I've been maintaining an offline official timeline of canon for On Overcoming the Fear of Spiders and all the in-universe stories written seperately and collected in intersections in the web of time, and now that I'm making some headway on Old Soldiers, I thought I'd format and post the thing.
It's pretty big. It includes a fair number of things that happened in Fear of Spiders that did not make it into the manuscript or any following story, and also contains a couple of first-chapter background-info spoilers for the new story. So if you're allergic to that sort of thing, don't read it. If you're not, you might find some new background you might enjoy.
