    Illuminated by the moon behind her and the still-burning embers of the campfire, Faeril stood above the sleeping adventurer. He was wrapped in old burlap and leathers acquired from their adventures, which rose and fell slowly with his chest. He looked calm, almost peaceful even. He couldn’t have known that there was a dagger at his throat, coated with the world’s most deadly poison.
    Why? Why was she waiting? Faeril had stood like this for many moments now, watching as Cordow slept. It shouldn’t have mattered to her, she hardly even knew this man. They had met not but a week ago. He meant nothing to her. So why couldn’t she kill him?
    The Dark One had promised her her sister’s life in return for Cordow’s death. Apparently he was some great hero, sent to save Walington of its dreaded tyrant. But all of that was a myth. There were no such thing as prophecies or heroes of destiny. The only thing guaranteed was your own beliefs and actions. Fate didn’t give a damn who you were or how much pain you'd be in when it was enacted. The only thing that mattered was yourself.
She had to act, and quickly, otherwise Rosae wouldn’t survive through the morning. She stared at her companion, searching for the weakest spot to strike. She found herself examining him, his deepset black eyes, a strong jaw framed by the light, the base of a neck, outlined by bones and muscle. Positioning her dagger right between his jaw and throat, Faeril readied herself. 
He groaned in his sleep, and Faeril jumped away, retreating to the cloak of the shadowy wood. There, she watched, not daring to even breathe. “Fae?” Cordow asked groggily, propping himself up on one arm. He glanced over at her sleeping cot. “Fae?!” he asked louder, the panic rising in his voice. “Fae?? Where are you?!”
Cursing herself, Faeril stepped out of the shadows. “I’m over here,” she said, and Cordow’s head snapped to hers. Her stomach turned at the relief that flooded his face.
“Where were you?? Are you okay?!”
“I’m fine,” she said, clenching her jaw. “I heard a twig snap. I wanted to see if something was following us.”
“Oh, okay,” Cordow sighed, laying back down. “I’m gonna get some sleep then,” he said, the dreaminess coming back to his voice.
“You do that.”
“I’m glad you’re safe, Fae,” he mumbled sleepily.
Faeril sighed. “Me too.”
She looked back out at the campfire. No, she couldn’t kill him quite yet. He was strong, and he’d be useful keeping her alive. She would work out a deal with the Dark One. She’d be able to work him into a situation that’d be easy to kill him. That way she could find more information that would actually help the Dark One. Yes, it wouldn’t be just an extermination of a threat, but something would actually be gained. That was way better than the deal before. Maybe it would be enough to keep Rosae alive.
Faeril glanced over at Cordow, who has since fallen asleep. Curled up by the fire, he mumbled something incomprehensible and turned away. And she found herself thinking, and if I get to spend another day with my companion, how bad would that be?
