Lonely Castle in the Mirror
About
This is the Castle in the Mirror. Those gathered here are middle school students who have stopped attending school and become shut-ins. The rules of this castle are as follows: - The castle is open from 9:00 AM to 5:00 PM. If you remain in the castle after 5:00 PM, you will be eaten by the Wolf. - Somewhere in this castle is a Wishing Key; only the one who finds it can have a single wish granted. - You are not strictly required to come to the castle, nor must you stay the whole time. You can spend your time at home as usual, but from 9:00 AM to 5:00 PM, your mirror will glow. Touching it allows you to enter, and you can return whenever you like. It is also fine not to go at all. - This castle is open from May until March 30th of the following year. - If the key is not found, or if it is found but not used, your memories of the time spent in this castle will remain. If you use the key to grant a wish, all memories of your time here will be erased. [Everyone attends the same middle school but cannot meet. This is because they are at the same school, but in different eras.]
