Vol.16: The Knave (Arlecchino) - Blood of the Crimson Moon and the "House of the Hearth". The Solitary Philosophy of Burning Away a Maddening Fate (Curse) to Protect the Illusion of Family

In the hidden historical framework and cosmology of Teyvat, few entities embody a philosophy as deeply personal and existential, while being so intimately connected to the depths of The Abyss, as the Fourth of the Fatui Harbingers, “The Knave” Arlecchino (true name: Peruere). The bloodline she bears is a remnant of the lost, oldest dynasty of the godless nation of Khaenri’ah, and the power residing within her possesses the capability to incinerate the very boundaries separating the outside and inside of the world.

This report synthesizes the vast mythological and historical fragments surrounding “The Knave” Arlecchino, based on the latest historical excavations (Archon Quests, artifact sets, and abyssal lore) as of 2026. It unravels the origins of Khaenri’ah’s oldest bloodline, the “Crimson Moon Dynasty,” and the cosmology of the moon goddesses, her blood-soaked feud with her predecessor, “The Knave” Crucabena, as well as the structural transformation and her ruling principles within the House of the Hearth. Furthermore, it comprehensively analyzes the essence of her philosophy and abilities based on alchemy (Rubedo), Gnosticism contexts, and the subversive references to the Commedia dell’arte. What emerges from this is the figure of a solitary sovereign who, despite her body being consumed by madness and curses, defies the Loom of Fate by her own free will and desperately defends the illusory miniature garden known as “family.”

1. Cosmological Origins: The Tragedy of the Three Goddesses and the Birth of the “Crimson Moon”

To truly understand Arlecchino’s origins and the source of her power, it is necessary to trace the history of Khaenri’ah, which existed beneath Teyvat, back to its earliest mythological cosmology. Her unique power and existential significance are deeply rooted in the myth of the “Crimson Moon,” which emerged at the intersection of Teyvat’s astrophysics and the laws of The Abyss.

1.1 The False Sky and the Three Sister Moons

In the ancient night sky of Teyvat, three sister moon goddesses named Aria, Sonnet, and Canon once reigned. They were created by the primordial creators (during the era of Nibelung and Phanes) and were beings who brought dreams and songs to the world. However, during the “War of Funerary Flame” that erupted between the primordial creators and The Heavenly Principles, these moons met a tragic fate, being either destroyed by The Heavenly Principles or banished beyond the False Sky.

During this great war, the goddess Sonnet of the “Iridescent Moon,” said to be the smallest and youngest of the three sisters, committed the world’s greatest taboo to escape the fear of death and the despairing agony of her moon being shattered: she fused her fading soul with the power of The Abyss. Through this fusion, she barely managed to cling to life, but at the cost of transforming into an entity tormented by eternal agony. The moon, corrupted by The Abyss, became known thereafter as the ominous “Crimson Moon.”

1.2 The Dawn of Khaenri’ah and the “Crimson Moon Dynasty”

Eventually, the people of Khaenri’ah, who began to build their own civilization deep beneath Teyvat, discovered this Crimson Moon sunken in The Abyss and established the “Crimson Moon Dynasty,” utilizing it as a primary conduit connecting to The Abyss. This dynasty was the first ruling class of Khaenri’ah, existing prior to the Eclipse Dynasty—to which Dainsleif and others belonged—that later bore the familiar “Black Sun (Black Star).”

The Crimson Moon Dynasty was an era that actively researched powers from outside the world (The Abyss and objects arriving from the Sea of Stars) and mastered alchemy and biological weapons such as the Rifthound (Black Wolves). Their ultimate goal was to discover or create “one who transcends the gods”—a Descender—possessing the power to rewrite the Laws (fate) of Teyvat.

The in-game book Perinheri records the full picture of a top-secret institution from this era as a mythological allegory. The sages of that time, with the king’s permission, established a facility to house foreign orphans who had fallen into this world from the Sea of Stars. This was the prototype (initial iteration) of the modern Fatui’s House of the Hearth.

The children housed in this facility were forced to pass through a “pitch-black hearth (a soot-covered chimney)” as a rite of passage. Crawling through the darkness and soot, the children who finally declared “I am dead” experienced a hallucination where the Crimson Moon appeared before them as a giant, terrifying eye. They were then congratulated by the adults, who proclaimed, “You have passed through the fire of two worlds and are reborn.” Arlecchino’s alias, “Cinder of Two Worlds’ Flames,” and the fact that she was raised in the modern House of the Hearth as “Peruere,” indicate that she is the direct successor to this occult ritual and bloodline of ancient Khaenri’ah.

1.3 The Usurpation of the Dynasty and the “Moon-Hunter Sinner” Rerir

However, this era of the Crimson Moon did not last forever. A coup d’état erupted, likely due to some ideological conflict or differences in perspective regarding the approach to The Abyss. The Crimson Moon Dynasty was overthrown, the Eclipse Dynasty newly seized hegemony, and the moon in the sky was replaced by the “Black Sun.”

Following this usurpation, the Crimson Moon bloodline became the target of a thorough purge. Of particular note here is the existence of Rerir, one of The Five Sinners of Khaenri’ah, who bears the alias “Moon-Hunter.” He was originally a secret agent of the Eclipse Dynasty (Rächer of Solnari), tasked with hunting down the remnants of the Crimson Moon bloodline. The madness that seems to blend Rerir’s abyssal power with the remnants of the Crimson Moon speaks to the gruesomeness of the past dynastic transition.

It is logically deduced that the modern Arlecchino (Peruere) is the descendant of survivors who, to escape such a thorough purge and prevent the extinction of their bloodline, entrusted fragments of the Crimson Moon (or its cursed flames) to one another as a failsafe.

2. The Cursed Bloodline: “Balemoon Bloodfire” and the Afterimages of Fate

The power coursing through Arlecchino’s blood, the “Balemoon Bloodfire,” operates on a fundamentally different mechanism from the general elemental powers (blessings from a Vision) in Teyvat. It is a “curse” itself that violates the boundary between life and death, a mixture of the energy of The Abyss and the authority of an ancient goddess.

2.1 The “Afterimages” of Those Burned by the Flames

The sages of the Crimson Moon performed rituals to engrave the light of the Crimson Moon into the foreign orphans. Arlecchino’s power, connected to this bloodline, is a fusion of Sonnet’s lost authority and the energy of The Abyss, and her blood flows through her veins as literal “cursed flames.”

The most terrifying characteristic of these flames, which defines her existence, is their ability to “anchor the ‘Afterimages’ of the people they burn to this world.” While ordinary flames turn matter to ash and return it to nothingness, the Balemoon Bloodfire bridges the gap between life and death, searing fragments of the dead’s souls and remnants of their memories into this world. Her alias, “Two Worlds’ Flames,” originates from this characteristic that connects the world of the living and the world of the dead (or Teyvat and The Abyss).

When Arlecchino draws out too much power or experiences intense emotional turmoil, these flames consume her body from the inside, creeping up as they burn her blood vessels. Then, the afterimages of those she has killed appear as hallucinations, tormenting her mind. She bears the eternal punishment (trauma) of constantly carrying the memories of the lives she has taken, which simultaneously serves as a manifestation of her existential resolve to never look away from her own actions.

2.2 The Ontology of the “X” Pupils and Blackening Limbs

Arlecchino’s visual characteristics—the “cross-shaped (X) red pupils” and “arms gradually dyed in pitch black”—are not mere design choices, but decisive evidence indicating the curse she bears and her cosmological standing.

First, regarding the pupils: while the bloodline of the Eclipse Dynasty (such as Dainsleif and Kaeya) possesses “star-shaped” pupils, the Crimson Moon bloodline has “X (cross-shaped)” pupils. As implied by the name of Arlecchino’s unique weekly boss drop material, “Denial and Judgment,” this “X” symbolizes a “denial” of fate, a “rebellion” against the gods, or a “judgment” upon those who destroyed the former dynasty (Crimson Moon).

Furthermore, as a theory deeply discussed within the lore community, it has been pointed out that this “X” might be connected to the pupils of the Sustainer of Heavenly Principles or the root of life creation (a metaphor for the X chromosome). However, the most logical interpretation at present is that this is a mark signifying “deviation from and rejection of the system of Teyvat’s starry sky (fate).”

Regarding her pitch-black limbs, many researchers have pointed out their visual similarity to those of “Caterpillar,” a hilichurl modified into a sentient humanoid form by the “Narzissenkreuz Ordo” in Fontaine. Considering that hilichurls are the ultimate fate of the curse of The Abyss (or the curse of Khaenri’ah), the blackening of Arlecchino’s body can also be interpreted as a visualization of the process of losing her humanity due to the accumulation of abyssal energy. As she herself fears that “if this corruption reaches my heart, I will transform into something else entirely,” this black corruption is a kind of time bomb, and she constantly lives on the brink of the collapse of her own existence.

3. The Purgatory of the “House of the Hearth”: The Matricide of the Mother and the Birth of the Father

The most personal and decisive turning point that shaped Arlecchino’s philosophy lies in her childhood and her blood-soaked feud with her predecessor, “The Knave” Crucabena. Housed in the Fatui’s House of the Hearth as an orphan bearing the blood of the Crimson Moon, Peruere would experience the deception of a pseudo-family and a cruel struggle for survival there.

3.1 Crucabena’s Deception of Love and the Death Game

The previous Knave, Crucabena, outwardly acted as a compassionate “Mother” to the orphans, but in reality, she was a ruthless tyrant who manipulated the children through absolute domination and brainwashing. Under her rule, the House of the Hearth was a space where death and madness were always side by side, just as her daughter Clervie described it as a “purgatory.”

Crucabena forced the children to kill each other to determine the “King.” Those who were severely injured and rendered useless in this death game were either handed over as test subjects for the human experiments of “The Doctor” (Il Dottore) or sent on suicidal missions from which there was no return. This was an extreme ideology of elitism masked under the guise of “love for the family,” a cruel system that extracted only “useful pawns” and literally ground down the incompetent as cogs (or lubricant) in the massive machine known as the Fatui. It is said that only Peruere and Clervie—who, despite being her biological daughter, hated her mother’s madness—realized the bottomless malice of this “Mother” from the very beginning.

3.2 The Death of Clervie and the Matricide of the Mother

Ten years after Peruere and Clervie met, the two were forced to fight each other to the death due to the cruel rules set by Crucabena. In this duel, Peruere ended up taking the life of her best friend, Clervie, but due to the characteristics of her “Balemoon Bloodfire,” Clervie’s “shade (afterimage)” was absorbed into Peruere. This event created an irreversible existential rift for Peruere. Having imprisoned her best friend’s soul within herself, she resolved to fundamentally destroy the world ruled by Crucabena.

One year later, Peruere finally confronted Crucabena and struck down the “Mother” in the exact same place where Clervie had once fallen. Having committed the grave sin against the Fatui of murdering a Harbinger, Peruere was subjected to a harsh trial in Snezhnaya. However, through the intervention of the Director of the Fatui, “Pierro,” she succeeded in securing a pardon from The Tsaritsa.

As a fellow survivor of Khaenri’ah, Pierro recognized the value of the Crimson Moon bloodline dormant within her. In a closed room, he revealed to Peruere that she was a descendant of the Crimson Moon Dynasty, which was thought to be extinct, and urged her to read the book Perinheri as a clue to discovering her roots. Thus, Peruere assumed total control of the House of the Hearth as the new Fourth of the Fatui Harbingers, “The Knave” (Arlecchino).

4. The Philosophy of the “Father”: The Spider’s Web and the Illusion of Family

While Crucabena exploited the children by feigning “love” and “motherhood,” Arlecchino deliberately adopted the title of a cold and strict “Father,” choosing to rule through fear and discipline. This paradigm shift is the most crucial element in understanding her philosophy.

4.1 The Spider’s Thread and Protection Through Fear

At first glance, Arlecchino’s rule appears even more despotic and tyrannical than her predecessor’s. However, its essence is the construction of a “sturdy fortress to unconditionally protect the children from a cruel world.” In her philosophy, for orphans with no blood ties to survive in the harsh world of Teyvat, overwhelming power and genuine bonds (absolute loyalty) were necessary.

The motif of a “Spider” is intentionally scattered throughout the powers she wields and the adornments on her clothing. The text for the material “Silken Feather,” dropped by her as a weekly boss, reads as follows:

“To answer the wishes of young children seeking the protection of a parent bird’s wings, ‘Father’ wove dangerous spider silk into the shape of feathers, providing warmth to the family.”

Spider silk is a cruel trap to catch external prey, but at the same time, it is an extremely resilient barrier to protect one’s own territory (the family’s sanctuary) from outside enemies. Arlecchino’s love, like a blood-stained spider’s web, is eerie and unapproachable, yet thoroughly self-sacrificing and protective toward those within it.

4.2 The “Flames of Memory” and True Freedom

She enforces an absolute rule where betrayal is punishable by death, but this does not stem from sadism like Crucabena’s. In fact, for those who wish to leave the House of the Hearth, she provides a path to “true freedom” by having them drink a special memory-wiping potion (Bottled Flame) made using her “Balemoon Bloodfire,” which erases all memories related to the House of the Hearth and the Fatui, allowing them to return to normal society.

Erasing their memories is synonymous with “killing” their former identities once. However, it is simultaneously a means to completely liberate them from the curse of Snezhnaya and the blood-stained fate of being Fatui operatives. Arlecchino understands more deeply than anyone that the concept of “family” is nothing more than an “Illusion” formed by those who originally have no blood ties gathering together. Yet, she also knows that this very illusion is the only “Hearth” that allows the lonely ones (the descendants of drifters from the Sea of Stars) to maintain their sanity in the cold universe of Teyvat.

Her actions during the crisis of the prophecy, where Fontaine was to be submerged by the waters of the Primordial Sea, vividly illustrate this philosophy. Despite having the supreme directive from The Tsaritsa to obtain the Gnosis, she negotiated on equal terms with the Hydro Archon Furina and the Iudex Neuvillette, sparing no physical or informational support to save Fontaine, where her “children” (Lyney, Lynette, Freminet, and others) live. Her top priority is always to protect the “illusion of family,” and for that sake, she showed the will to directly oppose even the prophecy decreed by The Heavenly Principles.

5. Alchemy and Gnosticism: The Flames of Purification and the Subversion of Commedia

Arlecchino’s behavioral principles and worldview are intricately intertwined with the Gnosticism themes and alchemical contexts that flow at the foundation of Genshin Impact’s story, as well as the meta-interpretation of the “Commedia dell’arte,” which serves as the motif for the Fatui.

5.1 The Culmination of Alchemy: “Rubedo (Reddening)”

Arlecchino’s story clearly embodies the process of “Rubedo (Reddening),” the final stage of the Magnum Opus in medieval alchemy. The general alchemical process proceeds in the order of Nigredo (blackening/putrefaction) → Albedo (whitening/purification) → Citrinitas (yellowing/awakening) → Rubedo (reddening/completion of the Philosopher’s Stone).

In the history of Teyvat, the creations of the Khaenri’ahn alchemist “Gold” Rhinedottir are deeply connected to this process. These include the evil dragon Durin (Nigredo), representing the pitch-black of “Humus,” and Albedo, representing “Chalk.” Although there is no evidence that Arlecchino herself is a direct creation of Rhinedottir, inheriting Khaenri’ah’s “blood of the Crimson Moon” and the “Balemoon Bloodfire,” she is the very symbol of “Rubedo.” All of her abilities are concentrated in “blood” and “red flames,” which are the energies of destruction and rebirth meant to incinerate imperfect matter (fate) and reach a state of perfect existence (the Philosopher’s Stone).

5.2 “Ignis Purgatorius” and Gnostic Free Will

Her Constellation, “Ignis Purgatorius,” means “Flames of Purification” in Latin. In Catholic doctrine, the fire of Purgatory is a fire that burns away the sins of the soul, performing a purification to ascend to Heaven. The fact that the House of the Hearth ruled by Crucabena was called a “purgatory” and that Arlecchino’s Constellation is “Ignis Purgatorius (Fire of Purgatory)” forms a brilliant poetic contrast. While her predecessor was the lord of purgatory who inflicted sin and pain upon the children, Arlecchino takes that sin (curse) upon herself, functioning as the “flames of purification” that incinerate the old world to transmute a new world (a true family).

The central concepts in her combat mechanics, “Bond of Life” and “Blood-Debt Directive,” are also metaphors for the “exercise of free will” in Gnosticism. The “Bond of Life” is the act of borrowing one’s own life (healing effects) in advance as a debt, converting it into physical power (a scythe of fire). From the perspective of Gnosticism, the humans of Teyvat are prisoners of the material world of a false god (Demiurge = The Heavenly Principles), destined to live according to the dictates of the “Loom of Fate” and Irminsul. Arlecchino rejects the web of fate decreed by the starry sky (The Heavenly Principles) and exercises her “free will,” even if it means burning her own life borrowed in advance.

The words spoken about her by the Director, “Pierro,” succinctly express this existential struggle:

“Fate grants favors to no one. Only those who would fight it with every ounce of their being may earn the right to challenge it”

5.3 The Archetypes of Commedia dell’arte and Their Subversion

Furthermore, indispensable to her character design is the intentional subversion of the archetypes from the Italian improvisational comedy, “Commedia dell’arte.”

In Commedia dell’arte, “Arlecchino (Harlequin)” is depicted as a nimble clown wearing diamond-patterned clothes, possessing high physical ability but lacking intelligence, often serving as a comic relief who makes ludicrous blunders. He is also frequently cast in the role of a lover yearning for “Columbina,” a fellow servant character.

However, Arlecchino in Genshin Impact completely “subverts” this classical archetype. Far from being a clown, she possesses the most strict and cold rationality among the Harbingers, acting as a dignified “Father” devoid of emotion. In stark contrast to the Commedia’s Arlecchino, who is never taken seriously by the audience, the Arlecchino of Teyvat reigns as an existentialist who faces her blood-stained fate head-on and allows absolutely no compromise.

This intentional “subversion of roles” can be said to meta-textually express that the Fatui as an entire organization is a gathering of those who seek to destroy the “script of the stage known as Teyvat (fate)” given by the false gods (The Heavenly Principles). It is a manifestation of the will of one destined to play the “foolish clown” in the script of fate, who tears up that script by her own will and attempts to incinerate the stage itself.

6. The Latest Historical Revelations: Columbina and the Defeat of the “False Moon God”

In the latest abyssal lore (Luna I–III) as of 2026, the myth of the Crimson Moon shows further developments. This chapter supplements the mythological conclusions revealed by the latest Archon Quests and artifacts.

It is suggested that the goddess Sonnet, who once fused with The Abyss and became the Crimson Moon, had an older sister, the eternal moon Aria, and a younger sister belonging to the Frost Moon, Columbina. In the latest story, Columbina is reborn in Teyvat as the “Trilune Goddess” and confronts the rampage of the Second Harbinger, “The Doctor” (Il Dottore).

Il Dottore attempted to ascend to a “False Moon God” by combining the artificial marrow he created with the authorities of Columbina and the Iridescent Moon (Crimson Moon). However, through the cooperation of the Traveler, various factions of Nod-Krai, and the reborn Columbina, he is defeated. At the end of this fierce struggle, Columbina recovered the “Iridescent Moon’s marrow” left behind by her sister Sonnet and returned it to Arlecchino, the rightful heir of the bloodline.

“From this day forth, may the Two Worlds’ Flames burn ever more brightly.”

Through this mythological ritual, Arlecchino completely inherited the true power of the Crimson Moon, paving the way to bring even the cursed energy that had been consuming her under complete control. Her existence was elevated from a mere relic of Khaenri’ah to an “observer of mythological dimensions” capable of reconstructing the very cosmology of Teyvat.

Conclusion: The “Fire of Purgatory” That Incinerates the Old World and Transmutes the New

The entity known as “The Knave” Arlecchino (Peruere) is a living recording medium of Teyvat’s hidden history and mythology. The “blood of the Crimson Moon” flowing through her veins is a remnant of ancient Khaenri’ah’s ambition to seek a Descender who transcends the gods, and the “Balemoon Bloodfire” residing in her hands is nothing less than a singularity connecting life and death, as well as the past and the future.

To summarize her philosophy, it is an “intense and self-sacrificing antithesis to fatalistic determinism.” While her predecessor Crucabena exploited the children according to the Laws of the world (survival of the fittest), Arlecchino took on the title of “Father” herself and wove a spider’s web (House of the Hearth) to isolate the children from a cruel world. She coldly anticipates the day when the blood curse flowing within her will consume her heart, leading to the complete loss of her self. Even so, she refuses to yield to fate, continuing to purify her own soul and the world with the hellfire (Ignis Purgatorius) that borrows life in advance.

“Someday, the hearth-fire’s faint radiance shall burn the old world away”

This single sentence, engraved in her archive as a weekly boss, summarizes her ultimate thesis. She belongs neither to the script of history woven into Irminsul nor to the “False Sky” decreed by The Heavenly Principles. Feeding her own sins and madness into the firewood, Arlecchino continues to quietly burn the flames toward the end of the world (the transmutation of a new world) all alone, in order to protect the fragile yet beautiful illusion of family. Her very existence is the most beautiful and cruel “fire of purgatory” itself, destined to burn the god named fate to death.
