I doodled a pony! :3
I've named her Tainted Glass. Her special talent is looking into ponies dreams, but due to the magical taint that she came into contact with when she was young, she can only see nightmares. In addition, if the nightmare is strong enough, her magic will resonate with it in such a way that it will create an illusionary realm based off of said nightmare, but such an occurrence is very rare and has only happened once.
I just really liked how King Sombra looked and wanted to see if I could come up with some kind of magical taint thing based off of it. So I came up with this.
