Air Mage. Free Cities

A shapeshifting mage named Grei has completed his training at the Academy and has been assigned, by distribution, to Kilder—the city known as the calmest among the free cities. He expects a few years of quiet service, followed by a promotion. But an unexpected disappearance of a skyship and a series of mysterious murders draw him into a whirlpool of events, where the main goal becomes his own survival.
