I love this! A beautiful page! My favorite thing is the count at the bottom of how many others have the same Achievement. I found that interesting and surprising! Thanks!
For the record, the text for the Confounder of Logic is:
"Some people know the knowns, learning skills that are learnable. Some know the unknowns, learning Unlearning. But one step beyond them all, you have unlearned unlearning, and now unknow the unknown. How Rumsfeldian."
I've never gotten the Rook Ranger achievement text, so I don't know what the text is for that.
