The Third Magic was originally achieved by the Einzbern family, but its secret was lost one thousand years ago. In relation to the other Five Magics, it is said the Third "showed the future", and that it would have been best if its discovery had been the last. For the next eight centuries, the Einzberns sought to recover it until finally coming up with the concept of Holy Grail War. There is no information on the original practitioners of the Third Magic. If it can be considered to have any user in modern times, it would be Justeaze Lizrich von Einzbern, who is the core of the Great Grail. Illyasviel von Einzbern also makes use of it in one of the routes of Fate/stay night, although it is an incomplete usage.
The soul contains the memories, mind, and magic circuits of a person, and it uses the person's body as an anchor to the world to keep from being dispersed and returning to Akasha. Once the brain and body are destroyed, it is impossible to restore a person's dispersed soul, and even the magical ability of the Holy Grail can't restore a destroyed body. Even if a magus manages to place their soul into a new body, it will either be an inferior copy compared to the original, as in the case of Michael Roa Valdamjong, or the soul itself will eventually begin to rot, as with Zouken Matou.
Heaven's Feel is a magic that allows for the materialization of the soul (魂の物質化, ?), which stops the inevitable dispersion of the soul once it no longer has an anchor to the world, and essentially makes it transcend to a higher form of existence. It is a magic that realizes true immortality by making the soul into a high-dimensional planar being capable of interacting with the material world as a mental body without having to return to Akasha. The practitioner will acquire an unlimited source of magical energy due to the soul becoming analogous to a perpetual motion machine.
The Great Grail uses several parts of Heaven's Feel in an attempt to recreate it in its entirety. Using an incomplete version, it takes a raw soul, raw energy made from spiritual particles, and copies information of Heroic Spirits in order to generate Servants. Rather than being actual resurrection, it is the temporary formation of a soul that doesn't require a real body, meaning that they are not truly brought back to life. Gaia, considering that they should be dead in the present, considers servants to be a contradiction that must be removed, so they need a constant connection to their masters' magical energy to keep from being erased. After a Servant is killed, the Holy Grail temporarily stores their souls before they are returned to Akasha. In the case of receiving an actual body from the corrupted Grail, they are able to exist for a longer period of time, but they are still considered as not alive and require magical energy to remain in the present world.
During Heaven's Feel, Illya uses an incomplete version of the Third Magic in order to keep Shirou's soul from dispersing after his body is destroyed. While it manages to save his soul, the new container, which she calls "cheap", cannot be fully reproduced from Illya's body. It is small enough to be "plucked" out of a river by Rider, so they have to take the time to find a suitable puppet body for him instead. In such a case where the soul gains a new anchor to the world, anything with similar properties to a human, such as a puppet body or anything else with a brain, the soul will reshape the body according to its memories. This means that the person is now alive, and that the body will bleed, get sick, age, and eventually die. While the person is completely anchored to the body, the soul is actually controlling the body by "remote control."
The existence of Angra Mainyu as the root of all evil, his soul having been turned into an "eternal generator", is an example of what the Third Magic is capable of accomplishing, though that was a result of the wish granting aspect of the Grail rather than Third Magic. Existences like Lugh Beowulf are similar to what the Third can accomplish, but he is a naturally occurring being.
Dress of HeavenEdit
The Mystic Code of the Einzbern family, the Dress of Heaven, is the heart that controls the Great Grail that is capable of materializing the soul for several seconds. This allows for the transferal of a soul into another container, such as when Illya places Shirou's soul into a doll in a bad ending.
It has the appearance of a white dress that is made from gold, and is fitted with seven rings that are said to have control over creation and the souls of others. The seven holes on the dress are the transformed rings and with each Servant soul absorbed, one hole is lit. As a person will be turned to gold if in contact with it, its operation must be conducted by elementals, demi-humans or homunculi.
The Dress of Heaven is transmuted from the ether that forms Illya's personal maid Leysritt. Leysritt was previously a candidate for the Lesser Grail, but was deemed a failure. Despite being a failure, the Einzberns capitalized on Leysritt's lingering innate power as a Grail and converted her to a potential Mystic Code that can augment Illya. The moment that the Dress of Heaven materializes, Leysritt ceases to exist.

 Fate/complete material III: World material - Theory of Magic - Magecraft: "Magic" making the impossible possible, p.048
"Magic" making the impossible possible
True Magic. This is a different mystery than magery. Magi call the events that are unachievable by magery and science in that age True Magic. If that event could be achieved by time and resources, then no matter the difficulty, that event will not be seen as True Magic.
When the civilization of mankind was still young, all magery had been True Magic. But along with the advancement of science, the number of things that "could be done" by people had increased, and in exchange, True Magic diminished. The number of remaining "True Magics" in the modern era are extremely few, only 5. In "Fate/stay night", the achievement of one of these, the "Third True Magic", occupied the portion of the Grail War that could also be said to be its base.
All magi strive to arrive at "True Magic". Even if they can't reach it, the next generation will. Even the next generation can't reach it, then the one after....and like that, thus was weaved the history of trial and error of magery.
First True Magic One of the oldest True Magics but the details about it are unknown. What it involves appears to be common knowledge to some magi of privileged rank. The user of the First has already passed away, but it is said that the person that would be his heir is still alive, barely.
Second True Magic -
Third True Magic Materialization of the soul, in other words, the magic that realizes true immortality. When accomplished, the practitioner will acquire an unlimited source of magical energy due to the soul becoming analogous to a perpetual motion machine. This is the Magic of the Einzbern lineage, and the Holy Grail War was established to acquire this Magic.
Fourth True Magic Like the First True Magic, the details about it are unknown. What it involves hasn't been heard of either. But, the currently existing wizards, when pointing out to the Fourth True Magic, they'll all say "it is there for sure", and will agree that it exists. Also, they don't know the name of the user either.
Fifth True Magic -
•The Five Magicians
There are five True Magics left in the current age. Those who use them are called "Magicians". The user of the First Magic, the oldest True Magic, is said to be dead, so the ones that are "still alive" are four. Let's say that "what had been possible only by True Magic" then becomes achievable by developments in magery or scientific technology. True Magic will be lowered to a mere "craft". Many True Magics were lost from the world like that. Then, can the power of "True Magic" only fade out hereon? No. The arrival of magi at existing or as of yet uncharted new Magic can allow new True Magic to be born and the numbers to be increased. Needless to say, this is far more difficult than a camel passing through the eye of a needle and finding one speck of a jewel in a desert. However, it's not impossible. The existence of the Wizards is proof of that. Thus, magi strive for the heights of True Magic. Believing they will one day reach the stars in the skies with their own hands, they continue dedicating themselves to their studies daily.
•Death of True Magic, Death of a Magician
A Magician, just like a magus, has a long life. If one uses life-prolonging magic, it wouldn't be impossible to live a few hundred, a few thousand years either. But, the "end" will come for sure. Then, would the death of a Magician mean the death of the True Magic he uses? No, it would not. True Magic will be passed on to the inheritor of the next generation and will not disappear. If True Magic were to die, it would only be when it could be realized by normal means.
