[Third Person's PoV]
"Are you okay staying with Eta and studying under her?" Cid asked Sherry.
Sherry nodded her head excitedly, looking very eager to get started.
"Now then before I leave there's something I have to do and give you…" Cid then started explaining to Sherry about the mana core and its ability and how to make it.
"Are you planning on doing it here? My lab and research could get destroyed you know" Eta interrupted with a pout.
"Your right, it's better if we take this outside, we'll be right back" Cid replied, he stuck out his hand towards Sherry, who took a hold of his hand in a shy manner.
Cid and Sherry then started sinking into his shadow and reappeared out by a forest. When they appeared she looked at Cod excitedly "Would I really be able to use Magic like that. And throw fireballs and things like in those fairy tales, without the use of an artifact"
Cid just smirked and summoned a fireball in his palm and threw it in the air where it exploded into a large firework show. Sherry just looked at it in wonder
"It's beautiful" She whispered to herself.
"You ready?" Cid asked to which Sherry nodded and sat on the floor crossed legged. She, with the help of Cid, started making the mana core.
And just like with everyone else he used a drop of both their bloods to finish the process. Which lead to a large mana explosion signifying the completion.
"Woah!" Sherry said in a childish wonder, "I feel amazing" while looking at her hands, closing and opening them again and again.
"Oh by the way you're now immortal" Cid said casually as if he was just telling her the time. Sherry then froze and looked up from her hands and looked at Cid with her eyes widening in shock.
"Wait… what?"
"Yup, anyways let's go" Cid took a hold of Sherry and they reappeared in Eta's lab.
When they did Eta looked at them with a raised brow "Done already? If so then it's perfect, she would be able to try something I've been researching"
"What is it?" Cid inquired
Eta then went towards a keyboard and started typing away until a monitor suddenly appeared showing an image of a magic circle with 4 stones floating around it.
"Is that what I think it is?" Cid was quite shocked at Eta's current invention.
She nodded her head at Cid's question "That's right it's a magic formation. I was thinking about any future members and how long it would take them to reach the appropriate core level.
I thought of many different ideas but this one was the safest. I kept thinking about jewels with a high amount of magic in it but then thought about your lessons on how these jewels were created like the diamond for example.
Which led me to create those stones you see in there that look like jewels. You once taught me that to make a high quality jewel all one needs is a large amount of pressure and extremely high heat.
So I did just that, I used the elements of Gravity, Earth, and Fire with a bit of whole lot of attributeless mana in the center of it all and created this"
Eta went through a few of her things and took out a stone that looked just like a diamond and presented it to Cid.
"I call this a Mana stone. The magic circle is supposed to help whoever sits in the middle of it absorb them into their mana core smoothly. It also uses the mana in the stone to help the body get stronger and more accustomed to mana, making the absorption rate higher and easier." Eta explained rather smugly.
Cid nodded his head at that with a hand on his chin and chuckled which surprised Eta, she looked at Cid in confusion and wondered why he was laughing.
Seeing her confusion Cid shook his head "Sorry for laughing, but I don't think you have any idea just how useful the thing you created actually are and what it entails."
Eta just shrugged her shoulders "I mostly created it to help with the whole core process, that was the only thing I had in mind at the time, when I was done I just fell asleep and haven't really thought much about it when I woke up"
The whole reason I even brought it up was since Sherry just developed her mana core this should help her out."
Eta then started thinking about what Cid could be implying, her brain started running at a quick pace as if gears were rapidly turning, which caused her eyes to widen in amazement at her own creation.
Cid seeing her realization nodded his head with a smirk "That's right… you basically just created a whole brand new energy source."
Cid then held out his hand and created a holographic image using his magic that showed the way Eta created the mana stone.
Cid then started explaining his own thoughts on the matter. "Instead of simply just adding attributeless mana, make some Mana stones with attributes.
For example make a sword add… let's say a ice attribute mana stone by the hilt of the sword and now you basically just created an artifact, a sword that freezes anything that it cuts. You can also make it so that the mana stone is changeable, like you can switch up the elements, you can make these mana stones as some sort of reward system. There are a lot of ways you could use these things, and that was just me giving an example."
Eta then got really excited, so many ideas kept coming to mind, her thoughts were processing things rapidly. As an idea formed in her mind a new one took it's place.
She turned towards Sherry as she said "Get ready we're starting right now, I'm quite excited about this"
Eta then took a hold of Cid and pulled him in for a kiss and she let go she turned around and went typing away jotting down her different ideas.
Cid seeing her antics just shook his head and turned towards Sherry "When she discovers something new she becomes quite excited and researches it until there's nothing more to research"
Cid then pulled Sherry into a kiss as he said, "Well I'll leave you to it don't hesitate to call me if you need something or just simply want to spend time together, Eta will teach you on how to get in contact with me"
Sherry, whose face was red due to the kiss, nodded her head shyly and watched Cid leave the room.
When he left Sherry turned towards Eta and walked up to her ready to start her mentorship under her.
