Would be a perfect name for a prog group!
Despite being grown with care and affection in the Iron Tree Tribe, Silk became a terrible person, because sometimes people are like this.
She used to be filled with a sense of rage, greed, a thirst for recognition that only submitting, smothering, hurting could quench. Her tribe, and her mother expecially, would have never let her go with her murdering hunger, not even out of affection, so she had to flee.

At some point in her wandering, she met a small group of animals, lead by a little, short legged dog named Black Jack. They were a little happy tribe of sociopaths, that traveled the City through unknown paths, mostly underground through pipeworks, waterworks and sewers, and hunted and ate people.

You can eat meat in the Big City, but all of it comes from The Forest, the outside, infinite wilderness surrounding it. In the Forest, you become an animal, hunt is free from hate, from rage, it's just, running and chasing (https://www.furaffinity.net/view/33593048/)
But that's not what The Puppies liked, they loved to taste fear and pain, from people that could actually realize that they were going to be slain. That kind of pleasure for violence and abuse that could fill their hunger... for a little while. Because if you're like this, you're never satisfied for long.

Black Jack had a weapon, a Cambion, that is the offspring of a spirit and a demon (see also: https://www.furaffinity.net/view/44933490/). A big dog, apparently blind and deaf, having no eyes and ears, but able to scan things with two long insect antennae. The Cambion had no name, and nobody ever knew when and  where Black Jack had met him. He had developed a language to communicate with him, composed of clicks and whirrs, and scents, that he captured from dead bodies on small sigils made of wax. And whit this, he had the Cambion kill and maim at his command. 

The othe two were a cute little bitch named Candy, and a big friendly cat named Charlie. Both as nice and funny as much as they were depraved and murderous.

Silk managed to become Jack lover, and raided the City with the Puppies for some happy years. The day they killed and ate terrified innocents, the night she had the worst nightmares of lives spent in cruelty and violence, as Spirits' dreams are whole lives spent in happiness or anguish, depending on their karma. And Silk's karma was not exactly spotless. This only made her angrier and greedier.

At some point, Silk was able to learn Jack language and used The Cambion to murder him, being tired to be the Boss' Babe, and just wanting to be the Boss. 

Until Candy and Charlie killed the Cambion and her and started a whole new band, but this is another story, for another time.
