Hey thanks to everyone who has read and reviewed this so far :) We're starting to get into the meat of the story so I hope you enjoy where it's heading. I don't know how true to J.K's writing my explanation of how the case works is, but it's the best way I could come up with. Let me know what you think :)

Newt strode across the plains of his case with purpose Tina by his side, a comfortable silence spread between them as they walked, their hands loosely interlinked. Newt was glad for the quiet, his mind swirling as he tried to establish what he had to do to hold his latest guest, and what he was capable of given his weakened state. Sensing his inner turmoil, Tina gave his hand a squeeze, and offered him a comforting smile when he glanced up at her. Behind them Queenie and Jacob were bustling away in the hut, preparing for feeding time, as despite the impending mission there were still duties that had to be attended to, and no one wanted a hungry Erumpent on their hands.

The pair left the plain, entering a dense wooded area, Newt led the way confidently, using a path only known to himself. Tina could feel a still and powerful magic growing as they drew closer to their destination. All of a sudden they emerged out into a glade, thickly carpeted in meadow flowers, and Tina found herself having to shield her eyes as they stepped out of the dappled wood into the full spring sun. In the center of the clearing was a flat, crumbling slab of granite, which had a veneer of moss and lichen that typically took centuries to accumulate. It was from here that the intangible sense of power emanated, lapping over them in waves. Newt stopped just short of the rock, taking a second to appreciate his surroundings, tilting his head towards the warming sun he breathed deep, the air was thick with the scent of blossom and loamy earth.

"What is this place?" Tina whispered, almost afraid to break the stillness that surrounded them.

"This is the centre of the case's magic, where we laid down the first spellwork," he explained as he rubbed his thumb across her knuckles, a look of pure contentment on his face, "From here everything else grew and is regulated, and whenever I have to make a big adjustment to the structure it has to be done from this spot,"

"It's incredible, I've never really felt anything like this, the magic here is almost visceral.. I can't really explain it," Tina breathed, in awe of her strange English wizard, "you must be incredibly gifted to create something like this."

Newt ducked his head, blushing at her compliment,

"Well I wouldn't say that, I had help to produce the spellwork, and it took a while..but I am proud of what we managed to achieve here," he responded.

"As you should be..just amazing...so what happens now?" she enquired.

"Okay, so I have to tap into the basal magic that is centred here, then I'm going to make a new, heavily protected area for the Mishipeshu, I don't really know how powerful it is so its better to be safe than sorry," he explained with a slight frown, "it might take me a while as I'm not back to full strength..I may need your assistance..but hopefully not."

Tina leaned into him, her arms encircling his slender but strong waist and she stretched up to give him a kiss on the cheek.

"That's why I'm here, anything you need just ask...I really don't want you to get to that point of magical exhaustion again," she said, her deep brown eyes shimmering with worry.

"Me neither, I don't want to leave you alone to tackle the Mishipeshu,"

Newt took her face in his calloused hand, gently stroking his thumbs across her cheekbones, before drawing her into an impassioned embrace. Tina felt her breath catch as she responded in kind to the deep, desperate kiss, she could almost taste his fear and determination.

"I'm so glad I found you," Newt sighed when they broke apart, both slightly giddy from the overwhelming desire between them.

"So am I," she said softly, capturing his mouth in a more tender moment than the last. When they separated for a second time Newt was wearing a determined mask.

"Okay I better get to this.."

"Please let me know if you need help,"

Newt nodded and gave her a final squeeze, and climbed up onto the rock, as he took a seat and closed his eyes an eerie sense of calm spread over the meadow.

He found his centre and connected to the spiralling core of magic almost immediately, after so many years of living in it, the case had almost become an extension of his own consciousness. Taking in deep, measured breaths he focused on what he wanted to create, scanning the mesocosm for a suitable location. He decided on the area which had previously contained the Obscurus, as it already had a fair amount of warding in place, so it wouldn't require starting completely from scratch. In his mind's eye he watched as the arctic wasteland began to thaw, jagged cracks fulgurating across the surface of the sheet ice. He dug his hands into the thick moss covering the slab in an attempt to anchor himself, the effort was draining him faster than he had expected.

Tina watched on in worry as Newt's breathing began to quicken, after ten minutes he was panting with the strain, beads of sweat rolling down his pale face. She moved nearer to the rock, wanting to be as close to hand as possible, but didn't speak for fear of breaking his concentration.

Finally all the ice had melted, leaving behind a choppy lake with a rocky outcrop stretching out into its centre. Satisfied that this would provide a suitable habitat, Newt turned his attention with considerable effort to the wardings surrounding the area. Piece by piece he began to construct invisible barriers that he could only hope would be strong enough to hold the creature, starting from deep below the frigid waters he built them upwards in a high dome. By the time he was half way through, Newt was struggling to hold it together, his breath now coming out in wheezing huffs, gripping the rock so hard he was white knuckled.

He wasn't going to make it.

Tina couldn't take it, Newt was totally devoid of colour, shaking from deep within his core, she couldn't stand by anymore watching him suffer like this. Just as she made her mind up to try and bring him out of the trance, his pain-filled green eyes snapped open.

"Help me," came the barely audible plea.
