Synthetic blood

Synthetic blood, known in Vey’Zari clinical usage as artificial biofluid, is a widely used engineered fluid designed to replace or supplement natural blood in individuals who have undergone extreme levels of cybernetic augmentation. It is not a trauma-response tool or emergency treatment—instead, it is a systemic adaptation used in planned procedures where the native circulatory system is no longer compatible with organic blood due to the presence of high-density implants, artificial organs, or non-biological metabolic systems. Synthetic blood supports oxygen delivery, thermoregulation, and biochemical stability in augmented bodies by using nanostructured oxygen carriers, electro-buffered plasma substrates, and programmable microfibrin, all designed to interface directly with synthetic tissues and modular implants.   Its use is extremely common among Vey’Zari who have transitioned into full-body augmentation, especially elite operatives, enforcers, or long-term covert agents whose systems would reject or destabilize standard organic fluids. However, full synthetic blood replacement in unmodified or developing bodies remains rare and medically discouraged. The case of Calyra Val’Druna is the only recorded instance of such a procedure being performed on a newborn—requiring a synthetic heart implant and total blood replacement due to a congenital rhavak gene deficiency. While she survived, the intervention left her permanently infertile and dependent on lifelong recalibration therapies. Her case is considered a medical anomaly and not representative of standard synthetic blood integration. For most recipients, synthetic blood is a stable, routine adaptation essential for sustaining heavily modified physiology—not a rescue measure or emergency substitute.
