Finding The Special Admin Key
There is a note in the admin logs from Randolph. It says that a new admin key was made, but it does not follow the usual format.

To find out more, you need to go to the bookshop and buy a special floorplan book. It costs 50 gold coins, and you must request it. Look at the last page of the book, it says:
- The suspect is “A. Key” (admin key).
- The suspect is a minor (from the blue memo, so it’s true).
- The suspect is also a major (from the red memo, handwritten, so it’s true).
On the page before, you can see the word “major” written as ma l jor. Now, check the suspect list.
You need to use a magnifying glass to see it. You are looking for someone who is young (minor) and also matches ma l jor. The only person who fits is Bo Lee.

Randolph said the new key did not follow the usual format, so this makes sense. Bo Lee’s admin key is LeeB.
Once you enter the key LeeB back at Blackbridge Grotto, check the logs again. You will find more details and secrets.
