More than two thousand years ago, the predecessor of the Valeria Empire, the Loren Empire, had not yet collapsed under internal and external strife.
At that time, people determined the solar cycle based on mystical knowledge and established a calendar accordingly, dividing the year into twelve months, totaling 365 days.
Later, as the Loren Empire gradually declined amidst warfare, it split into the Valeria Empire and the Kingdom of Velys along the line from the Abyssal Rift in the northwest to the Barren Wasteland.
This calendar was preserved by both sides and has been in use ever since.
Today is December 30th of the year 1729 in the new era, and there are less than 48 hours left until the new year.
