Oh look (deep link to "Lights across the multiverse") some details about Guardian or at least what Dante has seen of it
. I revised the phrasing of that reply shortly ago because I need practice writing longer coherent posts and my first version of it wasn't very coherent. (I don't think I actually changed any substance
but it's hopefully now easier to read.)
In other news: writing Dante is fun! [He is maybe not the best at explanations (and part of that is my fault), but still.]Edit
: Having read that synopsis of "Aristotle and Dante Discover the Secrets of the Universe", I am pretty sure I've never heard of it before. That is a weird coincidence.
