Ok, you asked how I became what I am...
Here is my story. Sit down....

I was about 6 years old, my daddy and mum died by the defias brotherhood.
I hid myself in a old wardrobe under a pile of old clothes.
I heard them searching for me, but they didn't find me.... I stay there for hours until it gets dark outside. I crawl out of my hideout, saw my parents dead in the kitchen and ran out into the dark night.
I ran until my lungs felt like burning ice and I collapsed somewhere in a dark forest and felt into a deep sleep with nightmares.
After hours I woke up ... my legs hurt. I was thirsty and I had no idea where I am.
I walked through the endless forest, until I found a small well. I drunk a lot of water, and when I stand up I scratched my left arm on a thorn bush. Damned that hurt ... more than normal. I wandered around in hope to find a village or house... but there was nothing. Meanwhile my arm starts hurting more an more and I felt like drunken. Visions began to flicker in my head and everything starts turning.... I let me drop on an old treestump. I don't know how long I sat there... I felt sick and fell into a sleep with bad nightmares again.
The next thing I remember is, I woke up in a bed. Next to me was a woman holding my hand. She asked me how I feel. Better... she told me I was feverish for 7 days and her husband is out to figure out what kind of curse he found while he investigated me.
After 2 days he came back.
Bad news, it's the worgen curse. Were you bitten by a huge wulf or something like that?
No, but I scratched my arm on a bush.
After a few hours a old man came and started a investigation... He asked a lot of questions, studied my blood...
After a few hours he said: Good news, she will be fine with that curse. A direct bite is much more worse. It seems to be a weaker curse. She will stay clear minded without a ritual.
I lived for many years with my new parents but I felt driven by a inner beast that shouts for revenge.
When I was 18 I went out at the evening to buy some fish at the market.
At half way on a dark corner I heard three guys talking about something strange.
I crept closer ... and heard them talking about a raid planed in two days on a farm.
I stepped on a dry twig... and they turned around. Hey, who is there? Awwww a little girl, wrong time, wrong place...
They pulled out knifes and came to catch me. I felt panic... In that moment I felt pain and burning rage a for a few seconds it was dark around me.
When I was clear minded I saw the three guys standing in front of me. I jumped towards the left one and punched him into his face and scratched over his belly. Blood splattered around and he goes to the ground. I turned around and swiped the knife of the second one away and bite deep into his arm. I heard bones crushing and blood dripped all over me.
He screams loud, and I graped his throat with my claws and tear it out.
The third guy ran away, but I was much faster. I jumped on his back and took his head and turned it completly around with a loud noise.
I went back to the first guy... there lay something shiny on the ground. I took it.... and I felt a cold shiver running down my neck. It was the necklace of my mother.
That monsters killed my parents years ago... now I had my revenge.
It felt good, but I was surprised how easily I killed that three strong guys.
I sat down and the very first time I realized I'm not weak anymore. I looked down to where my feet are... 2 paws with claws... long legs... my hands are bloody...
I was surprised and shocked.
I ran home... at the frontdoor I realized I lost most of my clothes. No wonder, I was greater and got new sizes...
I get in... my mother turned around and her plate she was holding dropped down.
Oooohhh myy gooood help!!!
Hey mother, I'm your stepdoughter.
Hey ... what happen to you?
I told her the story and showed her the necklace of my mother.
I lived for 2 more years at my parents... at 20 I left to discover the world.
Everytime I turned into a worgen it felt better and better. Strong muscles, elegant curves... I could jump 3m high and running faster than all around me. So I decided to keep it. And the feelings are strong... and I started to discover the indecent things. It feels good to ...
Awww well, that was my story....
