Harry Potter and the Call for Help

Disclaimer: I own nothing except what is new.

Summary: AU What if after Sirius died in the DOM and Harry learnt the prophesy, the pain got too much for Harry to handle? What if he remembered a ritual he read about in the library while trying to forget the pain for a few moments? What if he decided to do the ritual with interesting results? HPCharmed crossover

Chapter One: The Charmed What and the Boy-Who-Summoned-Them

(Hogwarts's Library Midnight Day Students leave)

Harry Potter sat at a table that was overflowing with books about alternate forms of magic or magical abilities.

"There must be something in here about the power he knows not. This is pointless there is no way I can beat him he has knowledge of magic that even Dumbledore doesn't know, he has fifty years on me and its not like I have an army to back me up. AHHHHHHH." Harry screams as he gets hit over the head by a large book.

"What loosing Sirius wasn't enough for you? You had to have a book fall on my head? What's in here anyways I've never seen this book before?" Harry says while looking at the book in his hand noticing the name 'Magic of Dire Need'.

"Well it doesn't get much more dire lets see…This might actually work!" Harry says quietly before putting the book in his bag under all his other books.

(Number 4 Private Drive one week later)

Harry is lying in bed thrashing in his sleep from an nightmare of some sort. Harry all of a sudden jumps up in bed before calming down.

"I can't take this anymore I have to do something. Maybe that ritual in the book." Harry says as he puts on his glasses and goes to his trunk to remove the book.

"Let's see according to this I need to have five candles set up as a pentagram, with a circle of salt outside of it. Then I'm supposed to stand in the middle and say a rhyme that expresses what you want and call the spirits of my dead ancestors after cutting your finger with a silver knife. Lets start with the rhyme lets see."

---------------------------------------------------------------------------------------------------------------------------

(Two days later)

"Candles in perfect pentagram check, circle of salt check, stupid and annoying to make rhyme check lets go."

Harry went to the center of the circle and pentagram and cut his finger to the point where blood was coming out but it was not life threatening.

"Spirits from near and far

To me do I call,

Ancestors of Blood mine

To stop my fall,

I summon those

Of power three,

To protect the line

And to comfort me."
