A few days after the dementors attack Harry and his cousin Dudley, we find the young wizard laying on his small bed thinking about his upcoming hearing. He was about to go to sleep when he hears pecking at his window he gets out of bed and opens the window to see Pig with two letters so he tries and catch Pig to read the letters. He catches Pig and gets the letters.
"I guess Ron and Hermione decided to write Hedwig" he said as the snowy owl hooted in response. Opening the letter from Hermione to see that it is blank then notices the other letters says open me first. He opens the letter to see its from Sirius instead of Ron.
Dear Pup,
There has been a lot that has been kept from you which I will explain to you when I see you in person. The other letter is from someone you trust read the letter and have an open about what it says.
Sirius
P.S. touch wand to the letter think map.
Harry grabs the blank touches his wand to it and says "I solemnly swear I'm up to no good" the letter started to fill with ink which became words. He started to read the letter.
Dear Harry
Dumbledore has lied to you the Dursleys are not your family; I repeat not your family. The Weasleys are not your friends except Ginny and only Ginny, I will explain about her later. But Gryffindors are not told but all fifteen year old wizards/witches go through gating which is when their magic chose their alignment and the type of spells used. Hogwarts does gating for its fifth years three days before September 1st but you're not told unless you're pureblood and that's because you know and most half bloods know as well. Also I'm Hermione but Hermione Jean Granger has never existed I'm actually Cassiopeia Dorea Black-Potter your twin sister I explain the rest later but read the attached note you need the family book.
Love
Cassiopeia Dorea Black-Potter
Ancient and Noble House of Potter
Harry sat confused when he read the note he understood he needed to call the family grimoire.
"Interesting Mione and helpful"
"I Hadrian James Potter call on my family, my blood to show me my heritage, my magic. I call forth the Potter Grimoire!" a flash of red appeared and a book appeared on the night stand Harry picked it up saw two crest on the cover turns the book to see the binding to see his name on the binding Hadrian James Black-Potter. Hermione and Sirius want him to learn family magic to protect himself and that's what he is going to do. He open the book its says an heir who knows most of their magic by the Gating will be called a scion or Lord/Lady officially to the public instead of mister/miss. He turned the page to see what would make him faint.
