Crisis Aid and Intervention

The Sentinels' original contract with the City of Chicago set the template for Crisis Aid and Intervention teams, which make contracts with municipalities much like private security companies and emergency service providers. CAI franchises, like the Sentinels, Guardians and Knights are extremely popular with state and local governments because they guarantee uniform standards.

They are popular with superheroes because they act collectively to provide legal and insurances services, as well as collective bargaining support. CAI teams are certified through their agencies, but still need licenses issued by state governments and are always subject to jurisdiction requirements.

The Guardians are one of the largest CAI franchises in the US, with teams in most states. The other seven CAI teams in Chicago are all Guardian teams, named for their districts (South Side Guardians, West Side Guardians, etc.).

They, and the Sentinels, are all coordinated through the city's Dispatch Department in The Dome, under the direction of the Sentinels and city coordinators. They make up two of the top three CAI franchises in the US, with the third being the Knights.
