Well, this Bella is an Alicornist - she's introspective and with a problem-solving mentality. In some ways, this fic is a better sell for Alicornism than HP:MOR (which I also like) is for EY's ideas. For one thing, Bella feels like a perfectly plausible 17 year old girl. She's not a prodigy and doesn't have any active magical abilities. It's easy to identify with her and the fic plausibly shows her as the equal of very powerful supernatural beings, just by virtue of adhering to Alicornism.
I feel like the word for someone who practices my general belief system should be "unicorn".
In the vein of the Harry Potter and the Methods of Rationality discussion threads this is the place to discuss anything relating to Alicorn's Twilight fanfic Luminosity. The fanfic is also archived on Alicorn's own website <strike>(warning: white text on black background)</strike>.
Previous discussion is hidden so deeply within the first Methods of Rationality thread that it's difficult to find even if you already know it exists.
Similar to how Eliezer's fanfic popularizes material from his sequences Alicorn is using the insights from her Luminosity sequence.
Spoilers for the fanfic itself as well as the original novels need and should not be hidden, but spoiler protection still applies for any other works of fiction, except for Harry Potter and the Methods of Rationality chapters more than a week old so we can freely discuss similarities and differences.
EDIT: Post-ginormous-spoiler discussion should go to the second thread. (If you have any doubt on whether you have reached the spoiler in question you have not.)
