- This thread has run its course. You will find newer threads in the discussion section.
Another discussion thread - the fourth - has reached the (arbitrary?) 500 comments threshold, so it's time for a new thread for Eliezer Yudkowsky's widely-praised Harry Potter fanfic.
Most of the paratext and fan-made resources are listed on Mr. LessWrong's author page. There is also AdeleneDawner's collection of most of the previously-published Author's Notes.
Older threads: one, two, three, four. By tag.
Newer threads are in the Discussion section, starting from Part 6.
Spoiler policy as suggested by Unnamed and approved by Eliezer, me, and at least three other upmodders:
You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).
If there is evidence for X in MOR and/or canon then it's fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that "Eliezer said X is true" unless you use rot13.
It would also be quite sensible and welcome to continue the practice of declaring at the top of your post which chapters you are about to discuss, especially for newly-published ones, so that people who haven't yet seen them can stop reading in time.
I get this as meaning you can’t use the Time-turner inside Azkaban. I’m not sure if this is relevant to the story, but could one “duplicate” himself (or more) outside Azkaban, and then get all copies inside it? E.g., go to Azkaban, get out, go back to before entering Azkaban, and enter again? Are you forbidden to go back in time over a period you were in it, or is your copy prevented from approaching, or what?
A copy with knowledge of a Azkaban at a certain time seems forbidden from approaching/entering Azkaban at a prior time. See "Azkaban's future couldn't interact with its past, so she hadn't been able to arrive before the DMLE had gotten the message," in Ch55. The restraint isn't so much when the DMLE gets the message, it's when Azkaban sends the message. It can't send a message that affects its past.
Azkaban might be a good place to try a can of Comed-tea.
