Grand Master Crawford Starrick hand-picked Cletus Strain to be one of the seven leaders of the Blighters, a street gang that dominated the streets of London. Strain was given control of the Lambeth borough after he was trained by Maxwell Roth.
He became known for his theatrics, often using smoke to incapacitate his enemies, as well as the fact he always made time to play games.
When the twin Assassins Jacob and Evie Frye arrived in London in 1868, they started working with Henry Green to diminish Templar control in London. Their gang, the Rooks, soon challenged the Lambeth Blighters to a gang war, during which Strain was killed by one of the Assassins.
