"As expected of my father to have hidden you within the realm of darkness, he only furthered my plan along," her father chuckled softly, his tone far from kind and all the darker than before, "What he failed in his creation, I've achieved in my own," she could feel his words against her ear, clawing at her inner eardrums, "To create a weapon such as the X-Blade, one needs a pure heart thrust through the contrasting purity. A purely dark heart thrown into the realm of light, or… a purely light heart…" he left off, trailing his words.

"-Thrown into the realm of darkness," Sarafina dropped her faltering gaze as the realization in her own words struck her, her heart skipping faster and faster, the pace of each beat growing in speed and growing in volume within her skull, pounding louder and louder, faster and faster.

"Precisely," she could hear the entertainment in his voice, his tone dripping with smug victory as he'd achieved what he'd waited so long for, "I'll admit, it was a tiring process, the effort needed to remain patient for as long as I have," Xander complained with an almost flippant air wafting around his words, "But then, the wait was worth it to have a heart as manipulated as it is now," a heart… her heart. Of pure light, thrust into the dark. The dark, darkness had tainted her.

She felt a surging rush through her veins, pulling taut at her muscles and mind, her eyes glazing over with a slightly darker tint. Sarafina could feel the heat reaching her skin, resignation to what she was, what she is, building and building within her chest, spreading from her core and warming her further. She could feel the burn of her powers scratching along her skin, clawing harshly.

"Stop what you're doing," her fathers' voice warned, Sara blinking behind her darkened eyes to see flames as dark as the realm she'd been thrown into, an aura of said dark flames wafting around her body, swaying with the uneven winds from where she'd been held by her fathers' force. She watched as he very subtly eased away from her, eyes sharply focused yet hiding something, something he refused to show upon seeing her this way.

Growling softly, her flames expanded, Xander shifting farther away by a handful of inches. Her earlier anger, she could still hear it screaming at her, telling her to let loose, to allow herself to let go. The voice was her own, but darker, heavier, almost comforting. She knew the voice. Avonia.

The warmth in the familiarity of the voice she recognized, she did let go, heat thrashing through her body and the moment she'd let go, she saw her face, the anger the creature had bursting from her in a scream, flames exploding and building to the sky in a single, large burst. Her voice echoed with her Heartless', the two mixing in radio.

"Avonia!" Sarafina and the Heartless yelled together the former able to feel her control halving, her creature taking her share within her body. Her head was thrust back, her voice resounding with the powerful creature, the sky faltering with shade and growing dark with her power still rocketing skyward.

"If you guys' value your sanity, we outta get out of the strike range!" Vanitas called out in warning, gradually backing up with most of the group following behind him. Thankfully, Ventus had been ahead of him in his warning, the blonde moving a tad faster while everyone helped the injured out of the way.

"What the hell's going on?!" the silverette exclaimed as he'd reluctantly caught up to the darker soul, Vanitas fully aware that he hadn't wanted to leave her, but judging from Cid being directly behind him with a grumpy-ass stare, he hadn't had a choice in the matter.

"She's summoned her Heartless!" he replied bluntly, getting straight to the point to avoid any unnecessary bush beating, "And it's not just any Heartless!" he added while taking a swift glance over his shoulder towards their friend. Vanitas felt lacklustre about seeing it, even wary of the creature she'd called on. He and Ven had been told that she was the last resort, and for her to be summoned…

Once they were far enough away, his pace had slowed to a halt, Vanitas stopping beside Ven and the rest of the group, the injured being set aside and promptly treated. He could barely believe it, his golden gaze focused solely on the darkness surrounding their friend, family. He hadn't expected to see that Heartless any time soon. It towered behind Sarafina, intimidating, more so than any of his Unversed or any Shadow and Heartless he'd ever seen. She put his creatures to shame in that regard. Completely black from the purity of Darkness, standing from Twenty to Thirty feet.

"Avonia," Ventus muttered softly beside him, the two watching as their friend expected coughed, her lips turning slightly red from the blood that left her, "The very first Heartless," she could handle it, but her body, with the state it was in, he wasn't so sure she could, the blood being a sign of that, "Not easily manipulated and only listens to one person," Vanitas let his gaze drift to the others, watching the shock build, the stun grow and concern skyrocket as she coughed up a bit more blood and began to lose consciousness, the Heartless taking control for her, "Sarafina has the Mother of Heartless within her,"

"He's in for it now," Vanitas comment curtly, arms crossing over his chest to hide his building worry. He didn't like where this seemed to be going, even less that Sara had lost consciousness and let her Heartless have the wheel, said Heartless looking anything but happy as its bright yellow eyes fell to the enemy, "She's pissed,"

"I can't watch this," Ven muttered, the darker soul dropping his gaze to him to see that his hands were covering his face before pressing himself against the darker souls' side as if to actually shield himself from watching what they both know was coming now that Avonia had her power and control. Vanitas would be surprised if the Graveyard would even survive this battle.
