Witnessing Jonathan's transformation into a humanoid black dragon, Kain scoffed. "Show-off," he muttered, then began his own transformation. "Vampyrus Morphum!" A pair of black leathery wings sprouted out of his back, while his robe morphed into scarlet armor; his hair became longer and wilder, and ancient red glyphs appeared all over his skin.
"My turn," said Nyxia. Her pale, smooth skin began to glow with power, as a pair of translucent, shadowy, ethereal wings of Darkness appeared behind her back, flapping gently and sending black sparks into the air. But the transformation did not stop there. Closing her eyes, Nyxia concentrated, letting out a quiet hiss; streaks of red began to appear in her black and lavender shadow aura. Her eyes opened abruptly, and they were no longer the usual color of midnight black; instead they were red as blood, with slit-like pupils, identical to those of Jonathan and Kain. She wrapped her shadowy, fairy-like wings, now streaked with red, around herself, and those wings began to condense into something else. Within moments Nyxia's body was covered by concentrated dark energy; her assassin's black leather garment was transformed into lightweight black armor, decorated with hints of red and lavender. Then, a pair of black batlike wings, real wings made of matter instead of energy, burst out of Nyxia's back, along with a slender, barbed tail; her black hair was now a luscious shade of deep, dark red, and two small black horns had grown on top of her head. Instead of a Black Nymph, Nyxia now resembled a female Demon, somewhere along the line of a Succubus. She smiled seductively, showing off her fangs.
Kain stared at Nyxia, his eyes almost glued on her face and body. He had never really gotten over his infatuation with Nyxia, and now she just transformed herself into something from his fantasies. "...How?" Kain gaped.
A cold glare from Jonathan's draconian eyes brought Kain back to reality. "Keep your eyes to yourself," he said. Unlike Kain, Jonathan knew exactly what just happened with Nyxia. Jonathan and Nyxia had been drinking blood from each other for their entire lives, and their blood strengthened each other in more ways than they had imagined. Jonathan's innate magical powers were significantly augmented by Nyxia's Nymph blood; and right now, Nyxia was using Jonathan's demonic and vampiric blood to transform herself into something stronger.
Among his group of more than two dozens of False Vampires, Mavros began to feel a growing sense of dread. Of course, Jonathan's little trio was severely outnumbered eight to one, but the three of them were much, much stronger than Mavros had anticipated. Especially Jonathan himself; it was no easy task to cut a rift into the Abyss in the sky itself. But Mavros had brought his strongest subordinates to this battle, and he would make sure that Jonathan was terminated. He snapped mental orders to the False Vampires around him. Noxus, your group take care of the Vampyre; Atropos, you can kill the Nymph; Jonathan is mine.
Yes, Lord Mavros, the two False Vampires replied.
