Lyranthium is formed from the primordial chaos.
Little is known of this Age, save for ancient carvings depicting a world ruled over by wholly alien beings who shaped it from its infancy into an environment that, incidentally, would make it quite inviting for future races to live.

Humanity spreads out from Khaphtela, displacing many of the older races that had settled there previously. The elves fight to maintain control of their sacred sites, using their superior mastery of magic, but they learn how innovative sufficiently motivated humans can be. The human settlers establish the first major empire of Anvestris, known as Arcadia, where they seek to unravel the secrets of the universe. However, the Arcadians' curiosity is almost their downfall...
The Time of Darkness is a period of 250 years at the end of the Age of Conquest, ending with the Year of the New Prophets. Beginning as it does with the rise of a number of Old Ones and the-near destruction of many civilizations, the Time of Darkness is marked by the arrival of a number of terrifying creatures in Lyranthium, and the collective struggle of all the surface races to prevail against them.
The current age; civilization has emerged from the Time of Darkness with the aid of a new generation of gods and sealed away the Elder Things that had threatened the future of humanity.
In the first year of what will come to be called the Age of Enlightenment, a handful of people are contacted by various benevolent deities to lead their respective peoples out of the Time of Darkness and into a new age of light and wisdom.
