What is the situation climate of 'Harry Potter and the sorcerers stone'?

Situation climate of a story means what happened before the story took place. It is part of the setting. In this case, we learn that there is a magical society of witches and wizards in England. This is secret from the mundanes or non-magical humans. At age 11, witches and wizards of England are invited to go to go to a school for wizards. The original British book was Harry Potter and the Philosopher's Stone. The Philosopher's stone was an alchemy term going back to the ancient Greek Plato.
