When you create your Wizarding World identity, you can either create a fact file, or write a story.

If you're creating a fact file have at least these things:

Name:
House:
Wand (wood and core):
Patronus:
Blood Status:
Year at Hogwarts:


You can also have

Special Ability (e.g. Metamorphmagus, Animagus, Legilimens):
Pet(s):
Quidditch Position:
Quidditch Team (not the Hogwarts Teams):
Favorite Character:
Favorite Harry Potter book:
Favorite Hogwarts Subject:



If you want to have a more complicated fact file, then do that, but then also write a paragraph or two about your backstory and such.



I hope this was helpful!
