Hey guys, Star here! And I'm just gonna leave a little topic.
The favorite pony I like is Luna, after she turned evil, Fear and Hatred was in her. But then Celestia was talking about the Crystal Empire to Twilight, and when King Sombra got fear and hatred in the crystal heart, so.. maybe the effect of fear and hatred in the crystal heart could have a effected Luna and made her tranform into Nightmare Moon. Cause.. they were both gone for 1,000 years. And that kept me wondering for a while.
