I finally found out what my pony OC is. She is the only female Time Lord, aside from River Song.
I know a lot of people have given me grief over having a alicorn as my OC, I really don't give a damn what they think.
I am related to royalty, in real life, so I have more "right" Than most people I would say.
Anyways I wanted a good backstory, for her, since just having her would be like meh. So I'm still working on it. But I have an idea for it.
Will update when it's more fleshed out
