Ds- Whiteout

He could see the beautiful, odd-looking dragonet that would come out, and he could see the moons sharing their power with her, too.
Then they would be the same. She would be born under three moons as well. She would have the same power as him … and the same love from Mother.
Which he already had to share with the undeserving ice monster across from him.
No. This was his. All he had to do was nothing. His sister would come out in her own time, tomorrow when the moons were no longer full. Then he would be the only special one.
“All right,” said Mother. “If that egg hatches, you can name the dragonet inside. Only … remember she has to grow up in the NightWing tribe. It’ll be hard enough — just, try to be kind, is all. Think of her future and how she’ll need to fit in.”
Father nodded, seething internally at being instructed like a low-ranked dragonet in training.
She’ll be all right, Darkstalker thought. A thousand futures dropped away before him as he made his first choice. Futures where his sister joined his quest for power; futures where she fought him and stopped him; futures where they were best friends; futures where one of them killed the other, or vice versa. As Darkstalker folded his talons together, choosing to keep them still for tonight, every possible future with a thrice-moonborn sister disappeared.
He saw them blink out, and although he didn’t know exactly what it meant, he felt somehow a tiny bit safer, a tiny bit bigger and stronger.
