Background / History

Sixth Prince and University Professor

Kavin shares a body with Carven Lucian, the Kingdom of Lucian’s sixth prince. Dill and Lucian are distinct personalities rather than merely different names. By the time Lister meets them, Lucian rarely emerges unless Dill deliberately brings him forward, and the royal family already knows about their condition 38 39.

Despite his royal birth, Kavin states that he has supported himself since age six through inventions and business. He separates his interests from those of the royal family and refuses to treat valuable royal intelligence as payment for damage to his own property 38.

Lister approaches him while seeking an introduction to the king. Kavin agrees to arrange a meeting after hearing about a massive turquoise vein, then negotiates a separate agreement for information about an intact alchemical city beneath the Lost Land. Lister requests 20% of the exploration gains; Kavin accepts only on the condition that the ruins match the description 38 39.

Founding the Church of Mechanical Truth

Exploring the Alchemy Ruined City brings Kavin into contact with Hoffman and his ancient society of mechanical life. Kavin assembles an Alchemical Mechanical Giant and awakens a new consciousness within it, intending to station it outside the city as a protector 105.

When Lister questions whether mechanical civilization would eventually reproduce humanity’s conflicts, Kavin proposes a wager. He declares his intention to create a new civilization, encourage mechanical beings to develop self-awareness, and establish the Church of Mechanical Truth 105.

The ruins yield more than he expected. As an additional reward for Lister’s information, Kavin builds an S-type avian construct around an S-grade energy crystal. This construct becomes Jiji and also serves as a means of contacting him 107.

Federation Campaign and Exile

Kavin develops his civilization in the Chaotic Star Region while affiliated with the Leviathan Civilization. His strength attracts Federation military attention after he kills Tuan Fleming and annihilates a full-strength fleet without allowing information to escape 165 228.

During the subsequent campaign, Lister secretly supports Kavin while maintaining the appearance of carrying out Federation orders. Kavin prepares to evacuate his civilization using a Forbidden Magic Teleportation Array rather than abandon its population 229 230 231.

Kavin and Lister later stage a fierce battle while deliberately holding back. The Federation force retreats, but Commander Vidal subsequently destroys the core star region and kills Kavin’s decoy. The real Kavin survives, while Hoffman loses the puppet that protected his escape 234 236.

The destruction turns Kavin’s hostility toward the Federation into an explicit vow of revenge. He and Hoffman plan to rebuild beyond its territory, and Lister promises to help when they return 236.

Babylon Galaxy and Fourth Evolution

Kavin and Lister launch the Church’s occupation of the Babylon Galaxy with mechanical armies and Jiji’s Evil Shadow Mechanical Birds. After the remaining resistance is eliminated, the Church begins restructuring planets and inscribing metal runes into their cores to create a realm suited to mechanical civilization 264 269.

The former Star Matrix Civilization’s soul-nurturing space becomes central to this development. Kavin supervises experiments that strengthen mechanical souls, checking whether the process preserves the participants’ identities despite its dangerous memories and bodily mutations 269.

He later undergoes his fourth evolution there. His armor becomes a nanoscale cocoon interwoven with alchemical runes, his chest core undergoes a qualitative transformation, and twelve phantoms representing earlier stages of his life merge back into him. His breakthrough produces the completed solution to the Theory of Mechanical Life Evolution on the space’s inner walls 275.

Return Against the Galactic Federation

After becoming a Truth Sage, Kavin joins Lister, Wang Yue, and Hoffman in preparing their revenge. Boren Leviathan transfers authorization over his unstable symbiotic mechanical core to Kavin, who discovers high-dimensional collapse and warns that he cannot control it—only attempt to exploit its existing rules 275.

In the fighting against the Federation’s Hegemons, Kavin dismantles and kills Aogelie, confirming his World-Ending strength to the enemy. He then shields Boren from Zion’s annihilation flames, although the attack overloads and cracks his armor 280.

After the New Galactic Federation is formed, Kavin helps uncover Void Corridor infiltrators. He supports the creation of a new cosmic power with Lister while remaining more interested in improving himself and developing the Mechanical Civilization than in political prestige 286.

Ancient Machine Holy Grail and Star Machine Conflict

At the Ancient Machine Kingdom ruins, Kavin discovers the Ancient Machine Holy Grail and encounters Ruler Two of the Star Machine Civilization. Their disagreement is ideological as well as territorial: Ruler Two rejects Kavin’s human body and his doctrine of autonomous mechanical life coexisting with other lifeforms 300.

The Holy Grail recognizes Kavin with 99.7% mechanical-origin compatibility and grants him its highest authority. Through it, he learns about the Ancient Machine Kingdom’s destruction and identifies the Star Machine Civilization as a branch that deserted it 301.

Ruler Two’s Mechanical Poison nearly destroys Kavin’s underlying mechanical logic. The Holy Grail activates to counter the poison, but the competing energies leave him critically weakened. Lister’s saber intercepts the attack aimed at his forehead 303.

Kavin subsequently claims the Star Machine Civilization as his target—not only for revenge, but to obtain its inherited mechanical knowledge. During the later offensive, he seizes enemy detection matrices and identifies the location of Dominator One more accurately than the supplied intelligence 305 314 318.

Later Campaigns

• Machine Creation Ring: Identifies the Star Machine Civilization’s galaxy-scale weapon as a realization of an Ancient Machine Kingdom project. Uses the Holy Grail to reinforce shields protecting Lister and Ocas from amplified Star Core Disintegration Rays 319.
• Emerald Royal Court invasion: Activates the Star Machine Civilization’s Ultimate War defense protocol. Holds off Varalos and deflects Aiselyn’s arrow, but cannot stop Sailianna’s Wither from draining his life force before Lister intervenes 327 328.
• Elf Plane campaign: Leads mechanical legions against the dark elves. Combines attacks with the Spirit Remains Lord and Eternal Night King to mortally wound a World-Ending dark elf king, then competes with them for the finishing blow 346.

Appearance

• Expression: Usually rigid, cold, and almost mechanically emotionless. When the Lucian personality emerges, his face becomes visibly anxious and animated 37 38.
• Eyes: Pale gold, a trait associated with the Lucian royal bloodline; formulas, warnings, and data streams appear in his vision during mechanical operations 275 303.
• Armor: Wears mechanical armor, described as silver-white in battle. During his fourth evolution, it disassembles into nanoscale particles and forms a translucent cocoon 275 280.
• Mechanical appendages: Uses mechanical arms mounted behind him, including energy cannons for close-range combat 234.

Personality

Dill is methodical, direct, and committed to equal exchange. His lack of visible emotion does not prevent negotiation or conversation: he accepts noncash compensation, defines contractual conditions precisely, and distinguishes personal benefit from royal benefit. He is also unusually sensitive to Lister’s emotional reactions 37 38 39.

His strongest enthusiasm is reserved for knowledge. News of ancient alchemical technology briefly breaks his impassive expression, and his later pursuit of the Star Machine Civilization is driven partly by its technological inheritance 38 314.

His concern for mechanical life extends beyond military utility. He wants to preserve Hoffman’s city, foster self-awareness, and allow mechanical beings to pursue their own goals. Nevertheless, the Federation’s destruction of his civilization leads him to embrace retaliatory war, and he later describes war as the best means of accelerating evolution 105 236 275 300.

Lucian contrasts sharply with Dill: he is fearful of responsibility, believes his father never favored him, and calls himself a disgrace to the royal family. Even the suggestion of handling an important royal matter provokes a panicked refusal 38.

Original Game Timeline

These details belong to Lister’s memories of the game before transmigration, rather than automatically describing events completed in the altered timeline.

• Kavin becomes a notorious founder of the Church of Mechanical Truth, known as the Madman Mechanic and Truth Mechanic. Mechanical-class players are especially interested in joining his faction 35 36.
• The Church plans a Galactic Big Bang intended to destroy the Milky Way, but the plan is stopped 106.
• The Church eventually supplants the Star Machine Civilization as one of the universe’s seven great superpowers and fights the Void Corridor 278.
• Its elevation to superpower status follows its destruction of the Star Machine Civilization, rather than a deliberate pursuit of that title 286.
