The one thing that utterly impresses me every time, especially when I go on Tumblr is the amount of people who have come up with extensive back stories for characters or places inside the Potter World. The stories or even the fan fiction that has come out of this series completely astounds me. It just shows the dedication and pure love us readers and fans have for this series. Pottermore also gives us fans even more opportunity to delve into the world of Harry Potter and being sorted into a house as well as reading histories about wands, other wizarding schools, history of locations and history of other characters, among so much more. It creates this world that allows the reader to imagine that it actually exists. Sometimes people need that; they need that world to escape to and live inside of because they believe their world isn't magical enough.
Tumblr has amazing stories as well as gifsets that are just extraordinary. There is one blog that I absolutely love as it has a lot of different back stories for other wizarding schools around the world (and not just the new ones JK added to Pottermore). Take a look:
We, as a generation, have fallen in love with this story. To the point where we could not even imagine our lives without this series. Even though the books and the movies have ended the story continues to live on in the people it has enlightened.
