J'rasha wasn't always called Nightshade. Her maiden name always bothered her since her young age. She was always a bit of a special girl. She always had some deep dark desires deeply. Desires which only clenched with killing.

Even at a young age. She loved to kill the local fish and small animal population. When her fellow sisters and brothers were toyed with sticks and rocks, she already played with a stolen kitchen knife. 

Her family never liked this. They could not understand her darkest desires about killing others and taking away life.

On a stormy night she had a vision. a Dark vision where a voice called her. It was Sithis. She didn’t know who was him. But she listened as the voice just pleaded her to come closer. 

The voice said.: “Come my sweet child. Show us your greatest desires. Kill your closest friend and we will know!”

J’rasha didn't understand this when she woke up, but deep down she knew this is what she wanted. The next day everything went normally. Her family felt it unexpectedly as she spent the whole day with her friend. Until sunset when she brewed a poison from a Nightshade flower. Since this flower was her favorite flower. The colors, the look, the whole purpose of the flower.

An hour later she called her friend for a little tea party. As he sat down she smirked on him. He didn't understand and suspected anything. She used that poison on her now freshly acquired dagger and walked behind him. She hugged him and kissed his cheek. Then with a secret stab she cold bloodedly stabbed her friend. He bleeded out as she drank her tea in the chair.

The next morning they found the dead body with the wounds on it. But J'Rasha wasn't there at all anymore. The locals and her family quickly realised that the murderer was indeed her. They did not have to frame anyone. Instead of searching for her they framed her family and kicked them out from the tribe. The supporters who claimed J'Rasha is innocent were quickly outnumbered once they found the dagger in her bed. 

The next days for J’Rasha were eventful as she tried to get as far away as she could from home. She had no food, no help, just herself. The pain that killed her friend, tortured her. She could not believe she did it. She cried and mourned for her friend for days, until a shadowy figure not contacted her. 

"We know'' she said. J’Rasha was scared by her. She did not know who was and what she wanted. but the figure took off the hood and talked to her. "You have nothing to worry about my child, I'm a member of the Dark Brotherhood. You were chosen by Sithis to join us."

J’Rasha started to cry. She could not believe this was really happening. The woman sat down next to her and explained to her a little story about her first kill, that, that is always the worst. She then asked her.: 
“Wasn't this your deepest and darkest desire?”

J'Rasha hesitated to answer, but burst out a silent yes. 
The figure happily approved this. Gave her food and invited her to join on her travel to home. 

~An untold time later. 

The next years for her went quite fruitful. From a pity child murderer she became a bloodhungry predator, a cold blooded murderer. Under the years she has claimed herself a new name. Nightshade. Just like the flower.  The denizens of the den had nothing against it. 

Years later on a quite unfortunate contract she realized her family was next the target. She could not do it. She straightforwardly refused to do it. The den did not really approve of this. She instead escaped and tried to hide. Hide in her shame, in her feelings. After so many people. The first person who she could not kill was her own mother. 

After a long thoughtful thinking in her vain, leaves behind her Brotherhood. So she traveled north. north into Skyrim. Skyrim was lesser known about their brotherhood.

A weird idea came to her mind. She have decided she will try to be a mercenary. So. She has become one. Her current location is unknown. But they have seen a figure around the Nightgate inn.
