Star TrekFans Got to See the Klingon Culture Evolve Over Time

TheBat’lethIs Central to Klingon Culture

From the very beginnings of theStar Trekfranchise, the Klingons have been central to it. The introduction of the Klingons in the first season of the Original Series made theStar Trekuniverse a darker, more dangerous place. Originally portrayed as bloodthirsty, savage and cruel, the Klingons waged at least one bloody war with the Federation, as seen in the first season ofStar Trek: Discovery. The two powers began the process of burying the hatchet after the explosion on Praxis, but the process was a slow one, and tensions persist decades later.

Kahless is still highly regarded among Klingons, and even his clone was afforded a high status in the Empire.

Beyond its distinctive design, thebat’lethoccupies a vaunted position in Klingon culture. According to legend, Kahless forged the firstbat’lethin the fires of a volcano, and then used it to slay the tyrant Molor. This led to the unification of the Klingons, who had previously warred among themselves. Also, central to the Klingons is the concept of honor, and Kahless introduced this to them as well.

Thebat’lethwas designed byStar Trek: The Next Generation’sVisual Effects Supervisor Dan Curry.

Unfortunately, Kahless II went astray, leading an uprising against the universe’s gods,as chronicled inStar Trek: Day of Blood.This brought him dishonor, but Sisko is offering him a way out by anointing Kahless the new Emissary, and the vision he has inStar Trek#30 is a means of purifying himself before taking on Lore. Kahless’ forging of the firstbat’lethwas a key moment in the development of Klingon society, and the saga of its creation plays out again in his vision. The key difference is that this newbat’lethwill be instrumental in defeating Lore.

Will theBat’lethRedeem Kahless?

And just as thebat’lethis instrumental to Klingon society as a whole, it will now become crucial to restoring theStar Trekmultiverse. The Sisko gave it cosmic purpose, imbuing it with a sliver of his own power, enough to awaken him in the new and corrupt reality Lore has created. It must also be powerful enough to kill Lore—no small feat as he has established himself as a god as well. So much is now riding upon Kahless and his cosmicbat’leth, making it the most important weapon in theStar Trekuniverse.
