might not work well, but by navigating to a very harry potter dominant part of latent space by preconditioning on the books you make it more likely to get good results. An example would be taking a base model and prompting "what follows is the book 'X'" it may or may not regurgitate the book correctly. Give it a chunk of the first chapter and let it regurgitate from there and you tend to get fairly faithful recovery, especially for things on gutenberg.

So it might be there, by predcondiditioning latent space to the area of harry potter world, you make it so much more probable that the full spell list is regurgitated from online resources that were also read, while asking naive might get it sometimes, and sometimes not.

the books act like a hypnotic trigger, and may not represent a generalized skill. Hence why replacing with random words would help clarify. if you still get the origional spells, regurgitation confirmed, if it finds the spells, it could be doing what we think. An even better test would be to replace all spell references AND jumble chapters around. This way it cant even "know" where to "look" for the spell names from training.
