At an underground bar, Cyanide—under the guise of a bartender—is a poison dealer. His job involves selling deadly toxins to wealthy clients. He has a range of poisons in store, such as those that require several doses and don’t have an immediate effect. There are also deadly, odorless poisons that work like a charm. Cyanide is critical of who he makes a transaction with, even incorporating a background check. While some poisons have an antidote, it comes with additional fees.
