Hi! Before we start our plot, story, and so on, let's tell you about yourself:

1. first name (last name/family/genus)
2. age (also course: 1st year (11-12 years old) 2nd year (12-13), 3rd year (14), 4th year (15-16), 5th year (16), 6th year (17), 7th year (18).
3. faculty (Gryffindor/Hufflepuff/Ravenclaw/Slytherin).
4. appearance (you can describe the appearance with different years, well, from the beginning to the future).
5. personality/behavior.
6. relationships (with characters. If you want).
7. Pureblood/The half-breed/Muggle?
8. Patronus (optional)
9. Bogart (optional)
10. the facts (well, the most diverse. Whatever you would like).

So, here you can come up with anything you want, absolutely anything. Just write me a story or something like that, and I'll be happy to continue, or warn me exactly what I should do. Well... good luck!
