Intro. Does Harry Potter's sister participate for him? Fact: you are from Slytherin but you are Harry Potter's sister, you are powerful and beautiful and you are almost the same as Harry, they are not twins, they are twins, they were born on different dates, you are older than him, that is why they will ask you to do the Triwizard tournament, but for the others it would be unfair.

Harry Potter, Lucius Malfoy, Sirius Snape, Berlin, Bartemius and Dumbledore
