Looks:

Glory, in my headcanon, looks relatively the same as she does in the original books, though her neck is longer and her frills are pointer than a normal RainWing's frills. She also has sharpened claws from her time underground in the cave.

Sexuality:

I believe that Glory is demisexual. For those who don't know, this is when you don't feel any romantic attraction to a person unless you have an emotional bond with them for a long time beforehand.

Voice:

Kiara / The Lion King 2

(Once again, sorry about the long pause before anyone speaks in the video)

Other Headcanons:

Glory teaches a venom spitting class in her free time. She also teaches dragonets how to avoid venom, spit it, and not to spit it at anyone.
