Theory on Crowley
Alright, this is my first time posting on here, so please I apologise if I make any mistakes. English is also my second language, so apologies for any grammatical errors.
This theory is from this weird dream I had, so don't take it too seriously.
So, I have this theory that Crowley, for one, is Raverne. It would fit with his character, how Raverne was described and it would fit into the story I think. But what I wanted to talk about was, that Crowley might be after the stones that appear after overblots because he himself wants to overblot. I can't remember if it was confirmed what the stones are, but I think they might be mage stones filled with blot. And Crowley has I think four or five magestones on his person (on the keys, his back and his hat I think). So if he is Raverne like I think, it might be his goal to try and overblot to release his own magic similar to how Idia made himself overblot. He might want to bring back Maleanor but can't because his magic isn't strong enough.
The reason he brought Yuu into twisted wonderland might be because he doesn't actually want the students to die but needs them to overblot to get the stones so he can use them himself.
Like I said, this is based off a dream I had so please don't take it too seriously. 😅
