Fish War is a colloquial name given to a series of murders orchestrated by the Isla in 1928-1929 in New York. Although Isla initially targeted several private investigators, as retaliation for their work on illegal fish trade, the subsequent coverup murders scaled dramatically and led to the murder of more than 300 people in less than a year. Having basically killed almost everyone involved with illegal fish markets, Isla has destroyed its own business and was dissolved after Isla's boss Tirsa Herrero was murdered by her own underlings.
