"Alright, just...don't tense up and trust me," Glenn tried to reassure his sister, who was sitting cross-legged in front of him. Sahro and Liara were watching from the side, their arms crossed and their eyes filled with curiosity. Both of them knew how special Glenn's Mana Heart was, so they couldn't wait to see what kind of insanity his sister was going to be. The group was back in the Bourgeoisie, in their mansion on Silverhomes.

Glenn closed his eyes and gently channeled his Mana in his sister's body, guiding it through the natural pathways to the Heart. Lina winced, her eyes similarly shut.

"I...I can feel something!" she exclaimed in surprise.

"Concentrate. The faster you get a hold over it, the easier it'll be," Glenn scolded her, digging through the Mana to find her Mana Heart. Her perception of herself was very similar to his, in a very digitalized way. He snorted and grabbed her ethereal hand. She flinched, finding the sensation unexpected.

"I...I can hear you in my head," She frowned. "Like with Tiamanes. It's...not great."

Glenn snorted, "Bear with it. We're going to find your Mana Heart. Keep your focus." On these wise words, Glenn dove deeper into the Mana, bringing his sister with him. It didn't take long for them to find Lina's Mana Heart.

If it could even be called this way. It was a black hole.

But it looked strange, somehow. It felt...disjointed. The more he looked at it, the more he felt like there were two black holes, linked in some inexplicable manner.

"Wow..." Lina's ethereal voice echoed beside him. Glenn snapped his fingers and drew her focus back to him, "That's the most important part. I used a machine for my Conjuration, but you won't, since I'm here. That'll be better for you."

'Probably,' He thought, not daring to say that out loud. He didn't need his sister to worry for nothing. He was almost certain that he knew how a Conjuration happened, and an artificial one using a soulless machine was certainly not the best way to go about it. It was one way, though.

"Ready when you are," Lina said, her fists clenched in determination. Glenn grinned before concentrating. He redirected the natural flow of Mana around his sister and guided it inside her body, connecting it with her innate source of power, the Mana Heart. It took a little longer than he thought because he needed to avoid some weird pink-colored obstacles on the way. Seeing how his sister wasn't suffering from terrible pain like he did during his Conjuration, it looked like his experiment was working as intended.

He sent the Mana around Lina's twin black holes. A bead of sweat pearled down his forehead as he manipulated the Mana as carefully as he could, forcing it to make a circle around the blackholes instead of just shooting somewhere else. The ethereal Mana began connecting with her Mana Heart and started changing form. Lina suddenly yelped and hid her eyes from the sight.

"I...I can't see anything! It's blinding!" She screamed in warning. Glenn didn't let that disrupt his concentration. The blackholes twisted against his will, but they were nothing in comparison to his Milky Way. The Circle he created briefly flashed as a bright strike of light before sealing under indecipherable runes. Glenn held onto the Mana for a few more seconds, making sure everything went as planned, before letting go and getting out of his sister's Mana Heart.

"Phew, that was intense," Glenn sighed in relief as he wiped the sweat off his eyebrows. His back was similarly drenched, and he felt utterly exhausted.

Lina looked at her hands in a puzzled manner, "Is it normal that I can't feel anything different?" She asked with a tinge of worry. Liara chuckled while Sahro snorted.

The Princess walked up to his sister and patted her shoulder, "Don't worry, you'll have a hard time at the beginning, and it'll start coming together eventually."

"Glenn was shit at the start too," Sahro added, before swiftly dodging a flying Pebble, "What was the name of that spell already? The "Bullet of Death"?"

Lina chuckled as Glenn's cheeks reddened. The latter smacked his lips and pointed at Sahro, "At least, I'm not like this idiot who's just conjuring a lot of thunder without any sort of control."

Sahro raised an eyebrow, "And who told you that?"

Glenn looked at the Black Heir, only to hurriedly put up his Saturn Rings, barely deflecting away a lightning strike that fell out of nowhere. Sahro pinched his fingers together with a mocking smile, "I can use spells too, I just don't find it honorable in combat. Using Mana to power up my Aura attacks simply work better."

"If you say so. In the meanwhile, I'm still stronger than you," Glenn remarked as he dusted his hands off. A vein appeared on Sahro's forehead as lightning crackled around his left, mechanical arm, "...What did you say?"

Liara ignored the two idiots and looked at Lina, "First, get a hang of how to use Mana. Then, Sahro and I will teach you Aura, alright?"

Lina nodded with a blush, unable to look the Princess straight in the eyes. Glenn noticed from the corner of his eyes and his lips curved upward slightly. It seemed like Liara's charm was working wonders on his little sister.

'Are you seriously shipping the hot princess with your sister? Loser, you should take her for yourself!' Diamanes exclaimed in indignation.

Nelg grunted, "Sorry Glenn, but he's right. You might lose your chance at this rate."

Glenn dismissed both voices with a dismissive hand wave and concentrated back on his sister He pulled Pebble out of his breast pocket and made it float above his palm. It had barely taken half a second for the stone to return to his cozy spot, despite having been previously thrown at a dumb Black Heir.

"Alright, he's your new goal. For now, close your eyes and start feeling the Mana. Then, shape into a projectile that you want to shoot at our dear Pebble here." He said as he walked away, leaving Pebble in place.

"Al–Alright..." Lina clenched her teeth and eyes shut, concentrating. Liara and Sahro stepped back, giving her the space she needed. Sahro still shot a threatening stare at Glenn, who simply returned his raised middle finger in response. He then activated his Mana Sight, watching Lina as she struggled to grapple with the Mana.

A case of theft: this story is not rightfully on Amazon; if you spot it, report the violation.

'Must be bringing back memories,' Diamanes remarked. Glenn smiled sadly, 'That it does...I hope I'm not as horrible of a teacher as Redan was.'

"His teachings did work," Nelg said, "Look at how strong you are now. And it only took one year."

Glenn shook his head slowly, 'It took much more than just time, Nelg.'

The weapon couldn't retort anything to that.

Eventually, Lina managed to conjure her Mana in a spherical shape. She reopened her eyes, carefully manipulating the unstable spell. Beads of sweat began forming on her face until she eventually attacked Pebble. The orb didn't look too unordinary to Glenn's eyes, that is until it simply blinked out of existence. At the same moment, an explosion engulfed Pebble and disrupted the Gravity Manipulation Glenn was using to make it float. It wasn't strong enough to break the spell, but still sufficient for Glenn to notice.

"Ah, crap!" Lina exclaimed, "Sorry, I thought it would be better, but..." She looked at the unharmed pebble floating in disappointment, "Seems like I over-estimated myself."

Sahro shook his head and snorted, "Don't worry. The day you manage to break that shitty piece of stone, please call me so that I can marry you and learn your secrets."

Lina coughed in embarrassment while Glenn glared at Sahro. The latter rolled his eyes and mouthed that it was just a "joke".

'It better be, or I'll rip him open...' Glenn thought somberly until Lina's deep sigh interrupted him and reminded him that he needed to understand what had just happened.

"What did you try to do with that spell? It disappeared at some point before reappearing on Pebble. How did you do that?" He questioned curiously.

Lina scratched the back of her head and moistened her lips, "Well, I, uh, I kind of got inspired by my Mana Heart and tried to..." She searched for her words, "Shift it to the target, I suppose?"

"Shift it?" Glenn repeated with creased eyebrows, "Wait, did you just teleport your spell on Pebble?"

His sister shrugged, uncertain, "Maybe? I think? I'm not sure, it just kind of worked."

Liara laughed in awe and clapped her hands, "Wow, that's impressive. If you can improve this further, that means you'll be able to deliver explosions anywhere! Imagine attacking an enemy camp, or a monsters' nest. One spell cast at safe distance, and they can't do anything about it!"

Glenn clicked his tongue and calmed down the Princess' expectations, "Actually, they could. Lina, try again?"

The girl obliged excitedly, closing her eyes once more to concentrate on her spell, only for Glenn to flick her forehead.

"What—why?" She complained as she held her forehead. Glenn repeated the words that were once said to him.

"Do you think the enemy will just be standing there, waiting for you to concentrate? Always keep your eyes open in a fight and stay aware of your surroundings," He warned.

She grumbled and went through the casting process once more, her eyes now wide-opened. Her Mana "grenade" appeared once more, before phasing out of existence—Or at least tried to. It reappeared a good distance away from the Pebble and missed its target completely.

"Wait—something stopped me!" Lina exclaimed in disbelief. Glenn nodded slowly, "As expected. I flooded the space around Pebble with Mana, and it seems like it disrupted your spell. But it works perfectly as a surprised attack to...let's say, burn documents, I suppose?"

Lina sighed, "It sucks, doesn't it?"

Glenn shook his hands hurriedly, "No, no, I never said that. It's just limited in its usage, just like how my first spell was. I just made a Magic Bullet as a first spell, trust me it was ridiculously useless compared to your spell."

Liara nodded, "Yeah, you're pretty good. In all honesty, I think you'll be able to reach the Second Circle in maybe a few days?"

Sahro rubbed his chin, "Your brother's time was three or four days if I remember correctly. Good luck beating that."

Far from being discouraged, Lina's eyes steeled up with resolve and she clenched her fist, "Again then!I need to show who's the real boss in this family!"

Glenn laughed, "That's the spirit! Let's increase the difficulty slightly, then!"

Pebble went through all sort of troubles, flung around like a terrible target, mixed with common stones and enduring a few dozen "Mana Grenades" as Lina liked to call her first spell. Glenn couldn't help but notice the similarity between his first and Lina's. Both went for something similar to the concepts of modern weapons on Earth. Maybe he should be thankful she didn't try to conjure an atomic bomb on her first try.

The day went by without any incidents. Janica and Liam joined in on the training a bit later to test out the weapons they had made, using Liara and Sahro as their targets. Both were more than happy to oblige, using the opportunity to train their dodging and parrying skills. It was safe to say that the two Black Heirs were never in danger from the engineers' weapons. A sniper was the scariest when no one knew it was here. Liam wouldn't have been able to put a bullet through a vampire's head previously if the latter had been aware of his presence.

Once Lina was too exhausted to continue, Glenn taught her how to Meditate and enter the sanctity of her Mana Heart by herself, as well as Projection. It seemed like she was gifted with a Mana pool similar to his own when he was at the same level, which was good. That meant she would struggle on the first three Circles and then get an incredible boost in quantity after breaking through the Fourth Circle. Too much Mana at the start could be detrimental, since she could take bad habits of spending too much Mana by spell and not care at all about the efficiency. Fine-tuning each spell was a skill almost as important as the creation of said magic.

The two following days were the same, peaceful for Sahro and his team while very tiring for Lina.

'I have to admit, Redan's methods of torturing his students are quite fun as a teacher. And they even seem to work wonders,' Glenn thought as he watched Lina Meditate instead of sleeping, her face decorated with a fearful expression. The previous night, he had surprised her passed out in her bed, not obeying his instructions.

...Let's just say she wouldn't repeat that experience again unless she wanted to give the moons a closer look. Waking up in the middle of the sky was quite the terrifying experience, apparently.

Finally, at the end of the third day, Lina conjured a new spell. Pebble was flying in the sky freely, controlled by Glenn's Gravity Manipulation, sometimes disappearing out of sight. Lina waited patiently until she suddenly pushed her hand forward in a flash of black Mana. The distance between her hand and the Pebble seemed to be compressed, somehow, and she grabbed the stone, even though she was quite the distance away from it.

Glenn was so surprised he let go of his control of the stone, letting it be ripped away by the girl. The space returned to normal and Lina roared in happiness.

"Haha, I finally got you, you damned pebble!" She laughed hysterically before throwing the stone as far as she could. She then looked at Glenn, the colors draining from her face.

"I think I might have overdone myself..." Lina passed out face first, her fall stopped by Glenn's Gravity Manipulation. He walked up to her and at Pebble lying further away in the training room, shocked.

"Did she bend space itself? Is that actual space magic?" He uttered in awe.

"It does look like that," Diamanes commented with a satisfied tone, "Excellent. We can't have your sister be a boring water mage or whatever. Space is cool, and space is strong. Give her a bit of time and some tribulations, and she might reach your level."

It was Glenn's turn to laugh mockingly, "I severely doubt that. But yeah, that's good news." His gaze softened as he checked his sister's Mana Heart with his Mana Sight.

As expected, she had reached the Second Circle. She already was an Advanced Initiate.

"More talented than me, that's for sure..." Glenn said with a smile. Lina groaned and forced herself up, recovering from the Mana expenditure.

"Glenn..." She muttered, "I think I found a name for my Mana Heart..."

Glenn raised an eyebrow, "Oh yeah? What is it?"

Lina's lips curved upwardly in a familiar, wicked manner.

"Wormhole. It's a Wormhole."
