stared at it warily. 'So we smash one of those and open a giant portal?' Surge guessed.

Jack nodded. 'Sort of, yeah. But we have to know where we're going. If not we could end up in Limbo.'

The X-Men froze involuntarily. Just the mention of that realm left them uneasy.

Jack didn't understand.

He ploughed on awkwardly, trying his best to ignore the sudden uncomfortableness.

'We could all go I guess- one crystal is enough to let all the Guardians through.'

'What does that mean snow boy?' Surge demanded. 'I thought we were all going anyway- no questions asked.'

'It's "Frosty"... use the right name,' Trance sighed.

'No, one crystal portal can only support five people-no more,' Jack answered warily.

'So we can all go,' Surge rolled her eyes.

'Yes...that's what I said,' Jack groaned in confusion.

Hellion's palm met his forehead with a slap. 'We're never going to work this out.'

'Don't worry, Green. We will,' Trance whispered soothingly. 'I know a thing or two about portals.'

All three of the others shot her a questioning glare.

'Oh come on,' she moaned. 'Which one of you were best friends with Pixie the portal maker? Me... Yes that's right.'
Surge and Hellion flinched at the name.

'Go on,' Jack urged.

'Well, truth be told Pixie didn't really make portals per se,' Trance mumbled to herself. 'But she did teleport- which is kinda the same thing. Sparks, I can see you trying to argue and I'm telling you now- don't. Anyway, portals are generally magical. Unless you're Hank and you scientifically rip a hole through the fabric of space and time.'

'Get to the point,' Surge sighed.

'I'm going there!' the brunette snapped. 'Ugh, you're making me cranky too. My aura is soo getting killed.'

'You've been hanging around Blindfold for too long,' Hellion observed.

'Who's Blindfold?' Jack asked, curiously.

Surge frowned at him. 'She has no eyes,' she deadpanned.

Jack recoiled in revulsion.

'Would you guys just listen?' Trance moaned. 'Magical portals take up quite a lot of power- not too much, but enough to leave a trace. Think of it like a magical carbon footprint. This portal was massive, so the footprint it left must be huge.'

'Can we trace this footprint?' Hellion asked eagerly.

Trance grinned. 'You're catching on, Greenie. We can trace it to where the portal was opened- not the exact location but somewhere close by.'

'And how do we do that?' Surge asked skeptically.

'I can do it,' Jack offered suddenly.

'Excuse me what?' Surge asked, whipping her head around to glare at him. 'Who asked you?'

Jack ignored her. 'I can sense the magical residue. That is what you were talking about right- a magical residue? I can sense it just like I sensed the portal when it was in use.'

Trance clapped her hands in glee. 'Amazing! I thought we would have to steal Hank's tech for that bit. This plan is much better.'

'And then what?' Surge asked sullenly. 'Do I get to do anything?'

'Not yet,' Trance answered, still cheerful. 'Jack you said you can open portals with your own magic, yeah?'

'Yes, but its dangerous,' the Guardian answered, alarmed. 'That's why I use-,'

'The crystals, yeah, yeah,' Trance waved his objections away. 'I'm not asking you to open one- I just wanted to know if you could.'

'Well what's the point of that if I'm never going to open one anyway?' Jack asked suspiciously, his blue eyes narrowed.

Trance beamed. 'You're going to have to reverse one that's why.'

'Reverse a portal?' he asked in confusion.

'That's ridiculous,' Surge snorted.

'Well I don't hear anyone else's genius plans!' Trance snapped. 'And it was just a suggestion.'

'Probably the only suggestion we'll ever get,' Hellion said, sighing heavily. 'Surge we're not going to be able to form a purely intricate plan in time.'

The blue haired mutant scowled.

'How do I reverse it?' Jack asked tentatively.

Trance glanced over to him. 'Let's go to the site and find the portal first. Then I'll tell you what to do.'

They found the elm in front of which the portal had opened.

'I thought the portal was in the sky?' Hellion asked in confusion.

'That was probably the portal's trajectory through the realms. It entered our realm through up there,' Jack explained waving an arm at the dark night sky. 'And it opened down here.'

'You sure it's here?' Trance asked from beside the tree.

'It has a residue so foreign it can't be missed,' Jack answered with a self satisfied grin.

Surge wanted to slap it off his face, but something held her back. Curiously she asked; 'What kind of residue does it have?'

Jack started. Was she talking to him?

'Like can you hear it? Or smell it? Or can you see it?' Surge was saying.

He stared at her for a while longer before answering.

'There's a taste in the air. Usually it feels crisp and slightly burnt. Maybe even minty if North opens his portals. Sandy's portals are slightly dusty and have an overwhelming taste of mothballs. Tooth's portals are very bad- she sucks at it. And they taste too sweet.'

'What about the kangaroo?' Surge asked, berating herself inwardly for ever starting a conversation with him.

But she wanted to know.

About these portals. About what Megan knew. Maybe then she could understand her? Was her knowledge too much? Did she know dark things?

Jack pulled her from her reverie.

'Bunnymund doesn't do portals,' he said with a nostalgic wry smile.

'Over here, you two,' Trance called irritably. 'Quit slacking off!'

Jack shook his head with a grin and walked over to the tree. 'So now I reverse it?'

'Yup. Basically, you've just gotta- well… I dunno.'

'Trance,' Hellion began.

'I'm sorry; I'm not a portal genius! But I got us this far didn't I?' Trance pouted.

'Well what do I do?' Jack asked in worry.

'I thought you would know that!' Trance replied woefully.

'Hold it,' Surge called. 'Calm your faces. Maybe you've just got to reverse it.'

'Well that helps, keep going,' Jack replied sarcastically, flipping his stark white hair.

Surge scowled deeply. 'Maybe you've just got to change the direction back. Like when you make a portal you try thinking of where you're going. So reverse it and think of where he came from.'

'Who?'

'The dude who took Elsa.'

'Ah.'

'That actually makes sense, Sparks,' Trance grinned.

Surge acknowledged this with a sharp nod.

'So wait,' Jack called. 'I'll have to use the residue.'

'Why?' Trance asked with a frown.

'I can't trace him back if I make my own portal, independently to his.'

'So make it.'

'Well, there's not enough magic residue to create a big portal.'

'Why, Universe?' Hellion asked with a groan. 'Have we enough obstacles already?'

'Maybe you can mix in a bit of your own magic,' Surge offered.

'I'll try,' Jack sighed.

He leaned towards the spot he'd said the portal had been and began frowning resiliently at it. Sparks flew and the area became fogged over with mist.

'Well, we've got the right spot, at least,' Trance mumbled.

Jack grunted in reply.

He thrust his hands forward carefully into the milky mist swirling around before him and began stirring it around. His fingers combed through the white tendrils and batted them away. The sparks grew into flashes of light and magic. The wind howled a little louder. The mist turned darker, and the flashes of light glowed green.

The mutants watched with bated breath.

The sparks receded and the light stopped flashing and instead expanded into a constant bluish glow. The mist faded out to the confines of the circular portal area, but nothing had opened.

Through the ring of mist and light they could just see the rest of the elm and the forest.

The wind screamed past them. Above their heads the clouds began to stir. Jack stiffened slightly and when he spoke, his voice sounded very strained and hollow.

'I got it,' he said softly. 'I found the way back.'

He opened his eyes and they glowed a brilliant white. He frowned slightly and his lips twisted into a grim line.

He spread his hands, leaving a frosty trail behind, and the air within the mist circle snapped with a screaming sound. Before the others could even shield their ears, the fabric concealing their own realm from every other tore apart, laving a giant gaping void. The mist swirled ominously around the tear in time and space, circling it protectively.

'Hurry,' Jack mumbled tersely. 'I can't hold it open any longer.'

The mutants stirred anxiously.

'Me first,' Hellion decided, as he headed for the obsidian void.

Something pushed past him and he barely registered it as Trance catapulted herself into the portal headfirst. 'You snooze, you lose!' she yelled as she went, whisked away by the magic.

'Trance no!' Hellion cried, leaping into it himself.

Surge sighed. 'There better not be any giant caterpillars there,' she mumbled, before stepping in reluctantly.

Jack sighed. This was going to be interesting.

He held the portal open for a heart beat longer, and then threw himself in after them.

The darkness that greeted them was so densely blinding, they stood disoriented for five whole minutes.

'I can't believe it,' Trance muttered. 'This must be what Blindfold sees everyday.'

'I can't believe it,' Surge snapped irritably. 'We're lost.

'No,' Jack protested. 'This is where the portal came from. Sort of.'

'What does that mean, Frosty?' Hellion asked carefully.

'This may not be exactly where the portal was made, Green,' Jack replied sullenly. 'But this definitely is the realm he came from.'

'Who?'

'The guy who stole Elsa- duh!' Jack snapped loudly.

'Quit yelling,' Surge complained.

'Yeah what was that about?' Hellion groaned, searching blindly in the darkness for someone to slap.

'Well someone was being irritating,' Jack replied stubbornly.

'We didn't even say anything,' Trance said.

'You didn't?' Jack asked quietly.

'You're hearing things.'

'Yeah, maybe I am,' he mumbled.

'Now what are you saying?'

'Surge, was that you?'

'Trance?'

'Yeah, you told me I was hearing things.'

'No, I think she told me that.'

'Shut up both of you.'

'I didn't say anything!'

'Stop yelling, Sparks!'

'You stop!'

'You people are fun!'

The mutants and Guardian froze.

'Uhm…,' Hellion ventured.

Suddenly, the blackness lifted like a curtain and a strange filtered light illuminated their surroundings.

They were in a garden, a small backyard of sorts. It resembled the Bennett's garden to some extent, but most of the plants were overgrown and creepy. It was dawn in this new realm, and warm rays of sunlight were filtering through one end of the strange place they were in. It seemed to be a cave. Light streamed dully from the mouth of the cave but failed to illuminate its furthest reaches. The cave ceiling was raised high above them and disappeared deep into the shadows. Before them, sitting in the middle of the cave floor, was a pink house.

On the doorstep was a girl.

She stood there watching them with a lopsided grin.

No- she floated there.

Her matt red boots hovered inches off the ground, followed by her tattered, casual jeans and her red plaid shirt. Surge glared at her hair in envy. Thick raven locks fluttered in the wind, dangling down to her waist and completely engulfing her entire frame, like a cape.

It was beautiful and scary.

Just like her eyes.

They looked lizard like and took up most of her face. They were far too big for her pale ghost complexion. And they seemed to shift.

Every blink.

Shifted.

They changed from black to blue to mauve to green- every time she blinked. They seemed to entrance anyone who looked into them.

'Well you guys must be lost,' she said after a while, in a lilting voice.

'Who said so?' Surge challenged.

'You're in my backyard,' the girl deadpanned.

'Oh.'

'We didn't mean any harm,' Hellion offered, tentatively.

'Yeah I figured,' the girl replied with a small smile. 'You guys are so hopelessly unarmed.

'That's what you think,' Surge snapped.

'Sparks,' Trance warned softly.

The girl looked terrifyingly glad Surge had challenged her.

'Can anything you've got match this?' the girl asked, her eyes dancing in glee.

One minute she was standi- hovering there, and the next she was exploding.

Her body ripped open from inside out and she began transforming into a massive lumpy creature. The shadows bent towards her as she grew and grew, even taller than her petite house. The creature that she'd become vaguely resembled a giant bat. Its matted fur was caked in blood and its wings unfolded above its head- paper thin and shredded in places. It turned its monstrous head to face them and Trance nearly fainted away.

The bat creature had no eyes, just gaping voids for where it had sockets. Its tiny nose twitched in their direction and a small pink tongue dashed out from between its lip-less mouth. It screeched and lunged for them, relishing in their screams.

And then it was shrinking and receding back into the porch where it had grown from.

'I thought not,' the girl said smilingly, as she finished transforming back.

'What the heck was that?!' Jack cried, helping Trance to her feet.

'Ah, just my true form, that's all,' the girl said cheekily, dismissing their horror with a wave.

'Your true form?!' Hellion groaned.

'Who are you?' Surge asked in a shaky voice, cursing herself for not electrocuting that beast.

'I'm Marceline, the Vampire Queen,' the girl replied. 'Don't worry, I won't eat you.'

Hellion had been thinking about this quest, and what he would have to face. He knew realms were dangerous, especially ones he'd never heard of. But nothing he'd thought of would have prepared him for this.

They were all in the Vampire's house, seated uncomfortable on her stone hard sofa, while Marceline floated around listening to their tale. Apparently Vampires didn't need to sit. Ever.

She'd been friendly so far, showing only a fleeting sadistic pleasure in their horror.

She didn't answer any of the questions they'd had concerning her and her… cannibalistic tendencies.

Wait- was it even cannibalism if she wasn't human?

Hellion didn't know.

He needed Elsa. He needed her beside him, on this stupid rock sofa. If she were here, she would've frozen that bat-creature no doubt. If she were here she would've attempted to hover as well, instead of sitting on this goddamn couch. If she were here-

Hellion paused.

He could feel himself growing sadder. He couldn't afford to. His game always got thrown off when he mourned.

He couldn't help wondering how Elsa was though.

She must be so scared, he wondered.

As strong as she was, he knew she had a weak spot.

Loneliness.

Abandonment.

She hated being lost. And confused.

Right now she was probably all those things and he could only blame himself.

He sighed. This day was exhausting him. This land was stranger than he'd expected. According to the Vampire, it was going to be hard for them if they couldn't handle her weird transformation.

'Ooo is full of creeptastic things,' she chortled.

'Ooo?' Jack asked, raising a brow.

'that's where you are- the Land of Ooo,' Marceline said, grinning. 'Looks a mess… but it gets messier.'

'Sounds like a dumb place to me,' Surge complained, shifting on the couch uneasily.

'If you say so,' the Vampire acquiesced, shielding a Cheshire-cat-grin from their view.

'We're looking for a friend,' Trance offered meekly, still recovering from her near cardiac arrest.

'You won't find any here,' Marceline answered.

'No, you don't get it. Our friend was abducted and brought here,' Jack explained, watching the Vampire carefully.

Her eyes shifted too much for his liking. He felt the constant need to be on guard.

He also wanted to sleep, this couch was so nice.

'Abducted you say?' Marceline asked, perking up in interest. 'Ooh, by who?'

'We don't know,' Hellion replied shortly.

He didn't trust this…..thing.

'And now you all are lost and helpless?' Marceline continued, ignoring Hellion's suspicious frowns and Surge's indignant protests.

'Yeah, mostly,' Jack admitted.

'Well you're in luck,' Marceline announced. 'I can help you.'

'Just like that?' Trance asked with a frown.

'We don't need your help,' Surge snapped at the same time.

'Of course you do, don't be silly,' Marceline laughed. 'And no, there's a price to my assistance.'

'How much?' Hellion fired back.

'Two things,' she answered with a smug smile.

'Care to articulate?' Jack asked slowly.

'Nope. It's too long,' Marceline sighed wearily. 'Plus, it'll take more time and we could be on our way to saving your friend.

Hellion drew a deep breath.

'Fine,' he snapped. 'Just two things.'

Marceline nodded with a grim expression. 'Just two.'

'Fine,' Hellion repeated, much to Surge's chagrin.

'Wait, you must swear on it,' the Vampire added, with a sheepish smile. 'Forgot that bit. Promises are vital here in Ooo.'

Hellion rolled his eyes and stood up from the sofa. 'Fine, fine, we promise. Happy?'

Marceline grinned. 'Very.'

'So now what?' Surge exclaimed. 'You said you'd help us?'

'Uhm, I'm actually going to find you the help you need.'

'What?'

'Well there's really only two people who're totally cut out for this job.'

'And who're they?'

Marceline's face soured. 'The stupid boy and his dog.'

'Uh, and how do you know they'll help us?'

'Oh, they'll help, alright. They always help. They're stupid like that.'
