Fern

“Go for the kill!”
Fang gulped hard and darted forward, slashing at the prey animal as she had been taught. She screwed her eyes shut as her strike impacted.
“Sloppy!” The older dragon’s voice called out behind her. She opened her eyes to see messy gouges across its neck. It was dead but she had made a real mess of it. Like usual. She turned away, earning an angry hiss from her mentor. She looked up at him and mumbled, “I didn't mean to.”
“No excuses!” He snarled, “It's cruel and wasteful; a hunter can't kill like this!”
She looked down, shame washing through her in waves. Without looking up, she whispered hoarsely, “Maybe I could try fishing again?”
He snorted, “Ah yes so you can splash about and scare off all the fish? Or maybe mince them up nice and fine right into the ground when you go for the killing blow?” His lip curled.
She wilted, crouching low to the ground under his sarcastic, biting words. She searched for any other use she could have. Nothing came to mind. She looked up to him, hoping he would have some idea.
He had been so kind at first, saying it was natural to be bad at first. But as she grown and practiced and still not improved, his patience had grown thin with her. Now he snapped at every mistake; there were no new successes to earn any praise.
“Let's go home,” he growled gruffly, turning with fluid ease. He leapt into the air and left her there, likely expecting her to follow.
She didn't move right away. She turned to the mangled carcass and picked at it a little. She may as well eat it. Its scent would have scared everything else in the area away if their snarls hadn't; scents also lasted much longer.
She knew everything there was to know about hunting it seemed. Prey behaviour, killing forms and pack formations, it all was near instinct by now. When it came to execution, however, she was a failure. She just didn't have the heart to end a life so close and personal like that.
She had considered magic, but not many dragons here were adept at it. Not for the first time, she considered leaving. Other clans had magic users, surely one would be willing to teach her. She now considered whether or not to tell anyone. She decided her disappearance would be curious, but not an undue stress. Her mentor for one would certainly be happier.
She would need a new name; Fang just didn't fit right. She looked around for inspiration. The tip of her tail caught her eyes and they trailed up along her body. Fern. That would be her name now.
With a powerful leap, Fern took to the air, directing herself away from her clans lair and towards the unknown lands beyond.
