Neither of them noticed the tall stone worn as though from a thousand years of age, upon it a line within a circle within a triangle glowing ever so faintly silver, like the light which had shone from Harry's wand, invisible at that distance beneath the still-bright Sun.
This is going to be vitally important in the future. Thoughts on what it could be?
Storehouse of lost knowledge from the Peverells is my guess, perhaps their notes or a Slytherin-esque way around the Interdict.
If not, the notes would be enough for Harry to start brainstorming a way around the Interdict.
Maybe certain other Deathly Hallows symbols will now light up in Harry's presence, especially if there is a lost storehouse of some sort with a similar mark.
If it doesn't end up being important, it could just be whatever enchantment is on the Peverell gravestone that makes it recognize someone's anti-Death resolve (possibly only if they're a Peverell descendant) and recite the prophecy, pointed out in the narration so the reader knows where the prophecy was coming from.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 96. The previous thread is at almost 300 comments.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system.
Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, .
