The young boy who Lucas rejected to teach manic to, is the man controlling Claude's brother. Because if you remember that there were two thoughts sometimes when it came to the brother and when it came to Diana he said he didn't want to kill her, but another thought said to.
*magic*
Spelling
i don’t remember who he rejected （/TДT)/
yes yes exactly wasn't he also called the most powerful emperor in history. Interesting
An old Emperor. Just a man who had little magic power at that time.
I have a feeling that this guy ( Claude brother )is being controlled by someone else and i think Ik who it is and also the reason he still alive is has something to do with black magic. Maybe the soul that is controlling him healed his body so it could use it as a vessal
