I'm more interested in Wanda's denial of retconjuration's existence. Is it the magical boogeyman art of Erfworld that people honestly don't believe in, or is just a 'we don't talk about it in polite company' thing?
Its like a theoretical element, possible for it to exist, but impossible to create, according to the Magic theory aristoleanesque grid thing - held to be something only the titans can do.
Since it replaced deletionism, rather late in the story, after the main plot has been sketched out, highly unlikely to play a key role.
