Chapter 1
The spell - Part1
I had been working for hours, days, weeks but nothing. I was nowhere near my goal.
It all started when I married Potter just after graduation. My family had made a marriage contract with the Potters. I had always believed that I was a muggleborn. It seems that my family was from a long line of squibs. Even my mother did not know that. My parents were shocked when gringotts informed them of the contract. I hoped that I would grow to love him.
The first few months I was happy. I really thought I could make her marriage work. But potter changed, he had become unbearable. When I asked about it, he told here about the prophecy. He believed that he would be the one to kill Voldemort. Though he satisfied the prophecy's requirements, I always thought the prophecy to be too vague. I could think of 100s of people who have been affected by Voldemort. The mark of Voldemort could easily mean an emotional scar. It was well known that he was a very powerful wizard. But I don't believe him to be Voldemort's match. Potter told me that Dumbledore told him that the power Voldemort know not is love. I don't believe Dumbledore. I think Dumbledore has his own agenda.
We had to hide from Voldemort so that Potter could train. I was bored to say the least. I started my own training; I was not the smartest witch in Hogwarts for nothing. Potter underwent auror training learning spells that won't even tickle Voldy. I started learning old magic; while useless in dueling it could very well save my life. I was not trying to out duel Voldy, I was trying to outsmart him. Voldy was probably the best in the dark arts while Dumbly was the best in Light magic. Potter was following Dumbly's foot steps to become the next light lord. It was useless to fight the night with a torch, even the sun casts shadows.
I was studying both the light arts and the dart arts. I had realized that one cannot survive without the other. Moreover the ministry's definition of the dark arts was based on what those inbred weak dinosaurs were able to cast. Mark my words in a few decades the Patronus would be called dark arts.
I had recently learnt that I am pregnant. I wanted my baby to grow in a world free of manipulative Dumbledores, evil Voldemorts or idiotic Fudges. I will make sure of that even if I have to sacrifice myself or my husband for it. That brings us to my goal, the wonder spell of salvation. I was working on a spell that would basically render the Killing curse useless.
I had the basic spell working. It is based on the theory that magic is a type of energy. The spells are different frequencies of that energy. The protego and other shields are based on the concept of Superposition (See author's note 1). Some how the unforgivable curses don't follow this rule. I believe this is because they contain energies of multiple frequencies. The shields just stops one frequency, the rest go through the shield.
My spell is based on the conservation of energy theory (See author's note 2). All the powerful and wise wizards and witches of the world don't even know of this. Even Dumbledore who was supposed to be a Muggle lover, didn't care about Muggle physics. I was thanking my stars for my Muggle education.
As I said my spell is supposed to convert the energy of the AK into anything the caster wants. It could be anything from a simple stupefy to a duplication spell. But the AK or the converted energy will always hit its mark. I guess being stupefied is better than being killed.
Right now my problem was the no of options available for me where limited. The stupefy conversion was too powerful; the person hit by it goes into coma. The duplication conversion creates too many copies and none of the copies could cast magic. It was frustrating.
Author's notes:
-------------------
1. Superposition: When the two waves are 180° out-of-phase with each other they cancel, and when they are in-phase with each other they add together.
2. Conservation of energy: Conservation of energy states that the total amount of energy in an isolated system remains constant. In other words, energy can be converted from one form to another, but it cannot be created or destroyed.
