Reaper

The guardian flew frantically out of the forest, gashes across her forehead and wings bleeding. Panting, she zipped across the sky, searching for somewhere to hide. Glancing around in panic, she spotted a cave in the mountains. She dove in as fast as she could, and covered up the opening with large stones that only a guardian could lift. Collapsing on the ground from exhaustion, she sighed in relief. That murdering dragon could never reach her now. Just as she let her guard down, she heard a rustle behind her. Her head snapped to the back of the cave, but it was just a leaf. Relieved, she laughed softly. She turned back around, only to find herself staring into the face of a black dragon covered with ebony armor, smiling menacingly. Then everything went black.

As Reaper flew back into her home lair, she stopped to wash the blood off of her armor and claws. As she rested, she heard something strange. Tensing up, she listened carefully and then lashed out her claws at the sound. She heard a scream, and then a thud. Looking over to where she had clawed, she saw a large dragon laying in a pool of blood. She sighed sadly. Because she was the best and most infamous assassin in the world, many dragons tried to kill her to claim the same title. Though it did not affect her at all when she killed, but she couldn't say she particularly enjoyed it.

Eventually, Reaper made it back to her lair, and went to find her nest. Seeing the blood on her claws, many dragons backed away with an expression of fear on her face. It saddened her to see dragons scared of her, as she would never hurt someone unless they threatened the lives of other dragons, but she had to shut off her emotions. After all, you don't become the most skilled assassin in the world from showing everything that you feel.
