The Aegisblood Circuit

“Blood may betray, but copper remembers loyalty.”
— Inscription etched on early prototypes recovered from the catacombs beneath the Basilica Arcanii.

The Aegisblood Circuit is an arcano-technological device developed by the Imperium to suppress or delay magical transformations—chiefly the irreversible mutations wrought by Rift exposure, Lycanthropic inheritance, or unstable mage-blood awakenings. It operates not as a cure, but as a temporal shield—granting time for containment, treatment, or choice.

Its use is common among Riftborn battlemagi, inquisitorial agents, and those cursed with delayed transformations. In some provinces, it is also worn by noble heirs carrying unstable arcane bloodlines, preserving their sanity and form long enough for political marriages or rituals of purification.

Utility

Primarily, the Circuit is worn over the upper back or sternum, fused partially into the skin through alchemical bonding. Once activated, it channels aetheric pulses in harmony with the wearer’s heartbeat, dampening internal arcane surges.

It was originally conceived to aid mage-initiates with unstable bloodlines but found broader application during the Rift Plague Panics of the 400s AR.

Some rebel factions have begun misusing the tech to delay detection of magical corruption, masking their nature from Divinatory rites.

Manufacturing

Aegisblood Circuits are forged within sanctified laboratories of the Basilica Arcanii, using copper drawn from the subterranean veins of Monte Aurum. Each unit must be attuned to the blood of the intended host through ritual bleeding, binding the circuit to their essence.

The final inscription is etched by hand, typically by an Arcanii master, invoking protective hexameters said to resist the entropy of change.

Social Impact

Among the nobility, the Circuits became both symbol and scandal—proof that even imperial blood could falter under the Rift’s gaze. Some see them as chains worn by cursed heirs, others as medallions of courage and duty.

For the poor, their absence is often fatal.

Religious orders debate the ethics of such delay: is defiance of transformation a rejection of divine metamorphosis, or an affirmation of the soul’s integrity?

Inventor(s)

The prototype was developed by Magister Caelia Varistus, Praeceptor Emerita of the Basilica Arcanii, in collaboration with the Inquisition’s Bio-Arcanum Division.

Caelia vanished in 391 AR under unclear circumstances. Her last lecture, transcribed by her students, concluded with:

“Not all gods wait for worship. Some wait for the right mutation.”

Access & Availability

The device is classified as Imperial Arcanii Property. Use by civilians requires explicit writs from the Basilica Arcanii or an Inquisitorial Seal of Compassion. Unauthorized possession is considered a form of biothaumaturgical treason.

However, black-market imitations—less stable and often more dangerous than the condition they attempt to forestall—have appeared in districts such as Blackmerrow and Thornegate.

Complexity

Construction requires integration of three technological and magical disciplines:

  • Hematurgic Alchemy – to isolate and stabilize the wearer’s aether signature.
  • Runic Circuitry – using coiled silver and Riftsteel etched with specific delay-glyphs.
  • Resonant Copper Mesh – an exo-nervous web interfacing directly with bloodflow.

Without expert calibration, the circuit may amplify symptoms or cause permanent stasis—a living death where one is frozen in the threshold state.

Discovery

The Aegisblood Circuit emerged during the Second Surge of the Waking Moon (circa 382 AR), when transformation outbreaks spiked across Obscurum and Ascensus. The Arcanii, under Magister Caelia Varistus, began research into copper-bound aether channels after discovering that blood treated with refined “Redroot Mercury” resisted Rift-triggered anomalies.

In an early test involving a Rift-touched legionnaire—subject: Marcus Eborius—the circuit successfully delayed his transformation into a feral null-form by nine lunar cycles. His final message scrawled into a leather-bound tome read simply: “Buy time. It buys hope.”
