Let me know of any mistakes, particularly with some of the details around the 400 years ago mark, which are a bit murky and muddled.

Question 74 [HIS][Open]
Instead of asking individually for each undated event on the timeline, this is an open question asking for dates for any events. For any of the explicitly mentioned, undated events in the timeline above, give a date and some short details.

Furthermore, for any other implied events that haven't been specifically addressed, such as the invention of hyperspace travel or the exploration of this sector, you can also give a date and some basic details. However, if you want more detail about the event, ask that as a separate question.
