Zeythrine Accumulation Disorder

Zeythrine Accumulation Disorder (ZAD) is a foodborne metabolic condition specific to the Vey’Zari species, triggered by prolonged or high-volume consumption of zeythrine-bonded proteins—a class of nutrient-binding compounds found in industrial food rations, counterfeit nutrient bars, and certain black-market meat substitutes common in Thauzuno’s lower sectors. Zeythrine compounds are engineered to extend shelf life and simulate muscle texture in synthetic food, but in Vey’Zari biology, they bind aggressively to neural microelectrolytes and interfere with synaptic reuptake channels. Over time, this leads to toxic buildup in the prefrontal and motor cortices.   Early symptoms include sluggish reflexes, stuttered speech response, and hypersalivation. As the condition progresses, affected individuals experience executive function breakdowns—difficulty making decisions, slowed tactical parsing, and misfiring memory recall. In severe untreated cases, ZAD can lead to full neural feedback loops, resulting in temporary motor paralysis or combat inoperability. Treatment involves a strict detox regimen using enzyme-saturated chelators and high-flux neurodialysis. The condition is reversible if caught early, but repeated exposure results in permanent microstructural damage. Consumption of zeythrine-rich food is banned in regulated syndicate zones, but it remains widespread among scavengers, undercity freelancers, and poorly monitored augmentation camps. Among enforcers, the phrase “he’s gone zeythrine” is shorthand for tactical unreliability caused by low-grade rationing.
