Rise of the ancient races
On the only known Continent, Erasia; the mages, has finaly started to be able to use magic again. However the puclic still lokks at spell casters, with fear or anger. As they in the past five years after The Blastwave, had mostly captured and killed people to be able to use their art. Another factor that makes it few spell casters alive is the blastwave itselfe, it killed most of all spell casters. And the last factor is the aging; that is making spell casters age when they use spells.
In addition the last known dragon died over an millennia ago.
