The Vulcan Reformation and the Kir'Shara

By the mid-22nd century the Vulcan High Command, led by Administrator V'Las, had drifted far from Surak's teachings: it spied on its neighbours, pursued an aggressive policy toward the Andorians and persecuted the Syrrannites, a movement seeking to return to the philosopher's original words. In 2154 a bombing destroyed the United Earth embassy on Vulcan, killing Admiral Forrest among others, and the Syrrannites were blamed.

Archer and T'Pol went into the Forge desert to find the truth. There Archer received Surak's katra, his preserved consciousness, and was led to the Kir'Shara, an artefact holding Surak's authentic writings. Meanwhile V'Las prepared a surprise attack on Andoria, which Enterprise and Soval helped to thwart.

Once the Kir'Shara was revealed, V'Las was exposed as a secret agent of the Romulans. The High Command was dissolved, Vulcan turned away from its intrusive role toward Earth, and a renewed interpretation of logic took hold. This change in Vulcan policy made possible the cooperation that would later lead to the Federation.
