While it arguably contradicts canon, I like to think it's Bella's luminosity in Luminosity that caused the weird vampire talent. Her mind is just special.
Canon has her with the same talent (although luminous!Bella will develop hers along a different trajectory now that she's been vamped). It's not because she's luminous. It's just a magic thingamabob.
Right, that's the aspect that I thought contradicted canon. I can just pretend that canon doesn't exist, and the real reason in Luminosity isn't a magic thingamabob.
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.)
