Sector Twelve General Hospital

Sector Twelve General Hospital was a gigantic multi-species hospital space station built in open space in Galactic Sector Twelve, founded as a peace-promoting project by two heroes from opposite sides of humanity's only full interstellar war. ("Accident")

It accommodated patients and staff from numerous different species, with different environmental requirements, behaviors and ailments, but also patients that the builders never anticipated. The Galactic Federation eventually decided that the emergency service the hospital offered to victims of space accidents and planetary catastrophes was its most effective means of making peaceful contact with new spacefaring species, giving Sector General an even more important role.
