Klause Schuar the Grand Bastard (Aevalin and the Age of Readventure, #1‪)‬

Klause Schuar, the Grand Bastard who destroyed the world in his pursuit of magical power, believed to be a only legend by some, is a horror of the distance past. Though seven-hundred years after the Age of Darkness, the world is birthing itself anew—the dark magicks have receded and the festering plague that extinguished entire kingdoms is no more. The roads have been opened and regular travel between nations is now possible. The newly formed guilds are active. Where monster hunting and dungeon diving are lucrative trades, long dead kingdoms are being rebuilt in this glorious age of rediscovery.

This is the story of Arlian Brennovo, lord and commander of the City Watch during the last days before the Age of Darkness—before the Age of Readventure!
