Shirou sees a book with bags underneath below the wood he smashed.... along with a few words... Norikata Emiya... Shirou stayed there on his knees looking at the words 'Norikata Emiya?' Shirou thinks 'Was he Kiritsugus's father' Shirou continues thinking 'Why was it hidden?' wanting to find out why it was hidden from him he picks it up and open's it and starts reading.
''Kiritsugu Emiya in case I die or be found by clock tower..." 'Clock tower' Shirou thinks in confusion ' Does he mean the tower in Hong Kong? Why would a tower be looking for him ? ' but Shirou shrugs those thoughts off and continues reading ".... Before I taught you anything. I left as much of my Mysteries, Magecraft, and Knowledge about the Moonlit world in this book as I could...." ' Magecraft? Does he mean magic?' ''... But first I Have to say this... TO BE A MAGUS IS TO WALK WITH DEATH... ''But Shirou doesn't think of this as anything special since he already died and been in hell already what got him more interested is that he called himself a magus instead of mage is there a difference? "... meaning anything can kill you.... you're magecraft can kill you, you're friends can kill you, you're family can kill you, other researchers will be trying to kill you to learn your mysteries, even the planet will kill you... And make sure to keep you keep Magecraft/Moonlit World secret or clock tower will kill you."
So be careful and I understand if you don't want to learn anything about the Moonlit world and be ignorant of it..." '..... If... Can I. Maybe... Is it possible to heal Kiritsugu with magi- Magecraft ?' Shirou thinks 'Can ... Can someone like me even learn Magecraft on his own ?' Shirou continues while losing his confidence... until.
"NO! I HAVE TO learn it... I HAVE TO SAVE her... I promised I will become a VILLAIN TO SAVE HER !'' gaining his confidence and more. He turns the page and starts reading " First to become a magus you have to activate your magic circuits. Magic circuits are like a nervous system that while physically able to be seen in your body are actually a part of your soul, there is much we still do not know about magic circuits but what we do know is they convert your Life force into Magical energy called od while also combining mana from the surrounding area around you to make prana the energy you use to activate your mysteries.
This is a small explanation of what I know about magic circuits but I will explain it in detail in the book further and maybe even more if I find out anything else about them anyways what I'm about to say is important. Not everyone can activate their magic circuits I don't know why but not everyone can activate their magic circuits, -even from prestige's family's like the Aozaki who was a renewed family with a nice quality and quantity of magic circuits but hadn't had a child able to open their magic circuits for 3 whole generations.
Ah, so much time and potential research wasted...
But it has been found out that descendants of people who unlocked their circuits have a higher percentage of chance of activating them. It's also recommended to activate your magic circuits at an early age since with age they can be degraded and there is no way to repair them.
Ah... right. While I did mention it earlier, I should go into a bit more detail: people have a set number of magic circuits since birth. Although it's possible to acquire artificial magic circuits for a moment most known method is to consume your nerves to create a magic circuit for a moment. But it's not worth it since you will permanently lose a nerve for one low-quality magic circuit, so use it in emergencies when you have no more od inside of you. As you might have noticed earlier I said a LOW-QUALITY magic circuit, that's because everyone has their own quality of magic circuits.
Their quality is also determined at birth but unlike their quantity - usually -, their quality, as I said before, can be degraded by a number of factors like age, overuse, curses, and so on. This is dangerous because if magic circuits degrade too much, they can become unstable and start destroying the body their in. With curses, it's even more dangerous since the person will become incredibly sick start coughing up blood, and blackout for years until they die...
" Wait.... what? its... its the same as Kiritsugu !" Shirou screamed realizing he found out the cause of Kiritsugu's pain is a curse 'Is there a cure ?' Shirou thinks while continues reading hoping to find a cure "... Although it can be stopped but the people will normally live only for a couple more years because the circuits would degrade by the time so much that they can't hold the soul to the body, and a human can't be alive without a soul.... again usually... There is also no known way to heal or recover degraded circuits..."
''no...noo... nooo! It can't be! There has to be a way! NO! I WILL FIND A WAY TO SAVE HER !'' Shirou screams louder than before " I WILL BECOME A MAGUS AND LEARN A WAY TO SAVE HER !" and continues reading.
...I hope what I said made you realize how dangerous messing around with magic circuits is. To unlock Magic circuits normally you need another magus to force prana inside of you forcefully activating your magic circuits, hearing this you might be wondering how people activated their magic circuits before, and the answer is they were born with them activated, or they're ancestors were from phantasmal species like an incubus, or they had mutations that forcefully activated their circuits. Now, I know you won't know anything about what I said, but don't worry I wrote better explanations in future chapters.
Now you might be wondering how you will activate your magic circuits and the answer is the symbol you see at the bottom of the book. It's a thaumaturgical circle.
Made for absorbing mana from the surrounding area and forcefully putting it into the object that is inside of the circle.
To make it you need certain materials but mostly lead paint since lead is, while nowhere near the best, is good for conducting mana, so with the circle forcefully putting mana inside of you, combining with your life force - Od- into prana thus forcefully activating your magic circuits.
Attention !!! While your magic circuits are activating make sure to create an image or a sound or anything you can think of to create an activation or deactivation switch for your magic circuits so that you won't always have them active and overheat yourself or degrade your magic circuits. The image can be anything from a lightning strike to a howl of a wolf, to even your heart exploding spontaneously.
But make sure you create an image. I also recommend you allow the thaumaturgical circle absorbs mana for at least a day to make sure it has enough mana to forcefully activate your circuits.
Anyways I'm pretty sure I explained all the dangers of the circle and here is the list of resources and ingredients you need to create the circle.....
Now go and activate your circuits. "
Shirou finishes with a blank look.
