Terra Firma (TSoA)
The Scroll of Askafroa began in the country of Perchta, and was completely set in that land at the start. The initial plot is set when an old scholar friend, Zeloth, contacted the first four party members about an important opportunity they couldn't afford to miss. The modern calendar of Terra Firma was set after the Great Calamity - the summoning of a Tarrasque that destroyed most of Northwestern Perchta, and left the country a relic of its past self. One century after the Calamity, Zeloth discovers an error in translation from the primordial tongue of the Cultist that summoned the Tarrasque - there were two scrolls created, not one, and it's still somewhere in Perchta. From there, the story went on quite a wild ride, and soon, a grander world had developed, bringing with it quite the change in objective for the party of now six.
