WIZARD GUIDE
Non-Magical people, or humans who don't have any magic in their blood are known as Muggles, to wizards and witches. Muggles is just a name for regular people.
Magical Objects may move, amazingly, because they are either bewitched or made to move. Images can also move like in books and newspapers. The paintings in Hogwarts can also move and talk as well. Very interesting...
The Triwizard Tournament is very similar to the Olympic Games, except for one differene; the Tournament is for wizards and witches while the Olympics are for Muggles. Plus, the number of people involved in each event is different. The Tournament only allows three people and the Olympics allow at least two-hundred competitors. The competitions, which take place in the Tournament revolve around three tasks and the Olympics have a large amount to be completed.
The Magical World can be visible to a wizard's eye, but invisible to a Muggle. Why? To protect the wizards and witches of the world from any "harm" that Muggles could cause. A wizard building, like Gringotts bank, could be seen between a regular Muggle building, by a wizards eye, but is of course invisible to others.
Much like the Muggle world, along with Hogwarts, there are other magical schools. beauxbatons and Durmstrang for example are other wizarding schools.
Lots and lots of history are also involved within the wizard world. Rebellions, battles, events, etc.
