Jiānyù

The one and only jailhouse. It's rather small, probably due to the fact that most criminals are simply executed, but it does maintain a relatively high population of a couple of hundred prisoners. Most who are sent to Jiānyù die there, for one reason or another. Rumors of scientific experimentation on patients float about. Those who do manage to survive the prison life and serve out their sentence come out raving mad, probably a result of years in solitary confinement. They are usually then killed out of mercy or sent to a mental hospital.
