Power Progression

Background

Severus grew up in Cokeworth as the son of the witch Eileen Prince and the Muggle Tobias Snape. His childhood home was marked by poverty, Tobias's drinking, and hostility toward the magic shared by Eileen and Severus. Tobias called them “monsters” after seeing Eileen light a fire with magic, leaving Severus confused about why his father resented something he had known about before marriage. 2 3 48

His friendship with Manus developed through their mothers, who had been classmates. Although their homes were separated by almost half of Cokeworth, Severus regularly visited the King household, where Aivina welcomed and fed him. At his first appearance, he crosses the town in heavy snow to spend time with Manus, whose home provides a contrast to his own troubled household. 1

Manus became Severus's first close friend and a refuge from the Snape household. He encouraged Severus to visit whenever conditions at home became unbearable, framing the support as mutual friendship rather than charity. 5 Severus internalized Manus's promise that gaining magical ability, education, and financial independence would allow him to change his family's future. 5 53

After Severus underwent his magical outburst, Eileen began teaching him Potions alongside Manus. Manus also deliberately trained Severus in rational thinking, emotional resilience, and basic pre-wand spellcasting. By age nine, Severus had become markedly more confident, independent, and analytical. 18 54

Manus's influence also altered the Snape household. Eileen recognized that she could resist Tobias rather than remain trapped by habit, substantially improving her and Severus's quality of life while Tobias's influence over them diminished. 60

Severus's wish to join Slytherin was closely connected to Eileen's school history and his desire to honor the Prince family name. Manus reassured him that a strong personal preference would likely influence the Sorting Hat, and Severus subsequently entered his chosen House. 69 70 86

Personality

Severus was initially shy, gentle, and deeply affected by his home environment. He struggled to understand his parents' relationship and blamed himself for hardships he could not control. 3 54 148 Learning about Eileen's lively youth left him troubled by the possibility that she had sacrificed her happiness for him, but he transformed that guilt into a determination to give her financial security and the freedom to choose her own future. 147 148

Despite his ambition, his deepest longing is emotional rather than professional. When Manus allows him to look into the Magic Mirror, Severus sees himself with his parents as a happy family, their appearances and demeanor differing from those he remembers. Lily recognizes the significance of the vision and encourages him to believe that his wish can come true. 112

He is highly ambitious and refuses to accept inferiority as permanent. After recognizing the gulf between himself and Manus, he resolves not merely to catch up, but to create his own path and eventually surpass him. 79 This ambition is paired with pragmatism: he carefully plans for a career in Potions while preserving alternatives through subjects such as Arithmancy and Ancient Runes. 353 354

Severus is sarcastic, competitive, and willing to endure discomfort for growth. He frequently spars with Lily, but their rivalry is grounded in mutual trust; he accepts punishment when he believes he has wronged her and reacts fiercely when others insult or threaten her. 68 352 He rejects Pure-blood extremism despite his Slytherin affiliation, recognizing that the faction would despise him as a Half-blood as readily as it despises Lily. 234 352

His experience with demanding instruction also produces severe expectations of others. After a Potions examination, he criticizes classmates who became nervous under Slughorn's scrutiny and suggests that, as a professor, he would deliberately stand near weaker students during lessons to strengthen their mental resilience. Lily objects to this proposed teaching method. 403

Although emotionally resilient against ordinary bullying, Severus remains burdened by concerns about survival and family responsibility. When Manus frees his Saturdays from their usual training schedule, he initially celebrates and wants to share the news with Lily, but thoughts of the Death Eaters and his mother soon make leisure feel irresponsible. He returns to studying rather than enjoying the entire day off. 483

Greater independence later exposes a different uncertainty. Without Manus's strict timetable, Severus struggles to decide which research deserves his time, weighs profitable Beauty Potions against stalled spell development, and recognizes that choosing his own future is harder than following instructions. Manus regards this confusion as a sign that Severus is genuinely thinking for himself. 520

Abilities & Skills

Potions

Severus possesses exceptional Potions talent inherited from Eileen Prince and refined through years of instruction from Eileen and Manus. Professor Slughorn considers him more gifted than his mother and a potential future Potions professor. 147 403

• Began studying Potions with Manus under Eileen's instruction in childhood. 18 147
• Demonstrated the theoretical understanding needed to begin advanced brewing, though he initially lacked practical confidence. 143
• Endured repeated failures while attempting an updated Wolfsbane Potion, making progress through pressure and repetition. 144 148
• Identifies unnecessarily complicated potion structures and attempts to analyze the purpose behind each brewing step. 149
• Reviews Manus's Wolfsbane Potion paper for gaps in explanation and recognizes that Lily, with a different knowledge base, could offer a useful independent assessment of its clarity. 163
• Completes his second-year written and practical Potions examinations confidently alongside Manus and Lily. 403
• Studies the properties of Veritaserum rather than fearing it, immediately noticing its unusual quality after being administered a drop. 481 482
• Recognizes that Veritaserum interferes with the process of composing and censoring speech, causing him to answer without his usual deliberation. 482
• Modifies potion recipes in his own work, but considers Manus even more decisive when making experimental changes. 519
• Observes Manus's Potent Strengthening Potion experiment using Re'em horn powder and studies its implications for ingredient compatibility, cost, and practical safety. The resulting potion is not consumable, and Severus recognizes that such expensive research cannot serve as a straightforward model for his own work. 519 520

Wizarding Magic and Dueling

Severus combines precise casting with improvisational tactics rather than relying solely on direct attacks.

• Uses defensive and control spells including Glacius, Incarcerous, Flipendo, Finite, and Expelliarmus. 79
• Practices close combat enhanced by simple magic, exchanging several blows with Manus during a corridor ambush before they stop without a clear winner. 112
• Employs Mage Hand to compensate for limitations in Binding Charms and create casting advantages. 171
• Casts hexes while moving, making his timing and angles harder to predict. 171
• Uses low-risk disruptive magic—such as Tarantallegra and the Toenail-Growth Charm—to create openings for decisive spells. 170 187
• Trained to interrupt his own spells without dangerous magical backlash, improving his adaptability under pressure. 188
• Understands Manus's lesson that magical effectiveness depends on precision, efficiency, and circumstances rather than spectacular destructive effects. 189
• As of the change to Manus's Saturday schedule, lacks sufficient proficiency with non-verbal spells to follow Manus's newer dueling practice. He also cannot Apparate and has no authorization to practice Apparition at Hogwarts. 483

Occlumency and Mental Discipline

Manus trained Severus to think rationally and resist emotional instability, believing his upbringing could otherwise distort his development as a spellcaster. 41 54

• Uses Occlumency to counter a Daze Spell during his duel with Lily. 331
• Displays strong emotional resilience toward ordinary bullying and social rejection. 237
• Remains unable to reliably block Voldemort's Legilimency, making further Occlumency training essential if the Death Eaters target him. 234 236
• Can critically evaluate his own victories, identifying his lack of a sufficiently decisive offensive spell even after defeating Lily. This assessment contributes to his pursuit of a curse combining destructive power with a hex's speed and concealment. 171

Sectumsempra

Sectumsempra is Severus's self-created cutting curse, developed over several years for swift surprise attacks. 331 332

• Opened his successful attack on Lily by briefly dazing her, then cast Sectumsempra before she could recover. 331
• The curse bypassed Lily's defenses and nearly severed her wand arm. 331
• Ordinary healing magic could not repair its wounds during Severus's tests on rabbits. 331
• Its dedicated counterspell is Episkey (Vulnera-Sanentur), cast by tracing the wound. 331
• The counterspell requires a genuine desire to save the victim; artificial coercion cannot reliably reproduce the necessary emotion. 332
• Severus had not yet mastered non-verbal casting of Sectumsempra when he first used it against Lily. 332
• Manus later interprets the curse as an expression of the sharpness forged by Severus's family environment and the need to establish himself in Slytherin without powerful family backing. Developing its counterspell alongside it demonstrates that Severus's aggression has limits and can be restrained. 591

Magic Model Studies

Manus formally introduced Severus to a broader magical system distinct from standard wand magic, treating him as a potential fellow practitioner rather than merely a Hogwarts student. 237

• Received more than thirty notebooks of condensed foundational theory before beginning formal instruction. 237
• Completed the introductory material, gaining deeper understanding alongside a growing number of more precise questions. 291
• Endured demanding holiday study targets while balancing Manus's lessons with Hogwarts coursework. 293
• Experiments with magical models while continuing his Potions and Dark Magic research. 373
• Chose Conjuration as his primary school, despite having already created a Curse-level spell through the wizarding system. 428
• Studies magic through linked principles and structures rather than rote spell memorization. 428
• Manus identifies a significant limitation in Severus and Lily's development: having possessed magic naturally, they cannot reproduce the foundational experience of constructing magical power from the beginning. Based on their progress at that time, he considers advanced techniques such as Empower Spell, Maximize Spell, Extend Spell, Multi-track Casting, Delayed Release, and Prepared Trigger beyond their reach. 448
• Manus later judges Barty Crouch Jr.'s aptitude for Charms and deep magical theory as potentially greater than Severus's or Lily's, while emphasizing that talent varies between disciplines. 512

Other Magical Studies

• Cannot perceive qi sufficiently to use Manus's Longhorn Beetle Chessboard for detecting danger in Cokeworth. Manus associates this failure with the absence of the metaphysical foundation needed for Qi Magic. 344
• Studies Divination under Professor Tracey and becomes concerned when he learns that its examinations cover extensive theory and history beyond the textbook. 474

Equipment / Items

• Walnut wand — Thirteen and a half inches, reasonably supple, with a dragon-heartstring core. 79
• Potted Wiggentree — A gift from Manus that Severus protects closely; Manus upgrades it annually. The plant later detects a Werewolf at Hogwarts. 54 144
• Foundational magic notebooks — More than thirty notebooks supplied by Manus as preparation for formal study of his broader magical system. 237
• Veritaserum — Receives a bottle from Professor Hesper Staky, then arranges for Professor Slughorn to keep it securely in supervised storage. 482 483
  • Staky warns him never to use more than three drops, since excessive quantities can damage the brain. 482
  • Severus's storage plan allows him to retrieve it during supervised Potions study while using Slughorn's reputation to discourage theft and rumors. 483

Relationships

• Manus — Childhood friend, mentor, protector, and advanced-magic instructor. Manus offers Severus refuge from his home life, trains his rational thinking and combat ability, and prepares him for the possibility of Death Eater coercion. 3 5 237 He respects Severus's right to pursue goals independent of his own research and does not intend to keep him permanently attached to his Mage Tower. When Severus struggles with his new freedom, Manus offers companionship rather than imposing another direction. 463 520 Severus remains protective of him, urgently warning him about Slytherin's reaction to his claim that Muggles can use magic. 628
• Lily Evans — Closest friend and competitive sparring partner. Their cross-House relationship is kept discreet when necessary, but they exchange intelligence, study together, and repeatedly push one another to improve. 68 100 353 She comforts him after his Magic Mirror vision and later attempts to climb down the castle walls to reach him during the Great Lake incident, leaving once she sees that he is unharmed. 112 482
• Eileen Prince — Mother and first Potions teacher. Severus's ambition is strongly tied to giving her financial security and the freedom to live without sacrifice. 18 148
• Tobias Snape — Muggle father. His resentment of magic, alcoholism, and abusive behavior shaped Severus's early life; Severus ultimately rejects the possibility of serving Voldemort even if ordered to kill him. 2 48 236
• Aivina — Manus's mother and Eileen's former classmate. She warmly welcomes Severus into her home, feeds him, and treats him with familial affection. 1
• Horace Slughorn — Potions professor who recognizes Severus's exceptional talent, recalls Eileen's potential, and suggests that Severus could eventually succeed him as Hogwarts's Potions professor. 147 403 404 Severus entrusts him with the secure storage of his Veritaserum. 483
• Hesper Staky — Potions master who offers Severus guidance after determining that he was uninvolved in the Great Lake fight. She was expected to become Hogwarts's Potions professor after her temporary Defense Against the Dark Arts duties. 482 Her anticipated future appointment does not occur before she is killed; Manus later refers to her death in analyzing Dumbledore's strategy against Voldemort. 601
• Hagrid — Shares a relaxed meal with Severus and Manus after Manus recognizes Severus's uncertainty about his future. Hagrid grills the enormous steaks Manus provides, while Severus prefers his portion more thoroughly cooked. 520

Story Role / Major Arcs

• Cokeworth childhood — Confides in Manus about Tobias's abuse and comes to understand that his parents' marriage is not the loving relationship he imagined. 2 3
• Early magical education — Experiences his magical outburst, studies Potions under Eileen, and receives extensive mental and magical training from Manus. 18 54 65
• Hogwarts entry — Is sorted into Slytherin, obtains his wand, and continues training with Manus and Lily despite increasing House tensions. 79 86
• Magic Mirror revelation — Sees a happy family with his parents as his deepest longing, revealing the emotional desire beneath his guarded exterior and professional ambitions. 112
• Wolfsbane assessment — Struggles through Manus's deliberately demanding Wolfsbane Potion training after the Wiggentree detects a Werewolf at Hogwarts. 144 145 148
• Research review and mutual accountability — Helps review Manus's Wolfsbane Potion paper and suggests involving Lily. The extra work contributes to Lily's sleepless night and an angry confrontation during practice, forcing Severus to recognize the consequences of his suggestion. 163 168
• Death Eater dilemma — Learns that Slytherin students are being recruited by Death Eaters and rejects the illusion that he could join Voldemort in a harmless support role. 234 236
• Advanced magical studies — Accepts Manus's offer to learn a separate, broader magical discipline and completes its foundational curriculum. 237 291
• Sectumsempra development — Defeats Lily with his completed original curse, establishing himself as both a dangerous duelist and a spell inventor. 331 332
• Career planning — Considers becoming a Potions master and eventually teaching at Hogwarts, while maintaining broader academic and professional alternatives. 353 403 404 He also considers publishing his research, but recognizes that its emphasis on Dark Magic complicates open sale, distribution, and profitability. 373
• Great Lake questioning — Is questioned with Veritaserum by Staky and cleared of involvement in the fight. He receives a bottle of the potion, an offer of Potions assistance, and a warning from Manus to secure it. 482
• Independent Saturdays — Places the Veritaserum under Slughorn's supervision and gains freedom to arrange his Saturdays after Manus begins separate dueling lessons with Flitwick. His initial excitement gives way to renewed study because of concerns about his family and the Death Eaters. 483
• Re'em potion experiment and research uncertainty — Observes Manus's costly Potent Strengthening Potion experiment and recognizes that its methods are financially impractical for him. With his spell research stalled and his schedule no longer tightly directed, he considers Beauty Potions as a more profitable path. Manus responds to his uncertainty by inviting him to a meal at Hagrid's. 519 520
• Warning of Slytherin opposition — Urgently alerts Manus that Slytherin students are reacting to his statement that Muggles can use magic. Manus reassures him that the confrontation was anticipated and sends him back to preparing a potion while handling the students himself. 628
