Inheritors of Chaos — Barbara Ann Wright

Naos has come to Calamity, and chaos has come with her. Cordelia had enough problems without teaming up with former enemies in order to defeat a mad goddess. And she doesn't yet know that the Storm Lord has been resurrected in a new body. On the plains, the prophet Lydia is convinced that Fajir is the one chosen to stop a massive firestorm in the future, if only Fajir wasn't so set on killing everyone around her.

With their murderous leader dead, hostilities have ceased among the drushka, but the long-living aliens are slow to adapt. The last thing they want is a drushkan king with powers none of them dreamed of before.
