Nyxtharion #2

Nyxtharion #2 is a numbered wall-guardian fragment of the Elder Dragon Nyxtharion the Evernight. Created from part of the original dragon's brain, he is the most analytical of the early fragments and becomes Neo Hargraves's mentor in True Void, created energy, and Heavenbreaker Cosmos development. He later separates from the shared hivemind, survives inside Neo's Cosmos, and trains Jack Hanma for centuries.

Nyxtharion #2 is not the original dragon, Nyxtharion #4, or Zero. The numbered wall guardians share memories and call themselves the Great I, but occupy distinct pieces with different functions and decisions. Zero is a later, palm-sized dragon created from part of #2's soul; he accompanies Jack while #2 remains on Luminera and communicates with him telepathically.

Biography

Brain-piece strategist in the Tartarus hivemind

Nyxtharion #2 enters the Abyss of Nightmares as one of the wall guardians defending Layer 4 for Tartarus. When Neo repeatedly attacks and regresses, #2 identifies the pattern: Neo hides the signs of time travel, copies the dragons' techniques, and uses each interval of ignorance to improve. Unlike #4, #2 understands that returning to the timeline's starting point will not erase Neo's accumulated awareness. The narration attributes that reasoning to his origin in a piece of the original dragon's brain. (Chapter 486)

He helps coordinate Infinite Void Prison and orders the hivemind to interrogate Neo when the Heavenbreaker abruptly claims to be their ally against Jack. #2 reads the absence of bloodlust as evidence that the claim deserves testing, even though the dragons remember earlier attacks. A twisted-timeline event then leaves Neo believing fabricated memories of service to Kane, and Neo opens those memories to the hivemind as proof. #2 becomes the principal advocate for interpreting them as genuine. (Chapters 487–488)

His conclusion is intelligent and completely wrong. Neo's false history says he must devour the Zone Protectors, an act that should destroy the Nightmare's Pillars. #2 reasons that Neo's Darkness will also absorb Tartarus's fragments, turning an immortal Heavenbreaker into a replacement Pillar and preserving the Layer against Jack. The other guardians vote to test the hypothesis, revive Zone 2's Protector, and kill it so Neo can take its power. #2's analysis thereby converts an enemy's deception into a structured alliance. (Chapters 488–490)

The shared title “Great I” does not eliminate the pieces' differences. #2 can snap at #4, lead votes, conceal thoughts, and later betray the original collective, while the other numbers contribute their own powers and opinions. Their hivemind supplies common memory and communication rather than one physically indivisible speaker. This distinction becomes decisive once #2 is moved beyond the connection and continues to live after the central fragment is devoured. (Chapters 486–490 and 519–520)

True Void and Heavenbreaker mentor

Devouring the Protector gives Neo enormous Shadow power and equally enormous madness. #2 joins the other guardians in drawing that madness into the hivemind, warns that they cannot survive doing so again, and refuses Neo's plan to consume another Protector immediately. Instead, he prescribes training until Neo can control the arsenal already acquired. That restraint makes #2 more than an unwitting supplier: he becomes the mentor who recognizes that power without refinement will destroy the intended champion. (Chapter 491)

The curriculum begins with Voidfang Rain and Space Lock, then expands into True Void. #2 explains that Void can return things to null or force uncontrolled evolution, and that corruption of body, soul, or both carries increasingly catastrophic consequences. He situates those dangers within wider divine development: Gods refine elements, Void Gods accelerate the creation of new energy types, and Heavenbreakers build through a World Core and an internal World rather than following an inherited elemental road. (Chapters 492–494)

Nyxtharion #2 guides Neo to access the internal space around his World Core and insists that “Cosmos” is more accurate than “World.” He teaches Neo to mark territory with World Energy, move Obitus inside, and apply Void to the energy powering Death Sword. The experiment produces Death Sword Firmament, a self-sustaining energy with Consciousness. #2 identifies that creation from nothing as the defining power that places Heavenbreakers beyond ordinary Gods. (Chapters 495–497)

The mentorship also restores Neo's agency. #2 notices memories sealed within the sea of madness, promises to conceal them from the wider hivemind, and tells Neo to recover them. Later, when Neo's information Trait begins giving more detailed answers, #2 explains the Sea of All Consciousness and how proper First-Step Ascension improves a Heavenbreaker's access to it. His teaching connects Neo's seemingly unrelated Traits, Intent, Firmaments, and Cosmos into one coherent model of advancement. (Chapters 497 and 505)

Defection, moral uncertainty, and separation from the Great I

After Neo regains his memories, #2 asks him to defeat the original I and privately wonders whether the worlds condemned by Nyxtharion and Tartarus deserved their punishment. He continues clearing a path for Neo even when the Heavenbreaker begins devouring entire Zones rather than merely taking Protectors. The decision makes him a traitor to his own shared selves. Neo recognizes that #1 will kill #2 once the hivemind understands the betrayal and delays the confrontation until he can protect the mentor. (Chapters 497 and 500)

The dependence on #1 makes that danger existential. Nyxtharion #1's necromancy has revived numbered pieces #2 through #537, and the narration expects those pieces to die if the sustaining necromancer is destroyed. #2 is also born from the original's brain rather than being a complete reincarnation of the ancient dragon. He carries insight and shared memory, but not the full original body, history, or unbroken independent life. (Chapter 500)

Before attacking #1, Neo approaches #2 through the Intent clone known as Thanatos. The dragon asks whether his service delivered justice or only a madman's judgment and expects to die without an answer. Neo refuses to serve as god or avenger and instead offers another life in which #2 can meet the people he condemned. He sends the dragon into his Cosmos, where the cross-Cosmos distance immediately cuts the hivemind connection. (Chapter 519)

Celestra shows #2 the merged lands and resurrected populations of the Zones. He recognizes former monsters, Protectors, and expedition members and asks permission to speak with them. Only after this separation does Neo confront and devour #1. Nyxtharion #2 therefore survives not because he becomes #1, but because Neo removes the numbered piece from the system that would otherwise tie his existence to the original necromancer's destruction. (Chapters 519–520)

Erased past, planetary guardian, and Jack's mentor

The Eternals later erase the Tartarus history from both Nyxtharion #2 and the people of the Zones. They no longer remember one another, and the dragon loses the moral inquiry Neo preserved him to pursue. In the replacement memory, Neo saved #2 at death's door and #2 pledged loyalty to him. He consequently addresses Neo as Godfather with sincere devotion, a relationship produced by altered memory rather than a recovered account of their difficult alliance. (Chapter 541)

Neo brings him out of the Cosmos, and #2 reduces his body to a black dragon smaller than Neo's palm. Ordered to protect Earth, he surveys the continent and immediately asks to train Jack. Neo grants permission and later tells #2 to pressure Jack if necessary. The dragon is disturbed by Neo's deliberately scandalous description of Jack but still goes to begin the tutelage, shifting from Neo's teacher to the teacher of Neo's closest friend. (Chapters 541 and 543)

Over the next five hundred years, Jack travels the universe under Nyxtharion #2's instruction and returns to Earth between invasions. The dragon also forms Zero from a piece of his soul. Zero has his own body, dialogue, and judgments while accompanying Jack at the Solar System barrier; meanwhile, #2 remains on Luminera and sends Zero telepathic information. The simultaneous locations make the distinction explicit: Zero is a soul offshoot and student-companion, not a renamed or transformed Nyxtharion #2. (Chapter 571)

The last direct state shown for #2 is therefore active guardianship under the rewritten history. He is separate from the dead or devoured original fragments, separate from #4, and separate from Zero, but no longer remembers why Neo first rescued him. Jack's advanced necromantic development and ability to defend Earth become the durable result of his teaching, even though the mentor himself has lost the moral and historical context of that relationship. (Chapters 541–543 and 571)

Appearance and personality

Nyxtharion #2 first appears as a wall-guardian dragon piece within the underground Zones of Tartarus. Void has changed his body, and his dragon form is marked by the corruption he explains to Neo. After the Eternals rewrite memory, he can morph into a tiny black dragon smaller than Neo's palm, showing that the later companion-sized body is a chosen reduction rather than proof that he has become Zero. (Chapters 493 and 541)

He is analytical, proud, and initially speaks through the collective grammar of “the Great I.” His brain-piece origin gives him confidence in deductions that can become comic overconfidence when Neo feeds him false premises. Teaching moderates that pride. He apologizes, treats Neo as an equal, questions the justice he once served, and accepts death rather than return to thoughtless obedience. Altered memory later replaces that hard-won doubt with uncomplicated loyalty, making his final devotion sincere but historically manufactured. (Chapters 486–500, 519, and 541)

Powers and limitations

Hivemind, strategy, and collective techniques

Nyxtharion #2 shares a hivemind with the other fragments of Nyxtharion the Evernight. The network exchanges memories, emotions, votes, sensory information, and power; it can also admit Neo or block him. Through collective action the wall guardians activate Infinite Void Prison, revive Zone Protectors, regress time, and absorb part of Neo's madness. #2's brain-derived reasoning makes him a strategist within that network, not its sole controller. (Chapters 486–491)

The hivemind has severe limits. Neo can fabricate memories with Intent, exploit time-loop delays, and hide recovered thoughts when #2 assists him. Cross-Cosmos separation breaks the connection entirely, individual guardians can dissent, and the larger collective eventually identifies #2 as a traitor. Their shared name does not prevent conflicting decisions or guarantee that information is true; it merely makes one mistaken deduction propagate quickly through many bodies. (Chapters 487–500 and 519)

Void, space, and divine instruction

Nyxtharion #2 wields and teaches Void and Space techniques, including Voidfang Rain, Space Lock, and the principles behind Infinite Void Prison. He understands bodily and soul corruption, forced energy evolution, elemental God paths, World Cores, First-Step Ascension, Firmaments, and the Sea of All Consciousness. His greatest demonstrated contribution is instructional: Neo uses this knowledge to create new conscious energies and stabilize an independent Heavenbreaker Path. (Chapters 486 and 492–505)

The corpus never gives #2 a personal Stage, Grade, or level. Descriptions of Protectors, Neo's progression, Stage 3 worlds, and the collective Elder Dragon must not be substituted for his rank. He is powerful enough to analyze a continent at a glance and train Jack across the universe, but those feats remain unnumbered. The absence of a public progression table reflects missing explicit attainment, not an assumption that he lacks power. (Chapters 490–505, 541, and 571)

Fragment existence, resurrection, and soul division

Nyxtharion #2 originates from part of the ancient dragon's brain and is revived through #1's necromancy. Ordinarily, destroying #1 would end all the dependent pieces. Neo avoids that result by moving #2 into another Cosmos before devouring the sustaining fragment. The survival establishes individual continuity for #2 after separation, but it does not restore the complete original Nyxtharion or transfer every other numbered identity into him. (Chapters 486, 500, and 519–520)

He can later divide part of his own soul to create Zero. Zero remains telepathically connected but acts independently beside Jack while #2 stays on Luminera. This resembles descent or offshoot creation more than a bodily disguise: #2 already possesses a separate palm-sized form in Chapter 541, yet Chapter 571 places that continuing dragon and Zero in different locations. Neither should be conflated with Nyxtharion #4 or the original #1. (Chapters 541 and 571)

Relationships

Neo Hargraves

Neo first deceives #2 with altered memories, but the relationship grows beyond the lie through instruction and shared doubt. #2 enables Neo's True Void and Cosmos breakthroughs and asks him for an honest judgment on the Great I's history. Neo refuses to dictate the answer, saves him from #1, and creates the conditions for independent reflection. The Eternals then erase that history, leaving #2 loyal to Neo as Godfather without remembering the manipulation, mentorship, or moral promise that preceded the title. (Chapters 487–505, 519–520, and 541)

Jack Hanma and Zero

Nyxtharion #2 chooses Jack as a student on sight and trains him across the universe for five hundred years. That tutelage follows Neo's permission but becomes a sustained relationship visible in Jack's later strength and travel. Zero, created from part of #2's soul, serves as the mentor's mobile presence beside Jack while retaining independent speech. Telepathy between Zero and #2 allows guidance across distance without making the two dragons one body. (Chapters 541, 543, and 571)

Nyxtharion #1, #4, and the Great I

#1 is the necromantic fragment sustaining hundreds of revived pieces; #4 is another wall guardian with a more impulsive disposition; #2 is the brain-derived strategist among them. They share the Great I's hivemind and often speak as extensions of one Elder Dragon, yet vote, disagree, conceal information, and face different fates. #2's defection and survival prove that shared origin and networked consciousness do not erase numbered identity. (Chapters 486–500 and 519–520)

Celestra and the people of the Zones

Celestra receives #2 after Neo transfers him into the Cosmos and explains that distance from the former universe has cut the hivemind. She then shows him the people whose worlds he guarded as prisons. His request to speak with them is the first concrete step toward answering whether the Great I served justice. The later memory erasure prevents that inquiry from reaching a known conclusion, leaving Celestra as witness to a rehabilitation #2 himself can no longer remember. (Chapters 519 and 541)

Items

Nyxtharion #2 is not consistently associated with a personal artifact. Infinite Void Prison, Space Lock, Voidfang Rain, the hivemind, and his morphing body are techniques or inherent fragment abilities rather than carried equipment. Zero is likewise a soul-derived person, not an item in #2's possession. (Chapters 486–493 and 571)
