Fizzy's journey into the Horkensaft Kingdom begins steeped in unresolved grief and a peculiar form of narcissism. She confesses to her inner voice, Plus, about the emotional void left by Boxxy's death, likening it to losing an arm she can never get back. This metaphor, misunderstood by Jess, highlights Fizzy's complex emotional landscape: a creature of pure mithril, incapable of physical pain, yet deeply wounded by loss. Jess, increasingly unnerved by Fizzy's unsettling demeanor and violent outbursts, finally confronts her. She accuses Fizzy of being a "psychopath" who murders for pleasure, not justice, and points out how this likely led to her "dumping" by Keira. Jess's blunt honesty forces Fizzy into a rare moment of vulnerability, admitting to a "red haze" that overcomes her. Despite a fleeting promise to change, Jess refuses to continue traveling with Fizzy, abandoning her in the bustling dwarven city of Steelhead. This leaves Fizzy isolated, publicly shamed, and, as she soon discovers, utterly broke. During her internal pep rally, one of her three Bags of Holding is stolen, containing all her money and, crucially, the cursed shield-gauntlet that initiated her golem transformation. Alone, penniless, and stripped of her most potent magical item, Fizzy faces a fresh start, ironically believing this "third time was the charm" for her survival.

Fizzy's desperate situation in Steelhead is abruptly resolved through a display of her chilling power. She tracks her stolen gauntlet to a young gnome, Moss, who is now suffering a petrifying curse from the item, slowly turning to steel. A dwarven cop attempts to intervene, but Fizzy, without hesitation, commandeers his axe and brutally severs Moss's arm to reclaim her gauntlet. The cursed item, the Left Hand of the Forsaken Sentinel, immediately re-attaches to Fizzy's stump, restoring her left arm to its original mithril glory. She then "heals" Moss with Holy Light, curing his petrification but leaving him with the agonizing memory of his amputation. Fizzy's interrogation of the terrified Moss is a masterclass in psychological manipulation, using intermittent healing to prolong his suffering and extract information about his accomplice and his own past. She renames him "Moss" and, with chilling pragmatism, forces him to act as her "owner" to bypass golem travel restrictions, promising him a new prosthetic arm as part of their uneasy alliance.

Fizzy and Moss embark on their mag-rail journey to Gun Tarum, where Fizzy's Artificer curiosity blossoms as she remotely studies the train's advanced mechanics. Their compartment, however, is soon invaded by Sally and Ollie, thugs who believe Moss's enchanted wand is Fizzy's "control rod." Fizzy, with cold calculation, plays along, allowing Sally to "reset" her. The command unexpectedly works, forcing Fizzy into a stiff, blank state, revealing a hidden layer of susceptibility. Feigning compliance, Fizzy uses her wit and a deliberate "malfunction" to humiliate Sally, mispronouncing her name and then disarming Ollie with Magnetize, slicing off his beard, and presenting it to Sally as "something to eat." The ensuing chaos and Sally's enraged retreat are deftly handled, with Fizzy and Moss convincing the arriving guards that it was merely a "golem going berserk" due to magnetic interference. This chaotic display of power and manipulation, however, is overshadowed by a fleeting glimpse of a red-haired catgirl in Dragunov, a figure eerily reminiscent of her former Hero, Boxxy. This sight sends Fizzy into a frantic chase, reigniting a desperate hope that Boxxy might still be alive.

Fizzy's impulsive chase leads her to Novyy Dragunov, the hidden underground facility of Ekaterina Dragunova, the legendary Original Artificer, whom Fizzy now believes is somehow connected to Boxxy. Katya, a brilliant but ruthless android avatar, reveals her long-standing war with the stoneborn over the Realmstone, a massive mana regulator. She offers Fizzy an alliance, promising aid in exchange for her unique combat prowess. However, after Fizzy's initial success in a shardling hunt, Katya betrays her, attempting to hijack Fizzy's core with a custom Universal Control Rod hidden within a replica power pack. This physical intrusion bypasses Fizzy's mental defenses, but her Parallel Plot Skill activates, bringing Plus and Minus into full consciousness, allowing them to fight for control of her body. In this desperate struggle, the God of Happenstance intervenes, pulling Fizzy and her alter egos into a divine realm. The deity reveals Katya's numerous Taboos against the gods and grants Fizzy immense divine blessings, appointing her "High Templar of the First Underworld Crusade" to wage war against Katya and liberate the stoneborn.

Empowered by the gods and leading a stoneborn army, Fizzy returns to Novyy Dragunov to face Katya. She strategically deploys the divine blessings: Boundless Reserves for stamina, War's Righteous Might for artisan enhancements, God of Earth's Divine Protection for resilience, Lifebinder's Seal for anti-death wards, and Physics Be Damned to deflect enemy attacks. These boons transform the stoneborn into a formidable force, allowing them to withstand Katya's advanced laser weaponry. Fizzy, now a Dynamo Golem, utilizes her Magitech Cannon, Static Field, and Lightning Warp to devastating effect, tearing through Katya's automata. She confronts the true Ekaterina Dragunova, a withered old human encased in a life-support pod, and with a Magitech Cannon blast, brutally incinerates her. The facility self-destructs, revealing Katya's decades-long war was futile as the Realmstone was immutable. Fizzy escapes the explosion using a Realm Key, emerging on the surface, having liberated the stoneborn and connected their isolated world to the wider surface, fulfilling a divine decree while pursuing her own chaotic agenda.

Returning to the surface, Fizzy is summoned by the God of Happenstance, who reveals the full extent of Boxxy's resurrection: not only is he alive, but "livelier now than he was before," having escaped Death itself. Plus and Minus, now fully independent entities, have become permanent inhabitants of Fizzy's mind, each with their distinct personalities and contributing to her internal dialogue. The God of Happenstance confirms the pantheon's support for Fizzy's "crusade," not for altruistic reasons, but because Katya had angered them and Fizzy's chaotic nature offered "entertainment." This divine intervention has solidified Fizzy's role as a herald of change, her actions having forced the isolationist stoneborn to connect with the surface world. Now, armed with immense power, a clear understanding of the gods' whimsical nature, and the exhilarating knowledge of Boxxy's return, Fizzy embraces her new purpose: to find her beloved, chaotic Hero and reunite with him, bringing herself as the "greatest gift" he could ever want. Her journey, once an escape, has become a determined quest for reunion, guided by chaos and an unwavering, if brutal, loyalty.
