The Curse of Ankhseram

(Third Person POV)

Within the domain, Jason activated an enchantment. A black magic circle appeared on the ground where Mavis lay. 

"I have to stabilize her vitals. I can tell, they're all over the place." Jason said as his left eye was black and white, "I then have to remove the mist, I assume is a combination of the curse and the eclipse darkness." 

Makarov, who had the rune barrier up around him, looked at him. 

"You mentioned this curse." Makarov said, "I don't know the full details of the First's situation, but are you referring to...." 

Jason nodded, "Yes." he said, "The Curse of Ankhseram, the Curse of Contradiction, and the curse of immortality." 

Makarov widened his eyes, "You mean..." He said

"Long story short, she and Zeref were afflicted with the same Curse." He said, "I don't know exactly how hers came to be but Zeref was cursed with immortality 400 years ago. That, too, is a long story." 

Makarov began to sweat, he was now hearing things he didn't think he'd be able to hear. Of all the rumors he's heard of Zeref, he never expected that. 

"I see..." He said

"Keep the barrier up, I'll have my waters restore your magic power if needed." Jason said, "I now need to focus, her vitals have stabilized.....now I need this mist off of her body...." 

"Sage God's High Enchantment:" 

Suddenly a black and nearly see-through barrier appeared around Mavis. Jason clutched his left arm as he grimaced. 

"This is a bit trickier for my first go..." He muttered to himself

He began to sweat a bit as he focused greatly on his magic power. What he was about to attempt was a very difficult and meticulous enchantment that Irene was reluctant to teach him. But because Jason did what she asked in return; 4 consecutive creampies without break, she felt like it was more than fair to teach him. 

"Separation." 

Suddenly, the black shadowy mist began to be extracted from Mavis and funneled towards the top of the barrier which resulted in a bubble. 

"Yes..." Jason said as he sweated, "Steady...."

Suddenly, Mavis's body began to convulse violently as the mist engulf her. The mist then spread all over the barrier that Jason used. 

"Shit!" Jason exclaimed 

He then swiped his hand and the bubble that contained a portion of the mist separated from the barrier. 

He then noticed that Mavis's body kept convulsing. 

"Hmm...." Jason said

"J-Jason!" Makarov exclaimed, "What's happening to the First's body!" 

"Quiet." Jason said

He stared at Mavis who was covered in the cocoon, the mist pulsating violently as her body also convulsed. It looked like he was in deep thought, trying to think of something. 

"Jason!" Makarov said

"Shut up." Jason said

He then raised his arm again as multiple magic circles appeared on the ground beneath Mavis. 

"Fuck it." Jason said, "I'll do it in one go. I'll deal with the curse later." 

Jason then plunged his arm through the barrier and the mist cocoon, clutching the dark mist. 

"J-Jason!" Makarov exclaimed

"I'll extract you without care." Jason said, "If I do it slowly, there'll be dire consequences." 

Jason then pulled his arm upwards, ripping the shadowy mist apart from Mavis. However, as he did this, the shadowy mist burst outwards and swirled within the barrier. 

Jason then swung his arm upwards and in an instant, the mist floated up into the air and merged with the bubble from before. 

They both then noticed that the mist was still connected to Mavis's body. 

Jason narrowed his eyes, "I take that back..." He said, "I still need.....fuck...." 

Makarov looked at him, "Jason?" 

"This is gonna take a minute, Makarov." Jason said, "Keep the barrier up." 

************************************

After almost 30 minutes of carefully extracting, Jason was able to completely remove the dark mist from Mavis's body. 

It had been gathered in a massive bubble the floated in the air above Jason. Makarov stood as he kept the rune barrier up, sweating in pure concentration. 

Jason crouched down as he looked at Mavis who was unconscious. 

"Man...." He panted, "That took a while....whoa..." 

"What is it?" Makarov asked

Jason looked at Mavis, "That's odd..." He said, "I swore Mavis's body looked younger than that." 

Makarov looked past Jason and widened his eyes in surprise.

"How is that possible?" He asked

Mavis, who lay unconscious, had the body of an adult, rather than a young girl as she normally was. She seemed bigger than she normally was, not taller since she was lying down, Jason couldn't tell. But he did notice she was a couple of inches longer, lying down. 

She was also naked, so Makarov was looking away as a way to respect her, due to the bigger "things". Jason, however, didn't care and kept looking at her new adult form. 

"How the fuck did that happen?" Jason asked, "Is this a result of the mixing of the curse and the eclipse?" 

'Eclipse darkness has resulted in crazy mutations...' Jason thought to himself, 'This could be another one...' 

Before they could say anything else, Mavis's body released a thick and black aura that hit Jason and the rune barrier. 

"J-Jason!!" Makarov said

"No matter what, keep that fucking barrier up, Makarov!!" Jason said as he braced himself within the black aura, "Do not let it down!!" 

"R-Right..." Makarov said as he clutched his arm

Jason looked at Mavis as his knees buckled, he was feeling a bit nauseous. He knew exactly what this was and he was surprised he wasn't down and out just yet. 

"Fuck..." Jason said, "The Curse, huh...."

"Great Devour." 

The massive black and thick aura was suddenly siphoned into his mouth as he ate the magic. This was only possible due to Jason being the Black God Slayer and being immune to any lethal effects of a black object he devours.

As the aura disappeared, Jason scowled, "That is disgusting...." He said, "My fucking stomach feels like it's corroding...." 

He then looked down at Mavis as he cracked his fingers. He thought of something extremely crazy, something he wasn't so sure it'll work. Extracting the eclipsed darkness was one thing, but what he was about to attempt was something else. 

"Here we go again." Jason said, 

"Hold out for a bit longer, will ya?" 

********************************

Jason collapsed to his knees as his left eye was black and white, his whole face covered in sweat. Behind him, Makarov was also on his knees as he could barely keep his eyes open. 

"J-Jason...." He managed

Jason looked up at a massive and pitch-black bubble that floated beneath the other bubble of eclipsed dark mist. This was densely black, completely pitch-black. 

"Fuck..." He said, "I have to...." 

He then stood up and waved his hands outwards. Suddenly, a massive mechanical cube appeared next to the pitch-black bubble and absorbed it in an instant. 

"Machine God's All-Cube." 

"Brace yourself, Makarov, the domain is collapsing...." Jason said as he got back to his knees

Suddenly, the domain collapsed and all three of them were ejected. They were back to the basement of the Fairy Tail guild hall. 

Makarov collapsed on the floor as he looked up at Jason who had Mavis's unconscious body in his arms. He was standing in front of where the lacrima had shattered. 

Jason looked at her, "Well, First..." He said, "That's one problem to deal with....." 

He gently placed her down on the floor and walked over to the massive mechanical cube that was letting out sparks and showing cracks. 

"It's impressive you were able to even contain it for this long." Jason said as he placed his hands on it, "But I got an idea of where to put that. Makarov, I'll be right back..." 

He clapped his hands as he released an immense amount of Curse power. 

"Cursed Domain: Bloodied Field of The Primordial Battle." 

In an instant, Jason and the cube were transported to the cursed domain. 

Jason landed on the ground and immediately threw up a black and gooey substance. The substance then caused the ground to corrupt as the blackness spread all over. 

He then straightened up and stomped the ground. 

"Earth God's Divide." 

The earth then split, causing a deep ravine. Jason then grabbed the cube and flung it down to the bottom of wherever the hole led to. 

He then waved his hand and the ground closed back again. After doing this, Jason collapsed on his knees, panting. 

"Man...." Jason said as he sweated, "I never thought that'll be possible.....extracting that curse...." 

"Thank you Irene."
