Regarding Mana, there were lot of theories that trying to fully explain the subject. Some were concerned about the manifestation of Mana in form of magic; such as a simple fireball that widely used by the apprentice of fire magician. Some tried to compare the Mana to the power that granted by the higher being (Divine), such as the blessing ability that were piously chanted by the Church of Freya's benefactor.

Some tried to explore the affinity of the magic itself. What is light ? Why it's in the same time strong and weak against dark ? How Wind affinity allow the user to fly? and Why were Water essential for life? How Fire burn? And How the Earth pull? No one know. But Knowledge progress. Tested by Scholar and Magic-enthusiast for centuries. There is one thing that could be concluded..

[p=center]Mana is energy[/p]

That's why melee-class, where they're perform skills required to have certain amount of mana. The correlation of mana with their magic counterpart were obvious, and would be redundant to be discussed. However, their correlation with their melee counterpart somehow rather blurry. Most of the time melee class perform their action through the use of the stamina; the energy of the body itself. Drawing mana to power the skill were action of strengthening the damage output through the use of external energy were considered...

"And seems the magic formed by structuring mana in certain forms, henceforth magic circle."

"I see..." comment the young elf novices to no one in particular, well except if you count three piles of book in front of him. But since book couldn't talk back -except for certain kind, which surely would horrified the reader- his comment certainly only be meant for himself.

The young elf, had certain... appearances. He was short, 3/4 adult size, with a glistening-yellow blond hair and deep aquamarine eyes. A typical shoujo anime boy wannabe with a lot dose of kawaii as a side(puffy cheek and the bright smile that could bring laughter to the whole neighborhood). His real age of course better not to be mentioned, people have their secret, and secret of the age weren't exclusive to female, right?

Since he was child, he fascinated by magic, turning your constantly-barking neighbor's dog into ant, and step on "it" were a delightful idea, no? If you master teleportation, no one would need to worry to be late to appointment, and world hunger should be an easy, solvable, problem.

However, the most revered, the most true, and the most absolute, law of reality; Science states;

Magic doesn't exist.

It simply could not be exist.

Except perhaps if someone could somehow maintain nuclear fusion and fission reaction without exploding the entire neighborhood (and radiating the rest of the world into cancer-ridden society).

Therefore, instead of building impossibly structured machine that could do just that, it would be more cost-effective just to use magic in place that you could set the rule for yourself.

Virtual reality

Royal Road

Today were his first day, and as any aspiring magician knew, learning about the magic in the library were a first step to become one.

However...

"Seriously?" shout the elf with voice that could be heard in the whole library, terribly annoyed.

"Ck ck ck... Library is a place to learn, child. Not to shout." chuckle the senior librarian who intrigued with the elf constant reading.

"Sorry, sir..?"

"Priel. And yours?"

"Vincent Valitius, sir Priel. I'm sorry about my... inappropriate behavior."

"Ha, try to reduce your sin with nice words! My, my.."

"...."

"That is fine, child. For the scholarly individual like us, there are a point when you stuck in your studies. Even though, the way of expressing the frustration differs from person to person, It would be wise to choose methods that would not disturb other people. Imagine, how you could progress in your study, if every quarter hour or so, someone shout their frustration, hmm?"

"I'm sorry."

"Ha,ha, it's okay. Why were you shouting, if I may ask?"

"err..I was learning magic..."

"And... most of them about attacking! A simple kaboom, if I may be bold.."

"Yes, that's true, this is a secret, but Magician loves... flashy things, and the evocation branch, offer that the most. Well, beside summon-type spell in conjuration branch, but you see my point."

"I know! It's so boring!.... But... hmm... could I make a spell myself?"

"Well, if you know how. Even though... it would be wise to wait until you had enough mana. Creating spell are very taxing process, not to mention the kaboom"

"Oh, not to worry, I could always power it with outside mana."

"Outside mana?"

"Well, it's my made-up term, your mana in the status bar called inside mana. And the mana outside you called, well.. outside mana."

"Are you sure with that.... postulate, child?"

"It's only my conjecture, but how we explain why we regain mana after rest? If energy were really conserved, something should powered our internal mana. Health, satiety, and stamina are not the one which powered it, (magician have practically zero of them, and magician had lots of mana) and we never see the decreasing health or stamina when we rest to regain the mana. Satiety is out the question. If satiety power the mana, it logical to says that bread make mana --Alchemist would be bankrupt, and chef would raise to power-- On the other hand satiety does regen health and stamina, when we rest, we regain our health and stamina, no? But our satiety is lowered. Therefore, the only logical means, mana came from the outside, the environment, the nature itself. Like water that fall to lower place, mana's seeking equilibrium, and transfer to the place with a lower mana, namely ourselves after we use mana consuming skill."

"Mana regeneration are the termed we used to explain the rate of transfer the outside mana to our internal mana, and our internal Mana means our mana capacity. Simple as that. Therefore, rather than using our internal mana. It is possible to just outside mana. Even area of effect magic also powered by outside mana, the internal mana only used to draw the instruction and act as the catalyst, internal mana were often used because it's well.. easier to control. So, even beginner like me could use 7-circle spell, if I somehow could redirect the outside mana to my use."

"I see, i see, hmm how about I lend you my laboratory? It's not much, but I'm sure you could test your hypothesis there."

"Really? Thank you!"

"And this is a little prize for explaining such beautiful explanation of mana to me. Haha, even though you're still a child." said the senior Librarian handing ten gold coins and an intricated golden key.

"Isn't this too much for new freedman like me?" ask the elf, stupefied.

"Research are not cheap you see, just tell me the result, after you succeed, or fail. Ha ha ha. Ehm.. Most importantly, my lab just two street across the library, go there and bring me the good news! "

"Thank, sir Piri! Bye!" shout the elf running.
