Era beginning/end
The time of the unified spell weaving that cast the Kolonati off of Erathia.
The Gods chose to intervene in the strife of the world. They crafted a powerful magic that would cast out the Kolonati and seal the world away from them. This would however have the side effect of sealing the Gods away as well. To accomplish this, they had the Silvari teach magic to as many as they could, and together with the free peoples of Erathia weaved the spell that would change the world forever. Some gods chose to stay in the mortal realm, sacrificing their immortality and much of their power in doing so. And so ended the Age of Gods, and began the Age of Rebirth.
