The Chaotic War Goiás (CWG) was a brutal and violent event that took place on December 16, 2025, in Shadow Universes. This event was marked by the gruesome torture, dismemberment, and mutilation of Costelinha (Heully Rios Santos) and his entire gang of drug dealers and traffickers by the ISG serial killers and vigilantes, including Tiago Henrique, José Vicente, Aline Duarte, and Thamires Vega. This act of vigilantism was a stark reminder of the ISG Supergroups' superiority over both the police and criminal elements, a power dynamic that had been evident since 2023. Heully had previously been jailed in 2016 for 20 homicides in the Aparecida de Goiânia and other diverse crimes. The ISG gathers equal admiration, fear and sparked debates.
