Switchblade Alley is a street gang of about 75 members that controls a three-block stretch of the mid-Shelf known colloquially as 'the Alley' — a narrow corridor of residential towers, street vendors, and small businesses squeezed between two larger factions' territories. The gang is named for its signature weapon and for the physical space it occupies: a literal alley, technically Maintenance Corridor 7-G, that serves as the gang's unofficial headquarters, meeting space, and court of law.

The gang is young — most members are between fifteen and twenty-five — and its concerns are immediate and local. They don't traffic drugs on a meaningful scale (though members use and sell small quantities). They don't run sophisticated criminal operations. They tax street vendors, shake down commuters passing through their territory, steal from people who look like they can afford it, and occasionally hire out as muscle for larger organizations. Their primary function is simply to exist: to be a visible, armed presence that claims a space and defends it against anyone who tries to take it.

What makes Switchblade Alley worth noting is their code. The gang has rules — unwritten but strictly enforced — that distinguish it from the random violence that characterizes some Shelf gangs. They don't hurt children. They don't rob people who live in the Alley (residents are 'family'). They don't work with the Skinners (the cyberware chop shop gang's methods disgust them). And they enforce a peace within their territory that is, by Shelf standards, remarkably effective. The Alley is safer than the blocks around it, not despite the gang but because of it.
