Vol.08: "Nahida (Buer)" - "Wisdom" and Self-Sacrifice, the Philosophy of Oblivion Borne by the Guardian of Irminsul

Introduction: The Essence of “Wisdom” Governing Teyvat’s Memories and Its Existential Proposition

In the continent of Teyvat, “wisdom” is not merely a term denoting the accumulation of knowledge or academic data. It is the physical and metaphysical record of history through the world’s foundational network, Irminsul; it is the very cycle of life; and furthermore, it is a colossal computational system that determines the fate of the stars. Nahida, also known as Lesser Lord Kusanali (Archon Name: Buer), who reigns as the Dendro Archon of Sumeru, is an avatar created by being plucked from the purest branch of Irminsul. She is a singular divine entity standing on the boundary between “truth” and “falsehood,” and “memory” and “oblivion” in Teyvat.

This article is a research report that thoroughly unravels the philosophical and mythological context embodied by the character Nahida, integrating the vast lore archives of Genshin Impact revealed up to 2026—Archon Quests, artifact texts, weapon stories, in-game books, boss drop materials, and the latest worldview developments in Nod-Krai and Snezhnaya. At the core of her existence lies the heroic self-sacrifice of the previous Dendro Archon, Greater Lord Rukkhadevata, and the existential paradox of a global-scale “oblivion.” This process perfectly traces the fall and salvation of “Sophia” (Wisdom) in Gnosticism, as well as the stages of the Magnum Opus in alchemy.

In the following chapters, we will discuss the full scope of the cosmological destiny borne by the God of Wisdom, logically distinguishing between the “Facts” explicitly stated in the game and the “Theories” derived from the profound body of texts.

1. Mythological Origins — The Manifestation of the Demon “Buer” and the Gnostic “Sophia”

The foundation of Nahida’s character design and ideological background is deeply interwoven with the influences of real-world demonology, occult philosophy, and Gnosticism, which was considered a heresy in early Christianity. There is an extremely clear mythological and ideological intent behind her Archon Name and her position in Teyvat’s cosmology.

1.1 The 72 Demons of Solomon’s “Buer” and the Embodiment of Natural Philosophy

The Seven of Teyvat, as well as the higher entities connected to The Heavenly Principles, without exception, bear the names of demons recorded in 16th-century grimoires such as the Goetia (The Lesser Key of Solomon) and Pseudomonarchia Daemonum. As an in-game fact, Nahida’s true Archon Name is “Buer.”

In historical grimoires and lore, Buer is described as a Great President of Hell who commands 50 legions, possessing the following prominent characteristics:

1. Teaching of Philosophy and Logic: He is a teacher of Moral Philosophy, Natural Philosophy, and the Logic Art.

2. Botany and Healing Powers: He knows the properties and virtues of all herbs and plants, and possesses the power to heal all distempers in humans.

3. Astrological Symbolism: He appears when the sun is in Sagittarius, namely from late November to late December. He is also depicted with the head of a lion and multiple goat (or horse) legs, allowing him to move in all directions like a wheel.

These attributes align astonishingly perfectly with Nahida’s character design and her role as the Archon of Sumeru. As the “God of Wisdom,” she presides over the Akademiya’s scholarship (logic and philosophy), and as the “Dendro Archon,” she governs the plants of the natural world and the regeneration of life. Furthermore, her healing abilities and her role in alleviating people’s mental anguish (and the physical illness known as Eleazar) through dreams are faithful reproductions of Buer’s attribute of “healing all distempers.” The fact that the Amurta Darshan of the Sumeru Akademiya masters botany and medicine can also be said to be a manifestation of Buer’s authority as a social system.

1.2 The Gnostic “Fall of Sophia” and the Emanation of Wisdom

It is explicitly stated throughout the work as a fact that the worldview of Genshin Impact draws strong inspiration from Gnosticism (e.g., the “true sky” and the False Sky, the Demiurge-like creator, the class of Archons). In Gnosticism, the material world (Teyvat) is a cage created by an ignorant, false creator (Demiurge = The Heavenly Principles / First Descender), and the Archons function as wardens managing that material world.

In this mythological framework, Nahida (and her predecessor, Greater Lord Rukkhadevata) perfectly assumes the role of “Sophia” (Wisdom), one of the Aeons (emanations of divinity) from the supreme spiritual world (Pleroma) in Gnostic myth. In the myth, Sophia “falls” from the higher spiritual realm into the material world, resulting in her “divine spark” becoming trapped in a material body.

As an in-game fact, upon her birth, Nahida was imprisoned in the Sanctuary of Surasthana for 500 years by the sages of the Sumeru Akademiya. This has been pointed out in community theories as a perfect reproduction of the metaphor of “Sophia’s imprisonment in the material realm.” Her light (wisdom) was extracted into the material network known as the Akasha System and utilized as a power source to exploit the dreams of the people of Sumeru. Just as Sophia’s fall ultimately functioned as a system to redistribute “divine light” to the ignorant material world, the story of Nahida’s imprisonment and salvation depicts the very process by which “true wisdom” is liberated and brings truth to humanity within the giant miniature garden of Teyvat.

2. The Covenant of the Three and “Gilded Dreams” — Divergent Approaches to Truth and Sorrow

Indispensable to discussing Nahida’s existence is the ancient covenant forged in the desert regions of Sumeru by her predecessor, Greater Lord Rukkhadevata, and two other god-kings. The artifacts “Gilded Dreams” and “Deepwood Memories” vividly record the history of these ancient gods’ ideological conflicts and partings.

2.1 The Eternal Oasis and the Ideals of the Three Gods

As an in-game fact, ancient Sumeru was ruled by three “oathbound friends”—the Lord of Verdure (Greater Lord Rukkhadevata), the Lord of the Deserts (King Deshret), and the Mistress of Flowers and Moonlit Nights (Makhaira / Goddess of Flowers Nabu Malikata)—who built a “worriless paradise.” Their relationship was likened to “the silver moon, the golden sun, and the emerald fields,” and initially maintained perfect harmony.

However, their philosophical approaches to “wisdom” and the “world” were fundamentally different, which eventually led to a decisive rupture. The following table outlines the structure of the ideological differences among the three gods, deciphered from artifact stories and related texts.

Unable to endure the “sorrow” of the Goddess of Flowers’ death, King Deshret attempted to create a dream world where no one would be hurt (Gilded Slumber). The texts of the Sands (The Sunken Years) and Goblet (Honeyed Final Feast) of the “Gilded Dreams” artifact set record a mad plan to deny harsh reality and eliminate sorrow through a mechanical intelligence that unified all calculations: “And from the heart of the machine, within the dark nightmare, a new intelligence shall molt,” and “all humanity shall become the king of kings.”

In contrast, the philosophy of Rukkhadevata (and Nahida) is expressed in the “Deepwood Memories” artifacts. She viewed “dreams” not as a place of escape from reality, but as an incubator of life to heal wounds and provide a “chance to start over.” As stated in the texts of Deepwood Memories, the dream-manipulating spirits (Aranara) and her successors, the large mustachioed cats (Rishboland Tigers), continued to protect the life of the forest even after the labyrinth perished.

2.2 Forbidden Knowledge and the Contamination Mechanism of The Abyss

The “Forbidden Knowledge” that King Deshret touched to transcend the absurd shackles of the heavens (The Heavenly Principles) is a cosmic contamination brought from outside Teyvat (The Abyss). As a fact, because this knowledge does not belong to the laws of Teyvat (Irminsul), the world itself exhibited a violent rejection, which manifested in Sumeru as “Eleazar” and “The Withering.”

The origins of this Forbidden Knowledge trace back even further into antiquity. Before Teyvat was ruled by The Seven, the world belonged to the Sovereign Dragons. There is a fact that the Dendro Dragon Apep once absorbed the power of The Abyss (Forbidden Knowledge) alongside Dragon King Nibelung to oppose the Descender (The Heavenly Principles). The text of the character ascension material “Worldspan Fern,” dropped from within Apep, conveys the memory of the first fern that sprouted in Apep’s garden during the era when the world belonged to dragons. The description, “Eventually, the fern became a tree, became vines, became roots, became leaves, and covered the entire world,” suggests the primordial form of the Irminsul system, or the state of nature prior to it. Furthermore, the texts of “Primordial Greenbloom” and “Everamber” record that after the calamity that fell from the heavens (the Divine Nail), a nameless insect trapped in amber reached the future in eternal silence, symbolizing the existence of life attempting to defy fate within closed time.

The ultimate role of Rukkhadevata (and later Nahida, who inherited it) was to purify Irminsul and Teyvat from this cosmic error, Forbidden Knowledge. Rukkhadevata exhausted her power to quell Deshret’s calamity, regressing into the form of a child. Then, during “The Cataclysm” of Khaenri’ah 500 years ago, even her own consciousness, which had assimilated with Irminsul itself, became completely contaminated.

3. Irminsul and the Mechanism of Historical Alteration — An Existential Paradox

The greatest philosophical and emotional climax in Nahida’s story, an event that shook the entire lore of Genshin Impact, is the “alteration of history and memory.” At the conclusion of the Sumeru chapter, Nahida made the ultimate self-sacrificial decision to completely erase her predecessor, Greater Lord Rukkhadevata, from Irminsul.

3.1 The Time Model as a Tree and the “Reweaving of Fate”

In the world of Genshin Impact, time is modeled not as a single line (timeline) or parallel worlds, but as a “continuously growing giant tree (Irminsul).” According to the logical theories of community lore scholars, intervening in Irminsul is interpreted not as “traveling back in time to create another timeline (time travel),” but as “pruning the branches of the tree, cutting off the diseased parts, and reshaping the entire tree.”

This goes beyond a mere “rewriting of people’s memories”; it is an “alteration of the world’s reality itself (information).” As an in-game fact, Nahida herself states that “changing the information in Irminsul changes Teyvat.” The historical void attached to the erased entity is automatically compensated for by a different causality, and even the physical traces of reality (books, records, motives for people’s actions, down to the shards of a broken vase) are corrected to remain consistent.

3.2 Greater Lord Rukkhadevata’s Self-Erasure and the Limits of the System

Here, a fundamental question arises: “Why couldn’t Greater Lord Rukkhadevata erase herself from Irminsul with her own hands?”

To this, the facts and metaphors within the story present an extremely logical answer. Rukkhadevata was not merely a god, but the very “avatar of Irminsul.” When Irminsul was contaminated by Forbidden Knowledge, she herself was inevitably contaminated. To use a computer analogy, “a hard disk (OS) infected with a virus cannot completely format (erase) itself.”

Therefore, she plucked the purest branch that had not yet been contaminated and created Nahida as her reincarnation (backup system). Only through the “external access rights” of Nahida, who had grown as an independent, pure individual 500 years later, was it possible to delete the contaminated old system (Rukkhadevata) and reboot the entire system.

3.3 The Decisive Difference from the Erasure of The Wanderer (Scaramouche)

This mechanism can be understood more clearly by comparing it to the later case where The Wanderer (Scaramouche) attempted to erase himself from Irminsul.

Because The Wanderer is merely a “creation (a piece of data)” and not an avatar of Irminsul, he was able to access the information layer himself and delete the personal record of “Kabukimono / Scaramouche.” However, he could not physically undo his sins (such as the events at Tatarasuna) themselves; the world merely reconstructed causality as if “he had never existed,” while he himself continued to remain as “The Wanderer.”

On the other hand, Rukkhadevata’s erasure was a global-scale surgical operation to “remove a fundamental contamination bug from the very laws of Teyvat (the tree).” As a result, the entity known as Greater Lord Rukkhadevata completely vanished from the world, and a massive paradigm shift—“Nahida had been ruling Sumeru from the very beginning”—was overwritten into history as a fact. Only the “Traveler,” a Descender unbound by the laws of Teyvat, became the sole recorder who remembers the truth of this history.

4. The Lamp of the Dreamscape and the Severing of Karma — Rebellion Against Causality and Salvation

Nahida is the God of Wisdom, but simultaneously the god who governs “dreams” and “hearts.” Her signature weapon and the events she has been involved in are all deeply tied to an existential salvation utilizing this concept of “dreams.”

4.1 A Thousand Floating Dreams — Aranara and the Boundary of the Void

The text of Nahida’s signature weapon, “A Thousand Floating Dreams,” depicts her philosophy beautifully and literarily. This weapon is a “lamp that illuminates the dreams floating in a thousand nights,” echoing “a song of ancient days.”

The text features a “blind girl” who has never seen light. Amidst a crumbling palace, she sees “breathtaking sights of a thousand worlds” through the world of dreams. A dancer with emerald eyes kissing silk, a moonlit musician guiding a torch, a wise sailor seeking a blooming garden—the dreams of such people are illuminated by the light of the lamp. However, as the light of dawn (reality) begins to pierce through the gaps in the leaves, the light of those dreams gradually fades. The blind girl realizes that once dawn comes, she can never return to the dream. Yet, even if the lamp’s fire goes out, the memory of the “song” and “hope” it brought will continue to illuminate the long hours before dawn.

This is a metaphor for the “salvation through dreams” that Nahida performs through the Aranara, as well as an allusion to the alteration of memories by Irminsul (a dream forgotten upon waking). In dreams, everything is beautiful and can be redone, but humans must eventually face reality (dawn). Her kindness as the God of Wisdom lies not only in confronting people with harsh truths but also in providing “warm dreams” as a cushion to help them endure those truths.

4.2 The Severing of Creation and Karma — Shouki no Kami and the Three Mirrors

Nahida’s existential philosophy was demonstrated in its most grueling form during her confrontation with the puppet who attempted to become a god, Scaramouche (Shouki no Kami, the Everlasting Lord of Arcane Wisdom). The drop materials obtained from the battle with him record the weight of the karma that bound him and the philosophy required to sever it.

Rather than obliterating him, Nahida chose a path that forced him to face the consequences of his own actions and take responsibility for his past of his own free will. This forms a parallel to the process of “atonement for sin (Forbidden Knowledge) and rebirth” that Nahida herself inherited from Greater Lord Rukkhadevata.

5. Rene’s “World Formula” and the Traveler as a “Variable” — Confronting Determinism

Within the lore stretching from the deserts of Sumeru to the Narzissenkreuz Ordo in Fontaine, a colossal concept emerges that stands in stark contrast to Nahida’s “wisdom.” That is the “World Formula” devised by the genius Rene de Petricor.

5.1 Determinism and “Proof from Nothing”

Based on the Forbidden Knowledge and the power of The Abyss he obtained during his explorations in Sumeru (likely in areas heavily influenced by The Abyss, such as Apep’s or Deshret’s ruins, and the Vourukasha Oasis), Rene, along with Jakob, constructed the “World Formula” to calculate the future of Teyvat. As an in-game fact, according to this formula, no matter how many times the calculations were repeated, they reached the conclusion that the end of Teyvat (a destruction where beasts swallow the amniotic sea) was an unavoidable result.

In community lore theories, the mathematical and logical structure of this World Formula is analyzed as a “tautology” and a “proof from nothing.” In natural deduction, a proposition that can be proven without premises is always true (tautology). As long as calculations were made using only the causality of the closed miniature garden of Teyvat (within the laws of Irminsul), the end was an absolutely unalterable Fate.

5.2 The Traveler (Descender) as the Sole “Variable”

However, Rene’s perfect World Formula had a fatal flaw. It failed to factor in “external variables.” The concept of “Descenders,” which Nahida revealed to the Traveler at the end of the Archon Quest, is the very “Variable” that shatters this deterministic World Formula. The Traveler, unbound by the laws of Teyvat (Irminsul), functioned as an irregularity (variable) not incorporated into Rene’s calculations, thereby deflecting the trajectory of Fontaine’s destined destruction.

As the God of Wisdom, Nahida places immense importance on the Traveler—who records the history of Teyvat and is immune to alteration—as the “true recorder who observes the world.” Her wisdom differs decisively from that of Rene or King Deshret, who despaired and fell into madness within closed calculations; in her capacity to accept unknown external variables and possess the “margin” to fight alongside them, she can be said to be the most advanced existentialist in Teyvat.

6. The Latest Threat (2026) — The “Loom of Fate,” the Burning Irminsul, and the Pinnacle of Alchemy

In the 2026 updates (Version 6.x series), the lore of Sumeru deeply intersects with the developments in “Nod-Krai,” the path to Snezhnaya ruled by The Tsaritsa, plunging the story into an unprecedented phase.

6.1 The Return of The Doctor and the Crisis of the “Burning Irminsul”

The fateful connection between Nahida and the Second of the Fatui Harbingers, “The Doctor” (Il Dottore), did not end with their deal in Sumeru (destroying his segments in exchange for the Dendro and Electro Gnoses). As predicted by the community and leak information, The Doctor reappeared in Sumeru and Nod-Krai approximately “1000 days later (Version 6.6)” from the Sumeru storyline.

As a fact in the latest Archon Quest, The Doctor is once again targeting Irminsul. The “dream of Irminsul burning” that Collei once saw is now an imminent real-world crisis, and The Doctor is plotting to burn the Irminsul tree in order to elevate himself to the realm of gods or to directly access and manipulate the Ley Lines of Teyvat itself. The Doctor’s new segment in Nod-Krai possesses none of the intellectual bargaining or probing of Nahida’s expressions seen in Sumeru; instead, he pushes forward with the “elimination of the unnecessary” in an extremely cold-blooded and uncompromising manner.

6.2 The “Loom of Fate” and the Ley Lines of the New World

Proceeding in parallel with this is the existence of the “Loom of Fate,” initiated by the founder of the Abyss Order, Chlothar Alberich, and completed with the consciousness of his son, Caribert, at its core. As a fact revealed in World Quests and Archon Quests, the Loom of Fate possesses the ability to “weave new Ley Lines” independently of Irminsul, creating an “Atlas of the New World” with the power to overwrite the reality and memories of the world.

6.3 The “Rubedo” of Alchemy and Nahida’s Ultimate Destiny

This situation astonishingly aligns with the four stages of the Magnum Opus in alchemy.

• Nigredo (Blackening / Putrefaction): The “contamination and putrefaction by Forbidden Knowledge” borne by Greater Lord Rukkhadevata.

• Albedo (Whitening / Purification): The birth of Nahida and the “purification of Irminsul” through the oblivion of her predecessor.

• Citrinitas (Yellowing / Dawn): The liberation of Nahida and the new dawn of wisdom through the reformation of the Akademiya.

• Rubedo (Reddening / Fire and Blood): The “burning of Irminsul” by The Doctor and the “integration and rebirth of the new world” by the Loom of Fate.

The most terrifying hypothesis debated among some lore scholars is that “Nahida herself might function as an ‘emergency backup system’ in the event that Irminsul is destroyed.” Just as a single boy, Caribert, became the “trunk and roots” of the Abyss’s Loom of Fate, Nahida, the purest branch of Irminsul, faces an existential crisis where she must sacrifice her own existence as a sapling for a new Irminsul if the current one is physically burned to ashes by The Doctor. In the violent alchemical process of “burning the old world” championed by Snezhnaya, Nahida is targeted as the greatest obstacle and, simultaneously, the most valuable sacrifice (material) for creating the new world.

Conclusion: The Existential Philosophy of “Wisdom” Built Upon Oblivion and a Gaze Toward the Future

The story of the Archon Nahida (Buer) is not merely a “tale of liberating a captive princess.” It is an existential journey of self-exploration in which the God of Wisdom herself accepts the absolute contradiction between the “cruelty of knowing the truth” and the “salvation through oblivion.”

She completely erased the existence of her beloved mother and predecessor, Greater Lord Rukkhadevata, who gave birth to her, from this world. In that instant, her predecessor vanished from her own memories as well, leaving only the altered fact that “she had been ruling the world from the very beginning.” However, the very fact that she shed tears without knowing why immediately after erasing Greater Lord Rukkhadevata proves a “truth of the soul” that is not recorded in the system (Irminsul).

“Wisdom” is not about remembering everything and performing perfect calculations. As Rene and Deshret fell into, calculating and recording every event and clinging to the sorrows of the past ultimately invites madness and ruin (the despair of tautology). The true wisdom embodied by Nahida is the courage to sometimes cut off rotting branches for the sake of the cycle of life, and to continue walking the boundary between dreams and reality while harboring incomplete memories and a sense of loss.

Despite standing at the pinnacle of Teyvat’s computational capabilities, she acknowledged her own ignorance and accepted the light from outside (the Traveler, a Descender) as her guide. In the face of the impending release of Snezhnaya in August 2026, and the unprecedented crises of the “Loom of Fate” and the “burning of Irminsul” in Nod-Krai, what kind of “wisdom” will she show the world next? No matter how grueling the self-sacrifice required as the price, there is no doubt that the light of hope illuminated by “A Thousand Floating Dreams” will guide the dawn of Teyvat. Beneath the False Sky, the God of Wisdom quietly continues to walk the most arduous path leading to the truth.
