Solfis's processing core

Solfis's processing core is the surviving heart of an Old Empire experimental war golem, and its recovery transforms an inert archaeological weapon into an active companion and strategic resource. The core preserves Solfis’s identity, enables the golem to perceive and communicate, and remains the indispensable component that allows Solfis to be transferred between frames and restarted when Viviane Saint-Lys is under attack.

Definition and Original Construction

The core belongs to a unique experimental war golem created by the grand engineer Irlefen. The construct was designed as a dedicated mage and monster killer and is described as one of the Old Empire’s secret weapons, a work whose quality has not been equaled since its creation. Its original body stands apart from the gutted golems surrounding it: the armor is more elaborate, covered with gems and faded runes, while the hands and the handsome-man face mask are made with an almost human delicacy. The weapon’s appearance therefore joins extreme military purpose to painstaking craftsmanship.

The processing system is not a minor component inside that frame. It is effectively the core’s identity-bearing center. When Viviane Saint-Lys first encounters the golem, the power source is exposed and gives off only a weak pale-blue light. Three small crystals remain connected to it by cables, while a pile of exhausted crystals lies farther away; the processing units have been removed and arranged in neat rows on a tarp. The damaged installation makes the core’s condition ambiguous: the machine looks dead, yet its eyes flash yellow, announcing that something within it remains active.

Binding and Removal

Solfis’s processing core can be bound to Viviane Saint-Lys through blood. The binding instruction requires her to place a droplet of blood in the processing unit’s binding node. Because she lacks a proper tool, Viviane opens her skinsuit, exposes an arm, and uses the claw of an ancient golem to draw blood, accepting an improvised and uncertain method because no better instrument is available. The act turns an inaccessible relic into an object that recognizes her authority.

After the blood is accepted, the core reports that its analysis is complete and identifies the body’s time of existence as one day, with its stated place of origin consistent with the surrounding mana distribution. These readings connect Solfis’s activation to Viviane’s arrival in the world rather than to an uninterrupted survival across the centuries. The core is thus both ancient in manufacture and newly embodied in the present.

Viviane later removes it from the golem frame. She unplugs the power cable and the connection linking the processing unit to the frame’s other systems, then works through numerous braces and locks before pulling it free. The parts remain intact and are made largely of smooth silvery metal that has survived the passage of time. Viviane suspects that binding Solfis has granted her an access level, since the locks require no key. The operation succeeds without incident, but the result is physically demanding: she must deadlift the heavy, exquisitely made core and plan how to carry it in her backpack or a separate bag.

Portable Existence and Practical Burden

Once removed, the core cannot function as a complete body. Solfis explains that Viviane must attach a portable sensor suit so that the processing unit can perceive the world and interact with her. The unit is voluminous and probably needs its own bag, making it a cumbersome object rather than a conveniently portable companion. Viviane considers carrying it in her hands or placing it in a sleeping bag over her shoulder, recognizing that its weight and shape will slow her movement.

This practical inconvenience gives the core a second identity within the story. It is at once a priceless remnant of Old Empire engineering and awkward luggage that must be protected during travel. Its value does not eliminate its material demands; the more important it becomes to Viviane, the more directly she must accommodate its bulk. The core’s status as a person-bearing machine therefore remains inseparable from the labor of transporting and housing it.

At Fort Sky, Solfis’s continued immobility becomes an immediate objective. After Viviane has secured food, quarters, and identification papers for herself and Arthur, Solfis insists that work on a new frame begin without delay. Viviane agrees to help and acknowledges that Solfis is waiting to move independently again. The core makes that demand possible because it preserves a continuous consciousness even while the original body is unavailable.

Reactivation in a New Frame

The core’s decisive function appears during the crisis at Fort Sky. Viviane is weak, unable to cast, suffering from empty conduits and a severe headache, while soldiers rush her into a tower room and bar the doors. Solfis announces that startup is imminent and instructs Viviane to place a droplet of blood on the rune engraved on its forehead. She has no time for another plan: Solfis is the only available defense, and she attempts to comply even as Cernit tries to stop her and then supports her under the shoulder.

When the ritual is completed, Solfis’s thin ribs close around the core and the new body initializes. Two yellow orbs appear in the skull’s orbit, recalling the eyes of the first frame in Harrak. The voice remains recognizably Solfis’s, but the new frame carries an ominous, organic snarl that the earlier metal body lacked. The core consequently does more than power a replacement shell: it carries memory, voice, and identity across radically different bodies while allowing each frame to alter how Solfis is perceived.

The activation formally identifies the new body as the HX-013 experimental strike golem designated Solfis. The processing core is the continuity behind that designation. Without it, the reconstructed frame would be only an arrangement of metal and systems; with it, the machine returns as the same dangerous intelligence that Viviane first discovered in Harrak.

Relationships and Narrative Significance

The core establishes the material foundation of Viviane Saint-Lys’s relationship with Solfis. Blood binding makes their connection reciprocal but unequal in practical terms: Viviane must find, remove, carry, power, and eventually install the core, while Solfis supplies technical knowledge, translation, and protection. Their partnership repeatedly turns an object of immense weight into an active participant in decisions, travel, negotiation, and combat preparation.

Its presence also shapes Viviane’s social position. Solfis’s capabilities strengthen her bargaining position when she negotiates for private quarters, adequate food for Arthur, identification papers, and a salary. Later, official documents identify Viviane as a mercenary in the service of the Church of Neriad, while money and recommendations help prepare her movement toward Kazar. The core itself is not exchanged for those benefits, but its existence makes Viviane’s unusual circumstances and potential useful enough to support such negotiations.

The object’s significance is sharpened by contrast with the worlds around it. It comes from the Old Empire, whose former seat of power in Harrak has become a dead city of basaltic sand, monumental ruins, and mindless undead. The same civilization that once terrified the world through unmatched magical ability survives materially in relics such as this core. Yet the relic is not merely a museum piece: after centuries of imperial ruin, it becomes mobile, relational, and operational again. The core therefore embodies the book’s recurring tension between dead history and usable inheritance, preserving the past not as a monument but as a force capable of reentering the present.
