Magus Of Possibilities

Magecraft or Thaumaturgy, is the artificial reenactment of Mystery, which is ordinarily possible only by inhuman beings.

It is the ability to bring about what is possible through science with supernatural means; although the process is considered a miracle, the result is not. The limits of Magecraft have changed with time, as science evolved and Magic from the past became possible through science.

There exists no impossibility for modern Magecraft within the rules of the world and limits of human intellect; there are limitations, however, where it only appears that something is possible. Because Magecraft acts as the reenactment of preexisting phenomena, it is impossible to use it to create new Mysteries; even with an infinite amount of research, there exists a "wall" preventing human wisdom from doing so in the current era. The realm past this "wall" is known as Magic.

It is a power which can be harnessed by Magi(Plural for Magus) for a wide variety of purposes.

Usage:

It is used by intervening and changing Runes, a Magical language used by the practicioner when casting. It is a language specialised in self-suggestion that reforms the deep consciousness field, which is necessary for delivering magic.

It can be written or something as simple as words you say so as to create a mental image of what you want to do. In other words an ȧssociation game especially for magecraft that requires a chant or incantation but it can be something like using runes

The user uses prana a energy which is a combination of mana which is the ambient magical energy and od which is the internal source of magical energy

Both are processed to form prana using magic circuits which are a pseudo-nervous system that spreads itself through the human body and what qualifies a person to be a magus used to produce prana

They are that which connects the material world to the astral plane

Foundation of Magecraft:

Every magecraft has its own set of rules that must never be broken, known as a taboo. Different taboos that are broken have different effects on the user's body but there is something we call the Thaumaturgical Theory into the world and uses the rules of that system to operate their spells. The efficiency of a system depends on how disseminated it is, as in the more people believe or use it. It is not uncommon for a system to not work properly when used outside its place of origin. It sets the foundation for each school of magecraft to create the framework known as Thaumaturgical System

Thaumaturgical System is the general term used to refer to the several modern schools of Magecraft such as Astrology, Kabbalah, Alchemy, and Shinsendou. Divergences can be found among different schools, but the fundamental basis is "to convert Magical Energy inside the user's body to transform the external world". The practitioner acts in accord with the system that each school operates under to execute a pre-built program. That "program" is a set of universal rules that interfere with nature once they are enforced. The power that enforces those rules is the magical energy of the magus and the command to do it is made through his Circuits. The greater the interference, the greater will be the amount of magical energy consumed.

Being originally magic following the rules of Idol Theory which is the term used to refer to the phenomenon wherein an imitation of a whole or parts of a subject, the source, gains properties and attributes that are inherent to that source. It is used as an explanation on how magecraft draw their power from the magic of the past, and how they wield it.

Despite this, even the smallest percentage that is retained by the duplicate is powerful enough especially if it is during a holy grailin a servant a duplicate of a heroic spirit still have a enough power to cause massive damage but this also applies in most magi especially the magecraft that they use

Magecraft is that "which governs the skills of past humans that science cannot explain" and science is that "which gathers the technology of future humanity that sorcery cannot reach." The two disciplines are absolutely incompatible with each other, but they are similar in a single respect. The pursuers of each practice seek continued prosperity, protecting the future of humanity.

The main aim of the Magi's academia is to make the impossible possible. If something cannot be achieved with modern Thaumaturgy, the magi research and develop their arts just for the sake of changing that. Powerful sorceries like High Thaumaturgy and Greater Rituals are ultimately challenges in order to reach the goal called Magic. After a certain point of development, differences between power and even between Magic and Thaumaturgy start to lose their importance in practical terms.
