Since the world Banica goes to is described as "another take on the Third Period", I wanted to create a thread talking about the possibilities of the characters of TTDS world being counterparts to EC characters, assuming that's another "take" too.
Gibbet/Storasphia could probably be Michaela given how Storasphia could turn into a bird (in this case, an owl) and then reincarnated into a human (Rabiah tells Gibbet that Storasphia became Christabel Blanken in Ring of Evil).
Bnack/Vunack would be either Vlad or Banica. We don't know their gender but a wraith that can corrode anything sounds like a great fit for both.
Amostia, even though he was born in the EC world, he could probably be Allen's counterpart given how he's loyal to Rack.
