The nextStar Trekshow,Star Trek: Starfleet Academy, can rediscover a lost Klingon relic fromStar Trek: Deep Space Nine. InStar Trek: Deep Space Nineseason 4, episode 8, “The Sword of Kahless”, Lt. Commander Worf (Michael Dorn), Lt. Commander Jadzia Dax (Terry Farrell), and Klingon warrior Kor (John Colicos) venture to the Gamma Quadrant seeking the legendary sword of Kahless, which was lost for 1000 years.Bringing Kahless' original bat’leth back to the Klingon homeworld would repair the Federation and Klingon Empire alliancethat Chancellor Gowron (Robert O’Reilly) recently severed, restore Worf’s lost honor, and earn Kor a statue.
According to prophecy, the Sword of Kahless will unify the Klingon Empire, which is no small feat sinceStar Trek’s Klingon Empire has long been fragmented. The noble Klingon houses of the 23rd century inStar Trek: Discoveryseason 1 are sharply divided.Star Trek: The Next Generation’s Klingonsare still jockeying for power a century later. The Khitomer Accords broker a tenuous peace with the Federation, but Gowron’s controversial decision to break the Accords inStar Trek: Deep Space Nineseason 4 only worsens the Klingon Empire’s internal political turmoil. The Sword of Kahless could fix that, but Worf and Kor let it go for another 1000 years.

Star Trek’s 10 Greatest Klingons
Star Trek has many great Klingon characters from Kor to Worf and Kruge to Torres. But who are the best Klingon warriors that Qo’noS has to offer?
Star Trek: Starfleet Academy Cadets Can Find The Sword Of Kahless
The Klingon Empire Could Reunite In Star Trek’s 32nd Century
After being beamed into space inStar Trek: Deep Space Nine, the Sword of Kahless can be rediscovered in the upcomingStar Trek: Starfleet Academy. Kor and Worf hint that it might take another thousand years for worthy Klingons to come across the Sword of Kahless again, and that just so happens to be in the neighborhood ofwhenStar Trek: Starfleet Academytakes place, give or take a few hundred years.Star Trek: Discoveryavoided depicting any Klingons at all after the USS Discovery’s leap forward in time, soStar Trek: Starfleet Academycan do anything at all with the Klingons ofStar Trek’s far future.
Finding the Sword of Kahless would explain what happened to theKlingons inStar Trek’s 32nd century. One such scenario might play out like this: Starfleet Academy cadets find a mysterious weapon in the Gamma Quadrant. Research reveals it’s a long-lost artifact from the ancient and possibly extinct Klingon Empire. The cadets' quest would be a reversal ofDS9’s “The Sword of Kahless”, with the sword seeking the Klingons, instead of the Klingons seeking the sword. Asthe discovery of Kahless' bat’leth calls displaced Klingons out of hiding, one youth ventures forward to tell the story of the scattered Empire, and becomes the second Klingon in Starfleet.

Why Worf And Kor Let The Sword Of Kahless Go In DS9
The Klingon Empire Isn’t Ready Yet, But It Might Be In The Future
InStar Trek: Deep Space Nine, Worf and Kor agree to let go of the Sword of Kahless, recognizing the corrupting effect that the Sword had on both of them. The Sword of Kahless isn’t explicitly enchanted, butKahless' bat’leth draws out and amplifies toxic ambition in any Klingon who touches it. Worf is keen on reuniting the Klingon Empire by returning the Sword to the Emperor, a clone of the original Kahless, whereas Kor has his eyes set on becoming the new emperor, himself. Worf and Kor would gladly kill each other over different ideas, and they almost do, until an entirely fed-up Jadzia Dax puts a stop to it.
Bringing the Sword of Kahless back to Qo’noS will only exacerbate an already tense political climate.

Kor and Worf reflect the state of the Klingon Empire early inStar Trek: Deep Space Nineseason 4. Bringing the Sword of Kahless back to theKlingon homeworld of Qo’noSwill only exacerbate an already tense political climate by creating deeper divides over who should rightfully wield it.The Klingon Empire of the 32nd century is almost certainly different,but whether the Empire is reduced, fractured, already united, or even still exists is unknown.Star Trek: Starfleet Academytakes place centuries afterStar Trek: Deep Space Nine, so there’s another chance for the Sword of Kahless to honor the Klingon people.
