The Stitch Network is an underground medical service of approximately 200 volunteer medical professionals — doctors, nurses, paramedics, surgeons, and BCI technicians — who provide free or low-cost medical care to GLMZ residents who can't access corporate healthcare. In a city where medical care is tied to corporate employment and insurance, the Stitch fills the gap for the unemployed, the undocumented, the criminal, and the simply too poor.

The Network operates from hidden clinics throughout the Shelf and Underworld — spaces that range from well-equipped surgical suites to converted apartments with basic first-aid capability. Volunteers include licensed professionals who donate hours outside their corporate jobs (risking termination if discovered), retired medical workers, and self-taught practitioners whose skills have been honed by necessity. The quality of care varies, but the Network's best clinics provide treatment that rivals corporate facilities.

The Stitch is strictly neutral — they treat anyone, including corporate security officers injured in off-duty incidents, gang members wounded in territorial disputes, and fugitives on the run. This neutrality is maintained through a simple rule: what happens in the clinic stays in the clinic. No one is reported. No one is turned away. The Stitch has become one of the few truly trusted institutions in the Shelf, and its clinics function as de facto safe spaces in neighborhoods where safety is otherwise nonexistent.
