If you look to either side upon entering, you will see a modern operating room through a glass door. The farther you walk, the older the equipment will get, the more old fashioned the doctors will be dressed. As you can finally see the end of the hallway, the screams of the patients will be nearly deafening. The hall will terminate in an open door leading to a single wooden table, a man in woolen medical clothing, stained brown from blood, will be bent over a corpse. The body's face will be covered, and the man will turn silently, screwing the top onto a cloudy jar of liquid, filled to the brim. He will hand this abnormally heavy object to you, before turning back to his work. Instantly, you will be outside of those cast iron gates.
From that point on, disease and injury will never affect you, but if you ever open that cloudy jar and pull out the contents... you will find a heart, pulsing and beating loudly in your palm. A sudden feeling of horror and revulsion will pass through you as realization strikes, that you have just pulled your own living heart from your chest.
