Tim is extracted from office life by a trickster god and deposited in the magical world of Iocusinte. His peculiar curse: his class and physical appearance shift randomly while skills progress. To survive, he must master combining abilities from multiple classes, never knowing what power set he'll possess next. Various factions seek to exploit his unique nature. The trilogy follows Tim's learning curve as he develops adaptability and tactical depth in a world where constant change is the only certainty.
