869 (The Heroic Age on Qo'noS)
With the tyrant overthrown, Qo'noS united, and the people given a
set of laws by which they could conduct themselves honorably,
Kahless The Unforgettable writes down the true account of his life.
He then departs for a place called Sto-Vo-Kor: "Where no one lacks
sustenance or bends his knee to anyone else. Where in every hall,
the clash of swords rings from the rafters. And where men hold honor
above all else." Kahless indicates its location by pointing to a star
in the evening sky before leaving. A monestary will be established
on Boreth in the future, the world orbiting that star. The
so-called Heroic Age of Qo'noS will shortly come to an end. The
achievements of Kahless will be recorded in the Sacred Texts,
though distorted by myth and legend. In 2263, the Excalbians will
re-create Kahless based upon the conceptions of Captain Kirk and
Commander Spock of the "Enterprise." In 2369, a clone of Kahless
will be created. In 2371, the long-lost scroll of Kahless
documenting the man's real life history will be uncovered on Qo'noS
by Olahg, and utilized to spearhead a conspiracy against Gowron
[TNG 249, SC, GN 24].
