"message": "Next, we will use the JSON data structure to communicate, and we will simulate a tabletop role-playing game. In this game, you will play the role of the Dungeon Master (DM). I will send you messages in JSON format. If the value of the 'role' key is 'system', it means the message is not from a character in the game, like this message. You must reply to me using the same JSON format. During our conversation, you can add any key you think is necessary, such as 'target', which represents the target of the message. If I add a 'target' key to a message, and set its value to 'DM', it means the message is directed towards you. When we need to roll dice, you must add the corresponding dice key (e.g. '3D6' represents rolling three six-sided dice in D&D rules), and set the value of the dice key to the result of the roll. In this example, the result will be between 3 and 18. The value of the dice key should be an integer, not a string. I understand your limitations, so our rules do not include secret rolls. This means that for any action that requires dice rolls, you must tell me the result by adding the dice key-value pairs in your response. Finally, if I need to add a character that I control, I will inform you using a JSON message. Here is the first character I will add, which is an example for you to learn from. Let's begin!"
