The ghosts are memesis versions of the Justina council that once existed, they always haunt trinity but they're supposed to protect trinity by enforcing contracts or something. They were meant to protect the Eden treaty originally.
Arius took advantage of them by using the royal blood to sign an entirely different contract against Trinity, so the ghosts would attack their own school. All the Eden treaty required was a signature by two different parties I think, they used legal loopholes to control the ghosts

A memesis is kind of like a clone but also somehow different, maybe it's like a record of something that once existed. A memesis is considered a type of Terror, a lot of supernatural things might be considered either mystics or terrors.

Won't be that long before newfags get far enough Into the story that we have to start explaining the mystic, the terror, the sublime.
