Glados was a spy employed by France. She took 10 years of Medical School, earning her a medical license and lots of knowledge in the art. She has never failed any operation, no matter the conditions. She carries only a single 3 barrel revolver, which she barely uses. She usually only sneaks behind enemy lines to listen on secret meetings, and occosionally impersonate someone to do so. She was (supposedly) caught spying on a Spanish war meeting and executed at the age of 42.
