The Battle of Gerlach begins at last. How does Rozemyne’s fight against Grausam play out, and what happens to Ehrenfest in the aftermath? Behold the full extent of the explosive war shaking Yurgenschmidt to its very foundation!
I guess it is like how Rosemyne and Ferdinand have the same mana, since Ferdinand dyed Myne. Devouring soldiers can also be dyed if they partially turn into a feystone like Myne did. I guess you then modify their appearance somehow.
Rozemyne considered she might have ended up as a body double for Bindewald or Grausam, so it's quite clear that magic exists, that allows someone to mold the physical appearance of another person to their liking (which might also explain why, with the exception of Bindewald and Fraularm, every single other noble is very handsome).
Between Rozemyne saying that it is possible, if someone was willing to invest the necessary resources and cruel enough, and Rozemyne's physical pain while Erwärmen and Anwachs grew her body, it's very likely quite costly for the performer and painful for the subject. I guess that means that Bindewald was probably either too greedy to invest the resources or too sequeamish to endure the pain of the procedure to make himself pretty.
I think she would've been Georgine's body double. She has the same hair color as her. With a veil no one would notice the difference especially if she didnt speak.
If Bonifatius' instinct was right, which it usually is, Grausam got in and out of the sealed hall through a secret passage, that just so happened to terminate near where Rozemyne was attacked.
Allowing one of his body doubles to be interrogated by Sylvester, Ferdinand and Bonifatius, would have been a massive risk.
