Khran is a type of alchemy known for being able to tell the future. There are no instances of Khran alchemists in any of the visual novels. However, in chapter 3 while on Nina's boat, there is a fortune teller. Unfortunately, later when Nina's husband attacks the ship, she announces that she is a fraud. As told in the magic history section in the Ildris library, Khran is a forbidden arcane art.
