I still thing it is the other way round. Originally.. I said that the sorcerer trapped the author behind the door for his own benefit….that maybe he is forcing the author to write certain things, or sabotage his work (page 2 of this thread and elsewhere a week ago). Perhaps the sorcerer is evil and is punishing the author for not writing a happy ending, or is forcing him to do so, but the author is finding create ways to not give him it.
I’d like to add that the reason why I think the sorcerer has bad intentions or is evil because he possesses a hat that sucks people into it. Yes, that could be a good way to get rid of some truly bad people, but I can’t help but shake off the feeling that any magical person with that kind of hat is not going to be at least a tad shady.
