The Eazor are rumoured to be a people not from Avwo. The legend tells of giant armies that crossed from another world into the world of Avwo.
There is evidence of artifacts being enchanted by Eazor magic, also there was no magic before their arrival. A lot of this has been speculated to be true, but the people aliva back then didn't understand what was going on. The Droteron Empire was the only Empire, technologicaly advanced enough to understand a little.
