Did someone call for a badass mage to stop petty nobles from squabbling and face the real threat-unbridled Chaos?

In a world where the noble elite are supposed to fend off the threat of terrifying Chaos but instead engage in pointless, petty squabbles, young mage Siluca Meletes dreams of bringing justice to the land.

Disaster strikes Siluca and Theo's plans. Their domain is devastated, their holdings scattered amongst other Lords, their allies forced to ally with the victors, and Theo stripped of his title and exiled. How can they rebuild after a near-total collapse?
