The Great Elf-Orc-Wars marked the end of the First Era and the beginning of the Second Era.

The survivors of the Elf-Ocr-Wars start to pick up the pieces. Most of the reconstruction work is done by the secret societies that had led the revolts, many being dominated by small groups of magi.
Most of the books and other forms of written records are lost, thus much information from older times is legend.

Period of Beaver: The founding of the six empires on the continent of Myaasia.

The Accords of Empires: the six empires agree on borders and peace between themselves. Powerfull magic items are Created by Iorak to ward the empires and the treaties.
About this time Iorak and Ulane were seen as Major gods.

Periods of relative calm with the six empires coexisting peacefully.

Period of Bear: Rise of the dragonlords. The 12 dragonlords gain power among the dragons withing a span of a few years. Their origin is unclear.
The Dragonlords made their presence felt in global politics, destabilising the global political situation.

First mentions of Greyre.

Period of Wolf: First mentions of Jaysek And Kieron.

Period of Destruction: Mage Wars
A total global war with spells capable of wrecking whole cities.
Allmost all cities on Myaasia are destroyed.
Seven of the dragonlords die and all the great magic societies are shattered, as are the great dragon armies. The total deathtoll is impossible to count, but scholars claim that about three quarters of the global population perished. Even several Greater Gods seem to vanish.

After the Mage Wars ended, the counting of periods started again with the Third era.
