SUMMONING
The Ascians teach (a specific form of) the art of fashioning entities from aether, often called (along with other dark arts) the "wisdom of the paragons".
Fundamentally, such entities are pretty much the same: extremely over-powered elementals whose manifestation and maintenance invariably draws upon the aether of the land until its balance is thrown into chaos. They corrupt the hearts and minds of those they blast with concentrated internal aether (or, in many cases, those who spend too much time hanging out close to them, within some kind of corrupting aura).
I use the word
deiform to open an umbrella over all of these beings, because other words have unique and incompatible connotations.
Deiforms are the perfect tool for the Ascians' ambitions. If they are pitted against threats that might undo them (often one another), their patrons will become more desperate and zealous, striving to summon more potent incarnations. (Recently, Elidibus has seemingly taken to the idea that they can be so utterly defeated as to break the patrons' faith and drive them towards a new god. Hints to this come and go, but have not come to fruition.) Even if a deiform remains relatively inactive, however, maintaining corporeal form will still hurt the land in time. Therefore, it seems that the wisdom of the paragons is itself the problem, the methods
designed to create such inevitably damaging beings.
A deiform summoning consists of three ingredients:
- The Beacon: Spiritual Aether: Faith, Prayer, Willpower - Desire.
- The Catalyst: Corporeal Aether: Crystals, Ambient Energy, the Land.
- The Essence: The de-materialized "soul" of a primal, cast into the Lifestream and shorn into uncountable pieces. Often (if not always), the aetherial "atoms" of a being that once lived are drawn together and re-materialized. In such a case, the original being is still dead; the summoned being is at best a shade of its former self and at worst a corruption so severe as to be unrecognizable. It is presently unknown if a deiform can exist without a core of something that once lived, or if essences can be manufacted ex nihilo and re-materialized from there.
THE SUMMONED
No matter what belief system is utilized in the summoning, the result is NOT THAT THING, but a deiform wearing its shape. It is a shade - a thoughtform. In many cases, evidence has later surfaced suggestive that a given deiform has a core of a specific mis-remembered and heavily corrupted historical being.
The appearance, behavior, and temperament of a deiform is determined not only by the faith of the summoners, but their present state of mind. Thus, the summoned being can be whimsical or calculating, philosophical or brutish, isolationist or expansionist, protective or vengeful, and anything in between.
However, while the wisdom of the paragons seems fit to corrupt any belief system, nuances tend to manifest.
The beast tribes of Eorzea believed in
primals, elemental beings that existed at the dawn of time and gave birth to the world as they know it. While we still call all summoned beings by this name, only this subset seem to be the "true primals", the Banshin.
Shiva put a spin on this, with Ysayle and her heretics being manipulated into combining the knowledge of primal existence and basic summoning theory with Iceheart's understanding of Saint Shiva's soul and her personal interpretation of Halone. She became a vessel for this essence through the power of the Echo.
This process was replicated with
King Thordan. The archbishop (who to this day I suspect was granted the Echo by Elidibus) harnessed 1,000 years of deifying and worshipping Thordan I and his Knights Twelve as an Ishgardian saints.
The
Phoenix was implied to be a "pseudoprimal" (that specific word only used in one client language), or manifested as "primal-like power". A massive amount of free-floating aether (drawn by Tupsimati but fed into a spell broken by Bahamut) resonated with the prayers of Eorzeans and were focused on Louisoix, infusing him with power that took the form of the legendary phoenix, a symbol of his deepest desire: Eorzea's rebirth from the ashes. The Leveilleur twins seem to fear that if the truth of the Coils was revealed, the commonfolk would try to re-summon Phoenix to complete its restoration of the realm, thus re-materializing their grandfather's soul and corrupting him into a true deiform.
The false
Shinryu seems to be a similar case; the aether of Nidhogg's eyes and the battlefield, combined with the raw desire for vengeance against the Empire by the deceived and broken Resistance, triggered with Ilberd's focus and death. However, because Ilberd was not a mortal infused, who retained sentience and subsequently died, it is likely that Shinryu is much closer to, if not, a true deiform.
Alexander's origins are complicated; a deiform summoning was simply the most convenient way for the Illuminati to bring their warped understanding of the Enigma Codex to fruition. It was based on the ideals of Quickthinx and ostensibly benevolent (Light, Creation, Judgement, etc.), but any bias or nuance that might inherently have existed in the primal seemed to have been overridden by its status as a perfect calculator and time traveler. Finding no way to perform any action or make any change to reality without doing more harm than good, Alexander set into motion events that would undermine its own existence and render it trapped in a contained and stable time loop, minimizing the damage to the inevitable.
In the Third Astral Era, various beings were summoned as representative champions, warring against one another and later used to resist the Allagan Empire. These were called the
warring gods, or Toshin. Allag called them Eikons (icons, false gods), a name that Garlemald co-opted and used to describe the deiforms of Othard and Eorzea. The three greatest warring gods were dubbed the Warring Traid, but far more existed. Many were defeated by Allag, some may yet be bound.
FINALLY, LAKSHMI
Hand-waving the solo-summoning of Titan by Ga Bu seemed plausible enough. Titan had been summoned there many times before, a ritual to summon him was being prepared, those preparing the summoning were present, and Ga Bu's dead parents were being used as ritual foci. The pump was primed. Usually you need a group, but Ga Bu's Titan still had an unstable amassing of faith - and Ga Bu's Titan was itself weak and unstable.
Lakshmi is spontaneously summoned by a single Ananta after her daughter is slaughtered as a distraction by Fordola, who was trying to flee Castellum Velodyna. Many Ananta across the Qalyana and Vira worship Sri Lakshmi, but no ritual was prepared, few are present, and only the Qalyana broodmother beseeched intercession.
But even this I can handwave to a degree. The Ananta are profoundly adept at magicks. Yoshida went as far as to imply that the Allagan Empire specifically targeted them for use in creating the Lamia. As the inheritors of Lakshmi's fertility and beauty, they utilize these magicks to weave metal and crystal into jewelry that they believe are reflections of the soul. A powerful Ananta, wearing such jewelry, might be adequate to manifest the appearance of the primal which was then fed by others; especially once she'd tempered a few and had been gifted with crystals.
