*The ordinary key fits Mordred's underground laboratory. To get the key to Mordred's lab:
In More Detail
You have to do some things before you actually get the key.
1) You have to get the "new password". Go to the castle and go inside the door on the left. the princess's servant girl will be in there. Talk to her and say "Where did you take the messages?" she will say that she put them in the fountain in main street. She put them there because the order (that the princess is secretly a member of) needs info from her.
2) Walk to the right of the room and get the paper. It says that The order needs to change their password because the princess is afraid that her mom and dad will find out what they are doing and stop it.
3) Go to the old Mille and talk to the girl with pale skin who is dressed in almost ALL black. Talk to her. She will say, "tell me your secret, and I'll tell you mine." after she says that, you give the paper you just collected to her. She gives you the "new password". It's actually a picture of a crescent moon, Saturn, and then a star.
4) Go to the fountain in main street. Click on the picture of the solar system. Then click on the moon, then Saturn, then the star, then the sun. The picture of the solar system will then open. Go inside.
5) The people inside this room are the people of The Order. Notice that the necklaces they are wearing are the same as the girl with all the black clothes on! These necklaces mean they are part of The Order. Talk to the people there until you find the one that has the key.
