Erin Blake, better known within ISG circles by her moniker “Cyanide,” stands as one of the group’s most enigmatic and venomous figures. A woman consumed by melancholia and volatile rage, she channels her emotional decay into acts of calculated cruelty. Her methods of killing are as personal as they are symbolic — poisoning to mirror her slow emotional corrosion, trampling to assert domination, and hemotophilic tortures to satisfy her fascination with the life force itself. Once imprisoned for a chain of high-profile murders, Blake orchestrated a violent escape that left several guards dead, their bodies later found bearing her signature toxic marks. Since then, she has lived among a secretive faction within the ISG Supergroups.
