Nyx

“We all born into our own natures," she said. "I, created from Chaos, was given unto the night. It is what I am. Who are you, Nico di Angelo?"
He gasped softly. "How-?"
"How do I know your name?" Nyx feigned outrage. "We are in Tartarus, you silly child. Everything here is stripped to its truest, rawest form. The longer you remain with me, the more clearly I can see you... and the less you can hide."
She brought Nico so close he thought he would pitch forward into the void of her face.
"Have you ever looked at yourself, Nico? Because I see the truth. You belong down here in the darkness. It is your nature, and yet you fight it every day. Must you be so obstinate? Must you ignore the obvious?"
"No," he said, squirming against Nyx's hold. "I know where I'm supposed to be."
A terrible laughter echoed from the empty space where her mouth should have been. "You are hopelessly confused. Those are confused end up with me."
"They do," said Hypnos. "They always do."
"Night is when all beings stumble and go astray," Nyx said, her voice now soothing, "but it is alsso when you can face the darkest truth. You must stop entertaining this notion that you can escape who you are. I will help you choose, Nico di Angelo. I will make things so much simpler... Choose.”
