Author's Note: I forgot to state in the last one that Amanda is 19 and Castor is 13, as it is just after his birthday. In this one, Amanda is 23 and Castor is 17.


His face was scrunched up, yet it was a smooth plane. The magic coming from his body astounded even himself. As he had never shown this amount of aptitude before. But then again, his father had a fair amount, though it was never really acknowledged or shown. So, that was another thing he got from his father as he flicked his small saber and constantly rewriting the Runes before him to keep up the barrier. His uniform was sticking to his sweat-slicked body. The need to protect was strong in him.

"DAMMIT. Cock munching, ass-faced, bottom feeding, dick sucker!"

Castor smiled at his sister's rather foul mouth. Though he knew it was warranted. Her magic was a magnet for trouble. More so since she was now able to gate in her spirits one after another up to six days. Only twice if she used a Gold Key. Which she now had two of thanks to Yukino. A gift since Yukino's kids were both dragon slayers and the last pregnancy almost killed her. Then there was that black key for Ophiuchus. Which wa week magic use?

"You know Dad would faint at that language, right," he quipped as he flicked his wrist and rewrote the runes again.

"Yeah, well right now, dad is not my worry, Castor. This stupid cultist dark guild is," she bit back.

Giving a wry chuckle as he watched some type of magic being released and slamming into the rune shield, causing it to wiggle and wobble like jello. Making his brown eyes goes wide as he felt a feral smile curl his lips. An idea coming to his mind. It would be dangerous as he was only just learning how to control it, but hey, it if saved his sister, their companions, and his fellow rune knights he would do it. Own life is damned.

"Amanda, I need you to close all gates and send those spirits back," he yelled at her as the shield rolled and jiggled. Warping the view through the slight green shield.

"Castor!?" she answered, looking back at him.

When he saw her eyes go wide as they met his own, he knew that she knew what he was going to do. Fear flashed in her amethyst eyes as her body shook. Then she gave a small nod and began to ask her spirits going back. Her body shifting to the side as she pulled the rest of her magic to her and focused it outwards putting a golden barrier between him and her, along with their companions who looked confused.

"Oi, looky the kiddies are gonna try something."

At the words, he whipped his head around and let out a low, dark laugh. His magic had evolved as well. And Uncle Freed had been both proud and horrified when he had shown he too could use Ecriture. Just his was not Dark. Nope, his sister was a Celestial Mage. So, he had taken his deeper. Flicking his wrist he slammed his saber into the loose dirt at his feet. Mentally apologizing to his father for having to do it.

Pulling in his magic, concentrating it as the cultist continued to slam at the runes. Which was cracking now that he was no longer feeding them and changing them? The moment he had enough, Castor looked up flashing his teeth as he hissed through them. Ecriture: Abyss! Then his world swam in shades of gray, white, and green. Pain exploding from all over his body as it twisted and perverted into a creature that had nothing but blood and death on its mind. Making him fight to keep control.

The moment his four large black and green wings formed the Rune Shield went down and he sent a quick look at his sister, who nodded her head. She would do what she had to do. Their bond was something that none could deteriorate. Their magic showing opposing ends of the spectrum. Light and dark. Good and evil. When he turned to look back at the cultist he saw horror, fear on their faces. He could smell it and it made the dark magic encompassing his body swell with happiness and need. It was almost euphoric.

While other cultists were on their knees as if praising him. Castor didn't care, he darted forward, swinging out his arms. The clawed hands easily tearing the souls from the men and absorbing them. This is why he didn't want to use this part of his magic. It took Souls of humans as sacrifices. Dangerous, but his sister balanced it out. In less than a minute Caster had literally ripped every last soul from the cultist. Then as his body turned he saw his sister, her body glowing like the sun itself as she approached him. Her amethyst eyes filled with tears as she reached out with her magic to touch his.

Causing the magic to jerk back, distort as pain exploded again all through his body as he began to grab control of himself. When the pain reached critical, Castor saw his sister holding his larger body to her, rocking him. Soothing his hair back as he smiled and fell asleep. Knowing he was smiling. Because they didn't always get along. Just like any sibling set. But he knew his connection to her was on a deeper level that many misconstrue. He would always be safe if she was there and vice versa. Because Ecriture: Abyss was created to save her ass as she laid dying due to a different dark guild two years go trying to sacrifice her.


Lahar and Lucy went still, cold shivers running up and down their spines as they looked at each other. There was an unspoken conversation before Lahar had his arm around her waist and was using Runes to teleport them to the Magic Council. Which they saw was in an uproar. Never a good thing.

In a matter of minutes, they were in the new head of the Council's office, looking at a long time friend Mest 'Doranbolt' Dryder. Who looked beyond pissed off. Confirming their sinking feeling. Their son had released his most powerful Rune Magic. And they had not quite told the council he could use the Ecriture just yet.

"Oh, you both have some explaining to do," Mest said as his dark eyes leveled on them in pure rage.

With a quick look at each other, a small nod of their heads, they began to explain the distorted black magic and how it was related to their son, daughter, and family in general.
