This is a thread for discussing my luminous!Twilight fic, Luminosity (inferior mirror here), its sequel Radiance (inferior mirror), and related topics.
PDFs, to be updated as the fic updates, are available of Luminosity (other version) and Radiance. (PDFs courtesy of anyareine). Zack M Davis has created a mobi file of Radiance.
Initial discussion of the fic under a Harry Potter and the Methods of Rationality thread is here. The first dedicated threads: Part 1, Part 2. See also the luminosity sequence which contains some of the concepts that the Luminosity fic is intended to illustrate. (Disclaimer: in the fic, the needs of the story take precedence over the needs for didactic value where the two are in tension.)
Spoilers are OK to post without ROT-13 for canon, all of Book 1, and Radiance up to the current chapter. Note which chapter (let's all use the numbering on my own webspace, rather than fanfiction.net, for consistency) you're about to spoil in your comment if it's big. People who know extra stuff (my betas and people who have requested specific spoilers) should keep mum about unpublished information they have. If you wish to join the ranks of the betas or the spoiled, contact me individually.

Now, the fact that her magic now has an avatar might change the rules, but as Alicorn obviously didn't intend for it to work like how you are describing, you can assume that her magic is still limited to needing to be in communication with the person in question for it to determine whether the analogies fit.
Even with those constraints, there are experiments that seem worth performing.
Experiment one: select some known object X. A confederate either puts X in their pocket, or doesn't. Elspeth attempts to say "You have X in your pocket" to the confederate. Does Magic object to Elspeth saying that when it isn't true?
If that doesn't work, set up an indirect version of the same thing where, instead of saying "You have X in your pocket," Elspeth calls up a memory of the person having X in their pocket and says "You're in a situation like tha... (read more)
