This was made by my Friend and D&D buddy Senpai Satan. Spring Glow is a Kirin in the Fallout Equestria Universe. A survivor from before the bombs that somehow survived in her Stable 8. Having no memory of what happened she travels the wasteland.

The story behind this is that either trough tests done on her in the Stable or just because we thought the idea of different Kirin forms due to other emotions. She literally wears her emotions on her mane.

While I don’t have a image source I do have a Deviantart to point to in general: https://www.deviantart.com/senpai-satan
