that with the defeat of the XIVth Legion and Gaius's death, effectively ending the Garlean invasion of Eorzea, the leaders of the three citystates officially declare the 7th Umbral Era over, and the beginning of the 7th Astral Era - naturally some may consider that a little premature, what with the Ascians still plotting trouble and the beastmen continuing to summon, but the immediate threat to Eorzea, the Garleans, were eliminated effectively, so thus declaring the 7th Astral Era would at least serve a much needed morale boost for the public at large if nothing else.
But I digress.
