Mea transitioned from the Age of Cold to the Age of Light, then to the Age of Turmoil, and now to the Age of the Wheel, marked by the discovery of a mineral that revolutionized the weapons industry—Grimstone, mined from the Gralian lands and forged into weapons for the Exerians.
Each era lasts for thousands of years. A year on Mea has 300 days, divided into 10 months, each consisting of 3 "decimal weeks." The moon completes a cycle every ten days, so each day corresponds to a different phase of the moon, which is why the days are named uniquely. The months are also named after various dimensions of the universe—not only the three worlds within Radrum, but also the lands of the Gods, the Deserts of the Dead, and the astral dimensions. This system yields the following names:
