"I thought defcon 5 was an army?" Phineas asked the elf

"It is but I am here first" the elf said " Go back the way you came and go to the left"

"Tell me elf,what is actually that way" Phineas asked

"As you are family I may answer that question" the elf said " That is memory's of Chaz's troubled childhood and school life"

"Oh right" Gilderoy said,this time he doesn't smile " Let's leave" he turned away from the elf and began to walk off. Phineas caught up to him and asked

"Do you know what that was all about?"

"Not in full details,no" Gilderoy said " But I am aware of some aspects of Chaz's past. The one that knows the most would be Grindelwald,he knows more than Dumbledore does,well apart from her father"

Phineas turned and looked back to where the elf is still stood and noticed that the sky was actually darker behind him. The Slytherin headmaster had to admit that he is rather intrigued by what memories are back there,but he said to his granddaughter that he would stick to where he is meant to go and nothing more. Phineas turned back and continued on after Gilderoy. The pair soon returning the place they had arrived,and this time going to the left. It didn't take them long to come across doors,that held recent memories. As a helpful sing had told them and all they had to do know was locate the one about the moment Chaz opened the book and see what actual happens.

They reached the door and opened it,the two stand and watch as Chaz is talking to the teachers and then her two friends join them. One of the hands the book to Chaz and she then opens it too the middle of the book. It was then that Phineas saw the pages of the book,and there indeed was something about the Black family on the pages. On the left was the Black family tree and on the right was some writing, possibly written in French. Then a white light comes from the book and the memory ends. And Phineas and Gilderoy are back in the headmaster office 

"So what did you learn?"
