Deneo's childhood

My story takes us to a place that magic and gods and goddesses existed. Humans and elves blessed with magical powers or strong melee skills, and other noteable races such as dwarves, orcs, and ogres. My childhood was in a monk temple of the Shado Kan clan. Apparently it meant something of the arts of fighting using Shadow magic of some sorts. The only reason I landed here in my childhood is cause these damnable monks found me and my twin brother in a basket in a nearby field. Isn't that nice, I was orphaned with only a brother to share my life with in the early days.
I guess you want to know his name as it might play some role in future events. Sparrow Diante was my brother, and I am known as Deneo Diante. We were left to be found by these monks and no clue where we orginally came from. Needless to say, the masters of the manostery agreed to have us in their schooling and teachings. Sparrow seemed to absorb evrything they taught him, but I myself found it meaningless and moot to a point where they started to disgust me. Of course that disgust got on the teacher's nerves and wouldn't be long that I was whipped on a daily basis or slapped with a stick against my fore hands. Only fuel to start a fire is what it added it up to.
Even though Sparrow and I were twins, we looked nothing alike as far as our features went. He had silver white like hair and I had dark raven black hair. He was kind and good hearted, I was hardened and mean. Your basic good and evil set up.
I remeber the days when we started to pick up kendo sticks to learn the arts of melee fighting. Sparrow was quick to show everyone he learned everything there was, but I was far more advanced in training that I was easily overpowering Sparrow in our spars.
In our mid teens, our magic started to come through to us. Each of else felt a pulse of energy that was linked to us and one urge lead me to leave the monastery late one night. The moon was full, I remeber that much but I found myself walking aimlessly in a direction that seemed to pull me towards it. Then I found a cave opening, an opening I could of sworn wasn't there before. I entered into the darkness and felt a leap of energy in the form of joy sprouting over my being as if something good was about to happen.
In some sense it was good, for me. For those around me though, they would probably beg to differ, if they were alive. Inside the cave, I found a blade of the darkest onyx like coat laying peacefully on a rock like table. It was sitting there as if waiting for me. I reached my hand around the hilt of the blade and a dark aura quickly slept around my body and my eyes flared some strange crimson light into the room and then I could see... see in the dark! Darkness was no longer my enemy as I could see in the darkest of places. Darkness was becoming one with me.
It was then an evil urge came to surface. All the pain and suffering I withstood from the teaching of the monks was lapping over me like someone trying to overwhelm me in a fight. I felt anger and flashes of light sparked from my eyes as I made my way out of the cave. Energy of the magic that came to my hands and the blade in my other, I felt invinsible.
