Desperate... Reeling... Gasping... Taken over the edge, into...
She hobbled and put her hands on the wall, gripping at the cold stone that surrounded her, lit by only an unhealthy pale green glow. She could see the faces of the damned howling within the acrid 'steam' that rose from the depths of the cave she was in... See the steam curl, and twist unnaturally within the air's currents, until it hit the tag on her middle, marked with a number of cruel symbols...
It was Halloween soon, and the grim ghost had decided that of all things, she would be a real witch this Halloween. When the month of harvest began, all the way back on the first day, she had travelled from her lonely little haunted hut and through the swamps to the lonely cave she now inhabited. Deep below, in a perfectly circular chamber so far away from the sunlight that the only glint of hope was a hole far above that shined a spotlight of it on her at noon, as if to weaken her ghostly self further...
She had stood in this place, ran a finger over the scoured markings in the floor, and then stood in their center. She spread her arms and loudly expounded about how much she'd done for the forces of the dead; the cruelty and the horror... The sacrifices... Her thirst for fear had spilled into a thirst for blood, and now she demanded the dark things below the underworld themselves come and grant her a boon... A hateful boon that would allow her to summon forth the spirits and haunt the world at her leisure...
But what she did not know is that as vile as she was, the things below were far more eager to have a portal, than a necromancer...
She had thought nothing when the tag appeared attached to her belly... A simple spelltag that 'burned' into existence, through reality's curtain. She had felt the effects immediately however; the souls of the dead siphoned into her... They needed a way to walk among the living... A path. A portal.
A vessel for their terrene selves...
She had waddled back and forth in vague worry. The cave was pitch dark, save for the brief moments when the sun illumined it. When she had become so nervous that she checked the path back up and out of the cave, it was blocked off by a mocking barrier of pallid, spectral hands... As if to push her back into the chamber...
She had gotten what she asked for, hadn't she?
She swelled and swelled and swelled, and within a day, she found herself so pregnant that she couldn't even close her thighs. She scraped the walls and cried out, but grit her fangs and bore it up until the moment it became clear; she wasn't allowed to give birth. There had been no contractions. Just swelling...
Stretching...

Aching...
By the time just before the sunrise of the second day, she sat in a corner of the room sobbing and holding her middle. Was it punishment, or had the evil things simply betrayed her? She could not think straight... She watched her belly stretch and rip her dress... She watched marks form, like cracks across the surface of an egg... She howled out in agony as her stomach finally gave, a small split at the top, moments before she burst and spilled terrible black offal onto the summoning symbols below. With tears in her eyes she fell back, ready to embrace death... Her punishment... But as her little ones burst forth and fluttered up, and up, and out of the hole above...
She laid there, split wide, and eager to die so the agony could be undone. But she watched the symbols glow... And another strip was placed across her belly... Like a staple or a stitching across the vast scar that she now had... Her flesh messily stitched together, 'fixed' by the bandaid of a second tag... And then? Both lit up again...

Ahhh the month was back breaking. She swelled up over the course of every day, and just before dawn would burst again and release her babies. But no matter how much she begged, another tag would appear and stitch her up again before pushing her forward headfirst into the agony of her unnatural undead maternity...
She clawed the walls... She tried to destroy the symbols, to no avail... She beat the barrier of hands that kept her back... She screamed to the heavens... But she had blasphemed and abandoned them long ago... She was fully in the clutches of those she had chosen loyalty to; the dead. The dead who clawed their way out of her tummy again and again and again, until...
The 31st. Hallow's Eve itself. She could almost hear the ringing of a grandfather clock in her head to signal it... But that might have just been the madness. Frayed and with a belly 'stitched' up by tags, she didn't know what to expect on this night... The night where she was to 'fulfill' her contract... But she knew, as she sat there in a corner with a swelling belly and tearstained eyes and a messy head of hair, that she would not be allowed to leave without the grand finale... 
The day of Halloween felt all too short... Her belly stretched and strained and bulged its unnatural stitching, stained by the tarry blood she leaked if something kicked too hard or moved too fast, until night fell...
She laid on her side in the center of the ritual circle. She sobbed gently and begged once more for mercy, for forgiveness! For all the evil she did...
But no one was there to listen to her... So far below, in the shadows of an ancient graveyard...
As she felt her belly swelling and swelling once more, she screamed and howled. The moon, full and bright, slowly moved until it was aligned with the hole above, casting a fel image of the horrid scene... Her on her back, arched and clawing the dirt, trying her damndest to push... She couldn't care less about broken hips or damage anymore... But that just made it all the worst when the pain redoubled, and so did her belly...
She burst once more, around her biggest children yet... Healthy, happy things that she could never have birthed anyway for their size. Instead, they rushed from her belly the moment she peeled open...
Laid there, split and unfolded like a flower, she twitched and gasped a few times, blood dribbling down the side of her face. She stared up at the moon and... She could swear, far above, it looked like a mocking Jack O Lantern...
Her huge eyes went dim. Her children were gone. Her screams unheard. And the place would forever house her tomb... And her womb. Her earthly body of ghostflesh would remain there, while her spirit was slowly tugged from her body by the ghostly hands... And then dragged down...
Her howl of horror was unheard. It echoed a moment, then faded away...
Her body was finally allowed to collapse and disappear, leaving only the hat... And a fluttering cloud of ominous tags...
