An incredibly powerful male unicorn. I don't have a back story for him just yet, but He is night based. I was thinking of something like Nightfall Gloom or something like that. His cutie Mark is the mark of the Ouroboros. It was his influence from the shadows that was the true reason that turned Sombra evil and allowed him to ascend to power. King Sombra's shadow form is a weak incomplete clone of his powers. Nothing is known of his goals. Also thinking of maybe Nightfall Malaise
