Chapter Thirty-Eight: Illusion
If this Conjurer fell in the department that experienced reaction, similar to sexual excitement or exhilaration, when dueling someone stronger or has potential to be stronger, then it'd be safe for Alexandria for the meantime as long as she thinks he has potential to beat her.

"Haven't found it yet?" Zenith leaned on the wall.
Escanor noticed he rested on the moss-filled walls, he must've grown impatient, but he'd have to wait longer.
To access a spirit realm, Escanor had to use one of his dead to find it. The Conjurer controlled spirits, while he could control the dead and command them to do what he wants by infusing essence in them.
