If you didn’t know, I write Mary Sue fiction as a hobby.
Most of it is found on my tumblr.
But anyway, I have this story called The Demon in The Ring.
In said story, there is a demon character named Alewar. (Also mentioned in my other story, The School of Magic.)
His name means “Guardian/Protector” in some middle-eastern language.
I made a song for him.
TL;DR: This is a character theme.
