Notes on Fate's Metaphysics/Magic

[TheRussianBear]

For "Spiritual Evocation" magecraft there is borrowing powers from the past and try to learn them in the present. "Among magi, there are even those who attempted to let personalities of past lives possess their bodies in order to utilize their skills. These are the attempts to transcend time and inherit skills that one possessed before he was born." - Kara no Kyoukai - Volume 7: Murder Study (Part 2) - Shirazumi Lio /5 Though I don't know an example of this happening off hand, but demi-servants are an example of this.

In Babylonia singularity Ereshkigal moved her underworld and was quite literally underground. You could travel to that mythical place. However, this changed.

From this information it seems like the physics or metaphysics in this case? Will change overtime based on the current dominant powers. Hence Age of Gods and Age of Man. But, the word used is suppress. The "world", ayla or gaia, specifically suppresses magecraft. So It implies while you might be able to-do these things it will come at an increased cost due meddling.

Things of the age of gods creatures got put into the Reverse Side or now reside there not specifically killed by the "world" (unless it was an agent sent by the "world"). The environment where humans were just became inhospitable rather than them not being able to exist at all.

• With how Avalon (scabbard) was found, that Shirou had in FSN, and being the actual scabbed lost, rather than being a Nobel Phantasm summoned by a Heroic Spirit, was still functioning.
• "A God Spirit Class Servant should naturally possess Authorities, but to use them in the modern age requires a corresponding compensation to be paid (involving strain/damage inflicted on the user)." Fate/EXTRA material - Encyclopedia: Authority [Miracle], p.179
• "Originally, this holy spear is the "pillar of light" that fasten together the two sides of the world (reality and illusions) itself, and it has been said that, in the unlikely event that this is undone, reality will be tear off from the world." Altria Pendragon (Alter - Lancer) Translation I think the wiki did better describing the effect this will have, but here is the source.

With these facts I think that the physics didn't change, but rather are being suppressed to support a view of how things function. Not believing in things may give them less power, but a fairy can still mess with you in modern times. (Was a plot of an episode in Case Files of Lord El-Melloi II)

Spiritual Evocation:

• "One of the Thaumaturgical Systems that allows one to summon beings or perform spiritual possession." Fate Wiki, Day 4 of Fate Stay/Night.
• Categories:
  • Invocation: a magecraft technique that attracts a higher being/spirit into oneself.
  • Evocation: a magecraft technique that attracts a higher being/spirit to a point in time and space.
• This is an entire field of modern magecraft, so I'd guess there are a lot of Mysteries and ways to get these results. The Holy Grail summoning system uses a very energy-intensive summoning process, with elements of the Second Magic and Third Magic, the Matou binding magecraft, and the Einzbern wish magecraft, all to make a very powerful ritual that evokes powerful spirits. There are many examples of the summoning of, or communion with, lesser spirits, within the series.
• As EMIYA (Archer) shows in Fate UBW, a spirit can come from the future or past. Merlin (FGO) discusses this as well, noting that he can be summoned by the grail system from the future by virtue of 'not being alive' during the era of Babylon.
• Uses:
  • Spiritual possession to gain knowledge or techniques.
  • Spiritual evocation to gain access to certain miracles, magecrafts, Mysteries, or techniques, that are not otherwise available.
  • Independent Manifestation (skill/spell).
  • Partial or complete reincarnation, as seen by Michael Valdamjong, who has his own independent manifestation technique. Invocation, rather than evocation.
• Discussion:
  • These spirits often have thrones. Their souls are said to have been upraised and engraved into human history. Is likely to be an inherent property of Alaya, or an active process done by them?
  • What are some of the mechanics of possession? Surely there are many ways one can use a Mystery to become possessed, but what can that look like?
    • Two souls can inhabit one body.
    • One soul can resonate with another soul in another time and place, to produce a sympathetic relationship or bond.
    • Et cetera.
  • A nature spirit or fairy is often still alive when possessing or interacting with humans. They, like Merlin or Faye have simply come from the Reverse Side of the World. This is not always the case. If a nature spirit is actually dead, is it possible to evoke them back into the world, even if they never had a Throne, a place, in human history? Also, is it possible for a nature spirit to be independent of humanity?

Reverse Side of the World:

• A dimension that exists apart from the physical world, similar in nature, but not composition, to:
  • Imaginary Number Space, which is a dimension of the world that exists alongside but apart from the physical world. If the physical world is composed of real numbers, this dimension seems to be composed of imaginary numbers. This analogy is likely due to the imaginary unit (i), which is always multiplied by a real number in a way similar to how imaginary number space is always constructed in reference to the physical world, with the component of imagination added into the process. Feel free the debate this, sources seem slim.
  • Reality Marbles (especially those comprising the Moon Cell), which are a swapping of one's inner world with the physical world. In the Age of Man, this technique is extremely costly, and temporary.
• The other interesting layer of reality. It sits 'above' the Earth layer of the world, the base, and 'below' the physical world, which has become overcome by Alaya and the Age of Man, as described earlier. https://typemoon.fandom.com/wiki/Texture
• Description: A dimension where spirits still roam, as the environment is still agreeable to them. The Age of Gods still persists, and therefore, Mystery is still dominant over the natural laws established by Alaya, with spells having comparatively high magical return on investment, facing little resistance.
• Note: this is not one single area, more like a collection of dimensions that are similar in nature.
• Gates:
  • 'Avalon,' the sheath of King Arthur
  • 'Garden of Avalon,' the noble phantasm of Merlin, that manifests Avalon on the earth.
  • Whatever Seig did at the end of Fate/Apocrypha, likely some inherent property of dragons. Whatever Jenne D'Arc does to find him.
  • A wish on a Holy Grail.
  • Whatever Bedivere, Shirou, Merlin, and King Arthur do that brings them to Avalon.
  • Whatever Francis Drake did with their ship, The Golden Hind, which brought them to Avalon.
  • A Mystery contained in Wills Codrington's Fairy Eyes/The Marburry Workshop.
  • Physically digging into the earth. In the era of Babylon, this is possible, and you will find yourself in Kur. After the advent of the Age of Man, over two millennia ago, this option seems to be no longer available, as shown in the case of the dragon Albion.
• Discussion:
  • How does the Reverse Side of the World differ from the two imaginary dimensions?
  • How do the three layers: Earth, Reverse Side, and Physical, compare to each other in mechanics or appearance?
  • (sidenote) In the Age of Gods, without the corrective pressure of Alaya, would a Reality Marble just be its own stable dimension?

Note:

• Thanks for pointing to that Case Files episode, would not have considered it!
• Metaphysics is just the study of Physics, which is just the study of physics. How meta!
• This all comes from the Fate Wiki. I won't actually try to cite, because that would kill me.
