- A new map has been added to the Atlas, contributed to the Lexicon by Hermione. It’s a beautiful map of the chambers under Hogwarts where the Philosopher’s Stone was hidden. I have added links to it so you can click on various places and be taken to relevent places in the Lexicon, but as a result the page is approximately 170k. If you have comments on that, either good or bad, by all means send me an email and express your view. If it seems like most people would rather not deal with pages of that size, I’ll turn it back into just a normal map.
