On a number of threads there's been some speculation about the starting premise of Discovery being related to the "Massacre on Tarsus IV" - I thought I'd try and draw some of it together and see where it goes.
The Tarsus IV incident fits neatly with some of the previously released information about Discovery - i.e. it is "an event in the history of Starfleet that has been talked about (in previous Star Trek shows), but never fully explored" and involved an exotic fungus (which would explain the inclusion of an astromycologist on the new crew). It occurred prior to the supposed beginning of Discovery's timeline; though for some people it happened a bit too far in the past.
Some people have suggested that Discovery focuses on dealing with the fallout of this event, such as other planets (possibly Klingon) experiencing problems with the same fungus.
But what if (and I admit to speculating here without evidence) the origin of the fungus lay with the Klingons - Tarsus IV might have been a test of a new biological weapon? Might this be the preferred weapon of choice of the new "ancient" or "precursor" Klingons?
