Original Description:
 
I’ve been in this fandom for almost 10 years and I’ve never made a legit OC. So I went and made one. Pretty much since the beginning I’ve been known as Soctavia, the grey mare. As such, I wanted my OC to still fit that description. I wanted her to look similar enough to Octavia without looking like a direct copy, and I wanted to give her a reason to be called Soctavia. With those things in mind, I began throwing something together. I created a very rough sketch of my idea and filled out some generic OC description template I found online. I might be making changes here and there but I’m satisfied with her for now.
 
So yeah, here’s Rocky Karst, also known as Soctavia. A dirty half-breed from a Kirin and Earth Pony! (Not sure if that would call for the Kirin tag or not.)
