"QUIT"

This command will warn you, to prevent accidental quittings, and then
give you the option to quit.

When you need to go, you can leave the game with this command.
Note that quitting this way may cause any items you might be carrying to
simply be left on the ground. If you wish to have your
equipment stored, you may have to find an inn and pay rent.

You cannot quit the game if you are a murderer with a killer flag.
