4th Century
On Vulcan, the Time of Awakening occurs, referenced to as ‘the Sundering’ by later Romulans: Being eventually driven off the planet, ‘Those who march beneath the Raptor’s wings’ fight a terrible civil war against those Vulcans who follow Surak’s teachings by embracing logic. [STO]
Surak’s followers eventually defeat the other Vulcans and cast them out. Using huge generational ships and having taken along revered artifacts e.g., the Sword of the Raptor Star, the outcasts temporarily settle on Dewa III before moving on and finally reaching Romulus. [STO]

Kahless the Unforgettable defeats Molor and the Fek’Ihri, uniting the Klingon people for the first time. At the end of his life, Kahless points to Boreth and tells his followers to look for him there. [STO]

The Hur’q, an insectoid species from the Gamma Quadrant, sack Qo’noS, stealing the Sword of Kahless in the process. [STO]

On Ferasa, a eugenics program aimed at creating Augments and involving Ferasan Nepeta Leaves as psychotropic triggers leads to a split of the indigenous civilization.
