Down below the big city, in the old abandoned tunnels a lone being was walking. She was carrying a big battery with her mouth. The battery was connected with her chest via two red and black wires. One of her legs being differently colored than the others. Purple streaks behind her eyes and a jagged mark on her neck. Her eyes were glowing in the dark as she made her way through the tunnels.Looking here and there. She was clearly looking for something. She sets the battery down and looks around.
 
“I have a good feeling about today. The last few days were not really good to me, but I’m sure that I’ll find some new parts I can sell today.”  
She must be a Scavenger. Looking for lost parts under the city. Selling them to others.  
She picks the battery up again and keeps wandering. She looks around a corner.  
“Maybe even a…wha?”  
Her eyes widen in shock, she almost drops her battery as she spots something.  
“I… c-can’t believe it! Could it really be!?”  
She has found something. It must be really valuable to her.
