Little Butterfly — Diary of a Dead Wizard

Little Butterfly is the Nightmare Butterfly that hatches through Saul's dream and becomes a silver bookmark in the Dead Wizard's Diary. Saul later calls her “Penny,” but she is not the original Penny: the intended rebirth loses part of its inherited history while observing Saul, and the new butterfly explicitly identifies herself as a different self. She grows into Saul's dream scout, emotional observer, and long-lived traveling companion. (Chapters 330–332 and 1037)

Biography

A failed rebirth and a chosen name

The Nightmare Butterfly cocoon vanishes after Saul collapses during an experiment, and the attempted rebirth unfolds inside his dream. The predecessor's consciousness intends to transfer its history into a new body while drawing strength from Saul's past, but Saul's cross-world history proves dangerously alien. The observer is injured, loses part of the history that should have preserved continuity, and emerges in the diary as a hollow silver butterfly bookmark. When Saul asks whether she is Penny, she answers directly that she was supposed to be, but no longer is. (Chapters 330–331)

Saul learns that Nightmare Butterfly eggs are rebirth vessels rather than offspring, yet the new butterfly's lost history makes the result discontinuous from the original individual. He nevertheless proposes “Penny” as a convenient name, and she happily accepts it; his later use of that name reflects their bond, not proof that the original Penny survived unchanged. Little Butterfly initially claims she has lost all useful powers, but stray knowledge of Saul's mental techniques exposes that she retained fragments and concealed them for safety. Saul allows her to remain outside the diary under limits, beginning a relationship shaped by cautious ownership, negotiated freedom, and her desire to prove her value. (Chapters 332–333 and 349)

Veiled essence and the Elf Valley

Little Butterfly immediately recognizes Veiled Crystal Essence as a liminal material like herself and begs Saul to let her consume it, explaining how flesh and conscious recognition are needed to keep it from being lost. The essence restores enough strength for her to act as more than a mascot. She helps Saul identify the route into Elf Valley, sustains dream work around Hayden, and guides him through a place where perception, desire, and memory are more dangerous than ordinary walls. Her knowledge is incomplete, but it repeatedly turns strange mental phenomena into choices Saul can understand. (Chapters 349, 354, and 373–375)

Inside the Elf King's palace, she sees forms differently from Saul, interprets the spiritual world's signals, and warns him when the twisted staircase appears. She explains that the valley's inhabitants are imprisoned by their own desires and reveals fragments of how the Elven King helped condemn the race after observing the world's sinkhole. When alien consciousnesses try to rewrite Saul's sense of the past, Little Butterfly is herself influenced and fails to recognize the danger in time, showing that her affinity for dreams does not make her immune to higher mental forces. Saul returns her to the diary until the threat passes, preserving both of them. (Chapters 383–385)

Scout after the tower's fall

Little Butterfly leaves the collapsing Gorsa Wizard Tower with Saul, Little Algae, the diary, and its resident consciousnesses. In the uncertain journey that follows, her abilities become operational tools: she scatters dream phosphorus to mark targets, detects active dreams where normal scouting finds no survivors, enters damaged minds, hides Saul's aura, and helps him escape inverted dream structures before their exits collapse. These tasks make her especially valuable against enemies who can evade ordinary senses, while her chatter keeps the diary household socially connected during displacement. (Chapters 437–439, 443–452, 487, and 499)

Her usefulness also exposes sharper limits. Dream Bell effects, star-linked visions, Clark, and other high-order dream phenomena frighten or overpower her; Saul must distinguish between a warning from an expert and panic from a vulnerable young being. Clark's demand that Saul hand her over proves that Nightmare Butterfly abilities are coveted by far stronger wizards. Saul refuses to treat her as expendable even when surrender might buy temporary safety, and the promised possibility of future independence gradually makes her loyalty more voluntary than the bookmark's binding alone. (Chapters 530–541, 606–631, and 699)

Continental investigations and wars

As Saul's reach expands, Little Butterfly becomes a precise infiltration and interrogation partner. In ruined Caugust she makes watching apprentices forget their purpose, locates surviving dreams, expands into dream wings to carry Saul through Jonah's mind, and briefly drops Bethstana into sleep so Herman can seize the Inverted Tree seed. In Sky City and Nephret she hypnotizes obstacles, reads emotional shifts invisible to Saul, creates nightmares based on the Prismatic World, and advises him during political and experimental danger. Her comments can be predatory and flippant, but her observations often supply the small discrepancy that exposes a lie or hidden intention. (Chapters 715–723, 765, 782–787, and 824–846)

Late in the conflict, Little Butterfly's older gift of historical observation returns in a more capable form. At the First Wizard Tower she reconstructs a burned letter and the scene of Corey destroying it, revealing the red worm concealed above Corey's head and clarifying how the tower has been compromised. Saul praises the result but stops her from probing an unknown worm directly, recognizing that her curiosity could again destroy the history supporting her selfhood. She continues as scout, dream detector, and emotional monitor during the red-worm crisis and Saul's full transformation into a Fourth Rank Wizard. (Chapters 927–928, 951–952, 965–992)

Beyond the wizard world

Little Butterfly remains beside Saul when the final crises force him to operate through fate lines, prophetic dreams, and world-scale structures that exceed her ability to inspect safely. She patrols rooms, watches suspects, comforts angry companions, and celebrates Saul's Fourth Rank transformation with characteristic bravado. Her power is no longer decisive against the highest beings, but Saul continues to value her as a witness and companion rather than only a tool, and she identifies herself with the wider diary household when one of its members is harmed. (Chapters 970, 976, 979–981, and 991–1001)

When the Death Demon removes Saul from the wizard world, only Little Butterfly and Little Algae remain hidden with him. Across a long journey among stars and other worlds, her talk and Little Algae's familiar sounds keep Saul from being alone. She later watches him search distant lives and finally follows when he senses a path back to the Purity Wizard Tower. Her continued presence at the ending confirms both her survival and the permanence of the new identity formed after the failed rebirth: she is Saul's “Penny,” but not a retroactive continuation of the girl who died at Grind Sail. (Chapter 1037)

Appearance and personality

Little Butterfly usually appears as a silver, metal-like butterfly with hollow-carved wings, identical to the bookmark embedded in the diary. At first she can be seen by Saul and Little Algae but cannot be physically touched, and her voice resembles that of a four- or five-year-old child. In dreams she can take a little girl's form with silver irises made from countless hexagonal eyes, or spread enormous silver wings behind Saul. As her strength and material support increase, she can interact more directly with dream environments while retaining the small butterfly form in waking life. (Chapters 330–332, 354, 385, and 717–718)

She is curious, theatrical, talkative, and quick to mock danger once she feels protected. Her cheerful address of “Brother Saul” coexists with inherited Nightmare Butterfly instincts: she sometimes evaluates people as edible mental resources, takes pleasure in frightening enemies, and treats strangers' suffering as entertainment. Yet she is also cautious about confinement, protective of Saul and the diary household, and capable of indignation when companions are abused. Her concealed abilities and gradual disclosures reflect self-preservation after hatching, while her later candor shows that trust has replaced much of that fear. (Chapters 331–333, 349, 717–723, 783–787, and 976)

Abilities

Dreams, hypnosis, and nightmares

Little Butterfly can sense active dreams, enter or link sleepers' dreamscapes, and bring Saul or other participants into those environments. Her enlarged dream wings help navigate collapsing dream structures, while direct contact can impose sleep or trap an enemy in a tailored nightmare. She can also keep a dream continuing long enough for research or communication. These powers are strongest against vulnerable minds and can fail quickly against powerful wizards, alien mental structures, or targets that awaken before she can withdraw safely. (Chapters 354, 443–452, 487–499, 717–723, and 783–787)

Tracking and concealment

Dream phosphorus lets Little Butterfly mark a target through mental traces and pursue individuals who evade ordinary magical perception. She can hide Saul's aura, disrupt observers' intentions, detect concealed survivors by their dreams, and monitor emotional changes during negotiations or experiments. These abilities make her a recurring counter to stealth and deception, though they require attention: she sometimes becomes distracted by spectacle and admits when she failed to watch the relevant person. (Chapters 443–452, 499, 715–723, 951, and 979–981)

Historical observation

Nightmare Butterflies stabilize themselves through “history” and can observe past events attached to people or objects. Little Butterfly initially loses most of that inheritance and downplays what remains, but later reconstructs burned paper into a visible historical scene and identifies details no ordinary witness can recover. Looking too deeply is dangerous. Saul's cross-world history damages her rebirth, the Elf world's consciousness influences her, and unknown high-level beings may contaminate or erase the observer; Saul therefore restricts historical probes when the target's nature is unclear. (Chapters 330–333, 383–385, and 927–928)

Liminal existence

Little Butterfly exists between physical life and consciousness. The diary houses her as a bookmark rather than a soul page, allowing her to appear outside it, pass through ordinary attacks, and return instantly when threatened. Veiled Crystal Essence strengthens this unusual state, while her own remembered history helps affirm and repair her identity. The same condition creates vulnerabilities: powerful dream or star phenomena can reach her directly, and the diary's control can flatten her back into the bookmark if Saul judges her actions unsafe. (Chapters 331–332, 349, 354, 385, and 606–631)

Items

Dead Wizard's Diary: Little Butterfly first emerges as a silver bookmark at the diary's back cover. The artifact gives Saul the means to house, recall, and restrain her, but it also protects the unstable post-hatching self and provides the household in which she forms new relationships. (Chapters 331–333 and 437–439)
Veiled Crystal Essence: Little Butterfly recognizes the essence as a substance sharing her boundary between matter and consciousness. She teaches Saul how it must be preserved and consumes it to restore enough strength for later dream work. (Chapters 349 and 354)

Relationships

Saul: Saul's dangerous history disrupts her intended rebirth, but he also protects the new self that results. He names her Penny, binds her through the diary, sets limits on dream entry, and gradually treats her as a trusted scout whose life cannot be casually spent. She answers with practical intelligence, constant teasing, and loyalty that persists even after they leave the wizard world. (Chapters 330–333, 349, 443–499, 606–631, 699, and 1037)
Penny: The original Penny is Little Butterfly's predecessor, not an interchangeable treatment identity. The rebirth was meant to carry Penny's consciousness and history into the egg, but the encounter with Saul's past destroys part of that continuity. Little Butterfly explicitly says she is not Penny; she later accepts the same name from Saul and inherits fragments and species instincts, creating a successor relationship rather than undoing the original Penny's death. (Chapters 330–332)
Little Algae: Little Algae can perceive Little Butterfly when ordinary physical senses cannot. Their early interactions are a teasing rivalry of ambushes, tongues, and evasions, but they become Saul's two persistent nonhuman companions. Both remain hidden with him when the Death Demon carries him beyond the wizard world. (Chapters 331–333 and 1037)
Herman: Herman and Little Butterfly frequently scout, search, and fight as members of Saul's diary household. At Caugust she opens a one-breath sleep window that lets him steal the Inverted Tree seed, demonstrating their complementary use of dream control and physical action. (Chapters 715–723)
Agu: Although Little Butterfly is not especially close to the diary consciousnesses, she considers them part of her own group. When Agu is harmed, she becomes indignant and offers to create a punishing nightmare for the responsible wizard. (Chapter 976)
Clark: Clark's dream power terrifies Little Butterfly and makes her a coveted target. He tries to claim her from Saul, while Saul's refusal to surrender her without protection marks an important shift from treating the bookmark as property to treating the being inside it as a companion. (Chapters 530–541 and 606–631)
