The last known catastrophe, a vast series of earthquakes, in 2847 marked the end of the Age of Embers. Since then, civilization has slowly been rebuilding. Though the occasionally tome of ancient knowledge or ruins are discovered, civilization is starting mostly afresh.
During the Age of Blaze, temples were built to each of the faiths and served as a place of pilgrimage and worship for all followers. After the End times these temples were abandoned and lost and it is not until the Age of Rekindling that these temples are being rediscovered, one by one.
We currently live in the Age of Rekindling in 6002AET.
