I don't write much, let alone fanfiction, and it'll probably be painfully obvious why from this. That said, if I'm harrassed about it then I may actually finish it...
On this I assumed the machines beneath Ratayu are organic, they look like it anyway.

Chapter 1- Monsters in the Basement
Darkness, held together with yellow walls broken by bloody veins. There were voices outside that wall, and light as well, not much, perhaps, but it was there. She had seen it long ago, back when she could still hear the voice of the great one, before most of the lesser voices went dead and His followed a short eternity later.
This was after she had been dropped back into the darkness, the fetid, blood-warm, senseless darkness. After being given the first intoxicating taste of fresh air and seeing that there was something else outside the prison, something the voices had only hinted at. She still cried for that loss the only way she could; with screams that made the opaque yellow membrane shudder and the little voices, those that were left, cry with her.
There were almost no voices left now, even the clipped murmurs from outside the wall had ceased long ago. She stared at the wall, at the tiny things moving in it. There didn't used to be things in it; she would have noticed, and so would those other creatures with clipped voices. They hadn't liked the little things, they'd killed them every time they had begun to appear. She wasn't sure she liked them either, they crawled over her and made her itch and she could do nothing about it…
Could she?
She shifted her tail, remembering how it had felt when they had locked her back into the darkness; the hopelessness and fear. She had moved then, and after too, but not for a long time since. Her tail twitched, it felt heavy and awkward, but it moved. She tried her claws next and was amazed when they too twitched in response to her vague order.
She suddenly became aware of the many thousands of things crawling across her skin and over her eyes in a way she had never before. Almost against her will she shuddered massively and a coat of little things dropped off and skittered away. There were still more so she did it again, more controlled, the instinctive shake of a dog ridding water from its coat. The rotted wall tore from the stress of a ton of scale and muscle and she slid down the slick, rotting sphere onto a solid stone floor thick with mold and larva.
There was no light; it was nothing like she remembered. Tattered bits of flesh thick with crawling things hung everywhere, falling with wet sounding plops at intervals to add to the heaving mass on the floor. Rising despite her weakness out of sheer revulsion, she slithered and slid over the pale, writhing bodies to a place that looked cleaner.
A path of rotting sludge less deep then the surrounding stuff led to somewhere opposite the direction she had faced that time long ago. After resting her shaking muscles for awhile she moved on, feeling cooler air in the direction the path led, eventually reaching a small opening that blazed with light. After blinking for several minutes, unable to tear her watering eyes from the sight, she began to notice details in the stone the silver light shone on. Moving closer, she saw deep, whirling designs on the dark marble that led her eyes upward towards the opening itself, though she had another fit of blinking before she could look directly at the silver-ish white orb glowing above.
Moon… She felt she had always known what it was from the dream images of the lesser voices, but the reality of the softly blazing… thing… It defied all description. She didn't know how long she stared at it, but she noticed when it began to disappear behind the walls of the tunnel!
Feeling as though she'd just been shocked awake, she flung herself at the tiny opening and tried to squeeze her emaciated, though still considerable bulk through it. Failing that, she brought her oversized claws into play and ripped at the hard stone, desperate not to be left in that darkness again. Heedless of the pain of her breaking claws and the rocks and dust falling into her almost blind eyes, she dug up through the rock to catch another glimpse of the moon. She dragged herself upward until she could push herself out of the widened hole, where she froze.
Colors, not bloody yellow or red, not rotting gray-green, not the coppery brown of dry blood. As far as she could see the ground was a bright, clean green with blurry gray and dark blue in the distance. A sweet smell came from that grass, and a vaguely salty scent tainted the air. Turning, she saw stones rising high above her head and heard the distant mutter of human voices from behind that wall. A quick shudder and she turned back northeast, towards the blue-ness in the distance. She was free, but they would not like that, she was sure.
Although overwhelmed by the senses overload, one thing pushed to the forefront of her mind; a gnawing ache in her belly, getting stronger as she scented the pristine air. Hunger…

That was the easy part, writing humans is much more difficult...
