We all know about Moon!Varian, But have you heard about BlackRock!Varian? Basically the Blackrocks are sentient and also need a host just like the moonstone and sundrop, but they basically end up possessing a child instead, The Blackrocks pledge they're loyalty to the Moonstone but due to the new moonstone holder being manipulated by Zhan Tiri they instead want to cause chaos with or without the Moonstone's Permission (Keep in mind that a lot of this will be similar to my other book titled: Two Sides Of One Alchemist)
