We should state the facts first:
http://m.ign.com/articles/2016/08/1...-years-before-kirk-took-command-of-enterprise
- the show will be
set approximately 10 years before Captain Kirk took command of the USS Enterprise, meaning Star Trek: Discovery will exist more or less in the same time period as the original show.
- Discovery will delve into a part of Starfleet history that has been
spoken of but never shown up until now (and that Fuller is fascinated by). He said it was his chance to "Dig deep into something that for me was always very tantalizing."
- Fuller shot down the following theories, saying
the show is not set around Axanar, Kobayashi Maru, or Section 31. But he did note the Federation event he's referring to is referenced in the original series.
- Sources tell
THR the rest of the cast also will feature an openly gay actor to play one one of the male leads (which Fuller confirmed), a female admiral, a male Klingon captain, a male admiral, a male adviser and a British male doctor.

OK, those are the facts we have to work with. Of course, there are facts and there are
facts. In my experience with every Trek series, it seems the show runners are not as up to speed on the minutia as we rabid fans are. Sometimes show runners lie or stretch the truth or tell the truth "from a certain point of view" in order to keep the suspense and secrecy, while teasing us a little. Sometimes show runners are willing to alter or ignore certain facts for the sake of artistic license or creativity.
Hollywood reporter's comment about the Klingon Captain being part of the cast is interesting. Since we're talking Pike era, that means Klingons are the enemy. We're not talking about Worf or TNG era Klingons. If this is true then we'll be seeing a lot of the Klingon side of the story. Sounds like one of the main or recurring villains or plot foils is part of the main cast.
With that thought in mind... I have some musings about how ambiguous those facts are. Is the series set 10 years before Kirk took command of the Enterprise or 10 years before Kirk was born? I've seen fans speculate both, even after reading the release. Either they didn't read or they misremembered. Let's go with 10 years before Kirk took command. Now, I still don't think that's a hard 10 years. Maybe it's 9 or 11 years. To cover all our bases, we should look 5 to 15 years before Kirk took command.
I wen through Memory Alpha twice looking from 2245-2265. Here is what I found that might work.
2245 The
Battle of Donatu V is fought between
Federation and
Klingon forces near
Sherman's Planet. The battle ends without results. (
TOS: "
The Trouble with Tribbles")
2246 An exotic
fungus destroys most of
planet Tarsus IV's
food supply. (
TOS: "
The Conscience of the King"),
James T. Kirk - at the age of 13 - is one of nine surviving eyewitnesses to a massacre of some 4,000 colonists of
Tarsus IV by
Governor Kodos. (
TOS: "
The Conscience of the King")
2250
Robert April leaves the
USS Enterprise as its
commander for an appointment as
Federation ambassador-at-large. (
TAS: "
The Counter-Clock Incident")
2255 The
Treaty of Armens is established between the
Sheliak Corporate and the
United Federation of Planets. The
treaty cedes several
Class H planets from the Federation to the Sheliak. The treaty contains 500,000 words and took 372 Federation
legal experts to draft. Upon concluding the treaty, the Sheliak ended communication with the Federation. Talks between the two would not happen again until the year
2366 when a dispute arose over a
Humancolony on
Tau Cygna V. (
TNG: "
The Ensigns of Command"), Lieutenant James T. Kirk, on his first
planetary survey mission, visits the
planet Neural, where he meets
Tyree. (
TOS: "
A Private Little War")
That's all I could find that would be noteworthy enough to involve the
USS Discovery. Now, out of those events, I see 2 that involve or could involve the Klingons. 2245 The Battle of Donatu V and 2255 Kirk's visit to Tyree's planet. I'm suggesting the visit to Tyree's planet only because the Klingons were involved in "A Private Little War." The incident itself is not noteworthy.
So, maybe we're talking about the Battle of Donatu V? This would involve Klingons. A Klingon captain is supposedly part of the main cast. A battle would suggest ongoing or prolonged hostility. This era is the height of the Federation/Klingon cold war.
The 2255 Treaty of Armens is interesting. I've seen others mention the Sheliak. Such a treaty might be of interest to the Klingons. However, is Fuller's tease about the event being mentioned but not seen on screen specific to TOS or can it include TNG?
I've not found anything else. I'm open to ideas or suggestions.
