Merlin

Merlin is Kroft's senior apprentice and Abyssal Bone Forest Academy's most celebrated young Potioneer. He develops his talent through intensive laboratory work backed by a Magus family, becomes a Level 3 acolyte, and wins the academy's Potioneering competition. The reputation created by those achievements also makes him a priority target during the inter-academy bloodbath.

Biography

Kroft's prodigy

Before Merlin enters the narrative directly, Bicky and Kroft describe him to the newly accepted Leylin Farlier as a once-in-a-century Potioneering talent and the apprentice most likely to inherit their mentor's work. Leylin then sees an extremely tall, taciturn senior who spends nearly all his time bent over experiments. Merlin's limited conversation is not indifference to his craft; concentration and repetition are presented as central reasons for his success. (Chapters 23–24)

That success is expensive. Merlin consumes large quantities of ingredients and practises continuously, yet still needs roughly a month to produce his first successful potion. The result is exceptional by ordinary academy standards and establishes the public benchmark Leylin uses to disguise the A.I. Chip's much faster optimisation. When Leylin presents his own first Strength Potion, Merlin interrupts his experiment to watch and then personally congratulates him instead of responding with open resentment. (Chapters 25 and 27)

Contracted advancement

Merlin solves the resource problem by signing a contract with a Magus family. The family provides ingredients in volumes an independent acolyte could not easily afford and promises resources that may help him attempt advancement to official Magus. In return, once he reaches Level 3 he must supply a fixed quantity of potions each month and join the family if he becomes an official Magus. The arrangement accelerates his training but also commits his future labour and affiliation. (Chapter 38)

The supporting family later sends Merlin outside the academy on a mission lasting at least one to one and a half years. The assignment also removes a valued fifth-grade acolyte before conditions at Abyssal Bone Forest grow more dangerous. By the age of twenty-one, he has reached Level 3 acolyte—a strong result that gives him a realistic chance of attempting the transition to official Magus, even though he never completes that advancement in the supplied story. (Chapters 40 and 80)

Competition and bloodbath

After returning to the academy, Merlin has become more mature and stable, but remains recognisable by his damaged face and reserved manner. He and Leylin advance together through the academy Potioneering competition while Bicky is eliminated in an earlier round. The final requires Hofdor's Water of Radiance, a difficult beginner potion used against injuries caused by negative-energy spells. Leylin believes he can brew it with the A.I. Chip but deliberately introduces an error, leaving Merlin the legitimate public winner. (Chapters 82 and 87)

The victory cannot protect Merlin from the academy conflict. A binding agreement forces the leading fifth-grade acolytes of three hostile academies into a shared secret-plane bloodbath. Merlin's Potioneering reputation marks him as an exceptional future resource and therefore a strategic target. Enemy acolytes concentrate their attacks on him, and he is killed before reaching official Magus. Kroft's subdued grief after the bloodbath reflects the loss of his expected successor, while Leylin becomes his best surviving apprentice. (Chapters 83, 88, and 98–100)

Names that do not belong to him

Two other uses of “Merlin” are separate identities. Merlin Falek Driwilc, named as the historical founder of Abyssal Bone Forest Academy, predates Kroft's apprentice by centuries. Much later, Leylin creates a limited A.I. persona called Grandpa Merlin inside a ring to manipulate people in the Twilight Zone. That persona's Sacred Flame instruction, predictions, relationship with Aaron, and involvement with the Meteor Sword belong to Leylin's artificial role, not to the deceased Potioneering acolyte. (Chapters 20 and 347–381)

Appearance and personality

Kroft's apprentice is extremely tall and taciturn. He remains absorbed in experiments and interacts little with anyone outside Kroft's laboratory, especially compared with the more openly affectionate Bicky. An experiment burns and irreparably damages part of his facial musculature, leaving him unable to form ordinary expressions; an intended smile can therefore look strained or uglier than crying. After several years away, his features change little, though his temperament appears steadier and more mature. (Chapters 24–25 and 82)

He is defined more by work habits than by speeches. Merlin accepts repeated failure, consumes costly ingredients, and continues experimenting until results become reproducible enough to support a contract. He is also gracious within the limited evidence available: when Leylin's success creates an obvious comparison between them, Merlin walks over to congratulate his junior. The narrative does not provide enough private viewpoint to infer broader ambitions or resentment. (Chapters 24–27 and 38)

Magic, bloodline, and abilities

Potioneering talent and method

Merlin is the academy's leading acolyte-level Potioneering talent without the computational advantage that secretly supports Leylin. His method is sustained empirical practice: he uses large batches of ingredients, repeats procedures, learns through failed brews, and gradually reaches a saleable success rate. Even his exceptional first success takes about a month of continuous work and extensive resources, showing that talent reduces the learning curve but does not remove material cost or experimental failure. (Chapters 23–27)

His reputation is supported by concrete outputs. Merlin can brew potions profitably enough that academy merchants seek his products, develops at least one new potion during Leylin's early training, supplies an outside family under contract, and reaches the final of a formal competition. There he successfully produces or outperforms Leylin on Hofdor's Water of Radiance after Leylin deliberately fails. The potion's difficult negative-energy healing application tests precision rather than raw destructive power. (Chapters 24–28, 38, and 87)

The family contract reveals both the engine and limit of his progression. A steady ingredient supply lets Merlin practise far beyond what a poor acolyte could finance, while promised advancement resources address the next bottleneck. In exchange, he owes monthly production and future service. His expertise therefore becomes economically valuable before it makes him personally secure. (Chapter 38)

Acolyte cultivation

Merlin is a fifth-grade aptitude acolyte who reaches Level 3 at twenty-one. That level requires constructing mind runes and reinforcing the sea of consciousness, and it places him among the academy's best prospects for official Magus advancement. It also allows access to Rank 0 spells in principle. The supplied chapters do not name a combat spell cast by Merlin, describe his elemental affinities, or show him winning a magical duel, so no specific offensive repertoire can be attributed to him. (Chapters 40, 80, and 83–88)

Practical limits

Merlin's strongest field is preparation in a laboratory, where time, ingredients, and repetition can be converted into reliable products. The bloodbath removes those advantages. His fame tells enemies that he may become strategically important, while his current Level 3 body remains an acolyte's and cannot survive concentrated attacks by rival elites. His death illustrates a central limit of specialised skill: valuable Potioneering does not automatically provide equivalent combat survivability. (Chapters 88 and 98–99)

Relationships

• Kroft: Merlin's mentor, instructor, and strongest advocate. Kroft regards him as a likely successor and is visibly affected when the bloodbath kills him.
• Leylin Farlier: Merlin is Leylin's senior and public benchmark in Potioneering. Leylin hides the A.I. Chip by appearing slightly less talented, deliberately yields the competition final, and later reuses Merlin's name for an unrelated artificial persona.
• Bicky: A fellow apprentice in Kroft's laboratory and one of the few people with whom the taciturn Merlin regularly interacts.
• Supporting Magus family: An unnamed family finances Merlin's ingredients and potential advancement in exchange for monthly potions, missions, and his future affiliation.

Items

• Laboratory apparatus: Merlin works constantly with test tubes, experiment benches, and ordinary Potioneering equipment. The corpus does not identify a unique personal cauldron or artifact. (Chapters 24–27 and 82)
• Potion ingredients: Large and repeated ingredient supplies are the material basis of his training. They initially make progress expensive and later become the principal benefit furnished by his family contract. (Chapters 27 and 38)
• Hofdor's Water of Radiance: The difficult negative-energy healing potion assigned in the competition final. It is evidence of Merlin's practical brewing level, not a permanent possession or combat technique. (Chapter 87)
• No Meteor Sword: The Meteor Sword is associated with Leylin's later Grandpa Merlin persona. Kroft's apprentice neither owns nor helps forge it. (Chapters 350–381)
