In canon, the map was made by "Moony, Wormtail, Padfoot and Prongs". I'm pretty sure Voldemort could override an artifact made my four teenagers.
It was labeled as made by them, which isn’t necessarily reliable information, considering the incantation you use to activate it. And at one point it’s shown to locate and identify people under the True Cloak of Invisibility, which seems like powerful magic. (It could also be “made” in the sense that they found some sort of magical ingredient or component, ancient and much more powerful than they could make, which the integrated into the map, or even just that they customized an existing map with their silly “access code”.)
And in MoR, Dumbledore himself needed to use the map. Which suggests it was much more powerful than what four of his students could have made.
The next discussion thread is here.
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 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
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.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
