[@candlelitcraft] I do mot want any electronic devices within Hogwarts. We Will stay with that. No electricity in the castle.

You can pass ny canon characters and talk about them with others, mention them in your posts. However, you shouldn't engage with them. Our story is taking part away from what they are doing. We would basically be "statists" in their story and that's what they are in our story. They exist, but they are not part od our story.

The staff of the school will be discussed between the GMs. Dont worry, before entering the castle you should know the staff lost and if canon character's characters are on it, how you can interact with them.
