In 2370, during his self-proclaimed "crowning achievement," moments before igniting Epsilon 119 via shuttlepod-suicide, Seyetik quoted "The Fall of Kang", stating "You're looking at one warrior who refuses to be pitied." (DS9: "Second Sight")
It was the original intention of this poem to refer to the legendary Dahar MasterKang, from TOS: "Day of the Dove". However, unknown to the writers of "Second Sight," plans were in the works to bring Kang back for the episode "Blood Oath", which established a contradiction. It becomes conceivable, however, that the modern Kang was named after the epic figure - this interpretation is indirectly supported in ENT: "Judgment", as the "Koloth" cited during Archer's trial is obviously not the one who appeared alongside Kang in "Blood Oath".
While Kang was spared the fate told in the poem, DS9: "Once More Unto the Breach" showed his friend Kor seemingly doomed to this fate, before making the most of one final opportunity and going to a glorious death.
