Benedict hellrides away from the Courts of Chaos during the Battle of the Demi-Monde until he gets far enough away from the Primordial that he can shadow-walk without being sensed. He takes an indirect route and checks for tails constantly along the way until he is satisfied he is clean.
He eventually arrives at the Bogs of Gloom and pays a riverman in silver to ferry him to the Lightless Lighthouse. Once there, he stops to meditate in order to shed any last magical tailings that might be tracking him. He slows his heart. He rests his mind. He completely ceases everything until finally his magnetism is dispersed and anything following him no longer possibly could.
He restarts his heart and mind and re-enters his body. He stands, regains his composure, and sets out anew to his final destination. When he finally meets the Soul Drinker, he is ready.
“This is who I want you to kill,” he says, sliding a playing card across the table with a picture of Nyneve upon it.
The Soul Drinker touches the card and feels its energy. He gives Benedict a grave look.
Benedict gives him a look back that says ‘I didn’t come all this way to play around’.
The Soul Drinker runs his fingers along the edges of the card and drinks it in. He gives Benedict a look that says he needs to know more.
“Look,” Benedict says, understanding this to be part of the negotiation. “She’s Morgan’s daughter. She’s even a red dragon! I’ve seen it!”
The Soul Drinker nods slowly. “She is also your sister’s daughter,” his raspy voice barely whispers.
Benedict nods. “You’d never know it from the path she has chosen. I’m telling you, she is Morgan’s daughter first.”
The Soul Drinker nods slowly again. “The sins of the father are not the sins of the daughter,” he rasps.
Benedict’s face goes red. “There can be no second Morgan,” he spits. “My sister exists to counterbalance the fact that sunnuvabitch exists. When she was born celestial and beaming with light, our father knew right away that somewhere else a terror existed. Do you forget the things Morgan has done? Do you think me wrong?”
The Soul Drinker nods as he does and eventually shrugs. “It feels cosmically important that these two opposites have found each other and made this one. She represents balance.”
“She is not balance,” Benedict sneers. “She’s a goddam red dragon! She is not a healer, or an angel, or any of the things her mother was before Meat Grinder Rock.”
The Soul Drinker nods again, this time for a long time. “Killing her will devastate your sister.”
Benedict nods. “She died at Meat Grinder Rock. That motherfucker killed her too.” A tear involuntarily runs down his cheek.
Eventually the Soul Drinker nods and agrees to do it. They agree on a price and then go their separate ways.
