It is my belief that everything that happened at a specific time (everything with "incident" or "affair" in the title, for example) should be marked on the timeline. I've just spent an hour cross referencing everything I thought should be there and updating the timeline accordingly. I think I got it all right, and there should be no discrepancies. Given my mortal status, however, it's always possible that I've missed something. Plesae take a moment and review the page, and if you find that any alterations are necessary I'd like to know.
Also, if someone believes that not everything should be on the timeline, this is probably the time to say so.
