First off. He’s not a paint, he’s actually just a normal unicorn. His early design was inspired by jitterbugjive’s character slate, however his character diverged from that fairly quickly.
His markings are actually a type of dark magic corruption. They have no set pattern (aside from the constant presence forming his right ear and covering his right eye), it reacts to his emotions, covering more of his body when he’s affected by strong negative emotions, reducing when he has positive emotions.
The corruption gives him no obvious benefits, and it appears to feed off his negative thoughts, often adding to it by seeding thoughts of doubt in his mind.
Several attempts have been made to remove it, however, each has ended in failure.
However, while he isn’t a paint pony, he is constantly mistaken for one. This has allowed him to get away with many things that would have normally ended up with him spending time in prison.
The years of living with the corruption, plus major events in his past have had a strong impact on his mind. Over time he’s strong narcissistic tendencies, with frequent bouts of paranoia.
His talent is in the magical manipulation of crystals. Originally, this earned him a comfortable, yet modest, income in a small shop he ran in Manehattan, creating crystal figures and glassware for the elite.
His skills are possibly sharper than ever, in spite of the events that have happened to him, and he now uses his talent to craft any items he may need.
His current location is unknown, though it is believed he is somewhere in the crystal empire, searches have yielded no results, and the Manehattan guard have an alert out for his arrest in relation to an explosion that occurred at the location of his shop the night he went missing.
Naturally, clouded crystal is not his actual name. After the trauma and events following his infection, he adopted the new name in an attempt to leave his past behind, and to try to move on. However, the past, never seems to be too far behind…
