"Hold, hold on!... The Third Magic is soul materialization!? But, if that's the case, Servants ought to be cases of materialization of the soul!"

"No. Yes, the base of the system is using parts of the Third Magic, but Heroic Spirits are still only summoned spirits.
Servants aren't living here as beings of this era. They're incomplete as the embodiments of the Third Magic, and Heroic Spirits can still take form without the power of Magic, as long as there's a host."

"Heaven's Feel" isn't a technique that reads and processes the soul of someone from the past in order to make a copy.
It is the power to create a higher existence, one that can interfere in the material plane on its own while being a mental body.
Making the soul itself a living being, and sending it on the next step as a life form."

"The ne...next step...th...yeah, that's incredible, but."
"But, Ilya, no matter what the difference is with the kind of magic, all magic are roads to Akasha aren't they?! What does that have to do with the Holy Grail?"

"No, not even that. There's only one spiritual ground in Japan that can activate magic.
The Fuyuki leylines might be top-class, but there isn't a large enough distortion here to connect to Akasha."

"Yes, the distortion isn't sufficient enough to reach it. That's why, a hole has to be made. If the road isn't linked, then there's no other option other than to break the wall, correct?"

"The process of breaking that wall is the Heaven's Feel ritual. A part of the process of that is linking "enough power to grant any wish", but to the Einzbern, that's only secondary and nothing more than an advertisement for drawing in Masters (sacrifices)."

"What the Einzbern needed was only an enormous circle that could store a massive amount of Prana, outside the eyes of the Association. The Tohsaka head at that time supported them in this. After all, there are only a handful of first class mystical grounds after the Aozaki lands.
To the Einzbern, Fuyuki was a nearly perfect testing ground that met their conditions."

"The two of you should comprehend the rest now. The grails that preside over the wall are broken up into two kinds. The grail sleeping within this land and the grail prepared by the Einzbern. The former is the circle using the Tohsaka spiritual ground; the Greater Holy Grail. The one the Einzbern prepare each time as a key is called the Holy Grail."

"The Greater Holy Grail manages the Heaven's Feel system and the Holy Grail takes in the souls of the defeated Heroic Spirits and is the furnace that moves the Greater Holy Grail.

"When enough souls are stored in the Holy Grail for the activation of the Greater Holy Grail, it uses the souls of the Heroic Spirits, beings from the "outside", to open a gate.

The moment those spirits, who completed their role, return to their original "throne", the slightly opened hole is anchored by the power of the Greater Grail, and opens a path to a place that no mortal can reach, Akasha."

"This is of course, only the first step. Just opening a hole won't give us what we want. The road to Akasha is too far."

"But even still...the one who obtains the Holy Grail will get their hands on an inexhaustible amount of energy.
After all, there's a tremendous amount of Mana scattered over there that no one has yet to use, far more than the amount in this land. To a normal magus, just this is enough to consider a "miracle".
