Most ponies are clearly one race, but occasionally, a pony is born into two at a time.
Obsidian Crystal, the horned pegasus, is one such pony.
It probably doesn't help that there happens to be another pony species that looks just like him.
It probably also doesn't help that the only known members of said species happen to be the rulers of Equestria.

Well...
This is gonna be awkward...
For anyone wondering, I read a story a while back in which a minor side character had a medical condition that caused him to superficially resemble an alicorn and was curious what it would look like if the main character of a story had a similar condition.
This is the result. I hope y'all enjoy it.
