I started doing timelines for my game books a decade ago. Before that I was doing timelines for games and stories but not in an especially thorough or methodical way, more just keeping key dates straight.
Like I think a lot of writers of my generation part of the influence was the second world historicity of Tolkien and his many imitators. It’s a wonderful feeling to see your world “take life” as dates and places get recorded “as though it were real”.
In the matter of Doctor Holmes, although it began as a brain fart it’s turned into an Earth-Q level pastiche with hundreds of characters and thousands of details. I can never seem to help putting parody into pastiche, I guess I’m just that flavor of hack. 🙂
As soon as I find a good wordpressly way to post the timeline I will do so. I am sore tempted to make a wiki, for my own use more than anything, except I find when doing a wiki that it becomes irritating to have to go back and hyperlink that which originally was not hyperlinked… 🙂
The current Doctor Holmes timeline runs from 1770 to 2046, with a preponderance of Sherlock Holmes era entries and another clumping occurring from the late 1960s to late 1970s. The latter grouping was absolutely not deliberate, just one of those organic occurrences that let a writer know that their story has drawn its first breath and is alive- it is beginning to tell YOU its tale instead of needing you to constantly massage life into it.
Will I ever get to tell every single story mapped out? It seems astonishingly unlikely. Perhaps I will. But the timeline is the key to a cosmos of adventures and I think this pastiche in particular is mainstream enough for other writers and artists to participate -and more importantly want to participate.
