Niv-Mizzet is the draconic leader and parun of the Izzet League and is at least 15,000 years old. His intellect exceeds that of standard mortals by several echelons, and he is known for many ingenious inventions that currently serve the citizens of Ravnica, the most well known being the almost indestructible, yet easily usable and forgeable metal, Mizzium. He has not been seen publicly for over 2500 years. He is the source of the Firemind, an extrasensory link to Niv-Mizzet’s omniscience. To possess it is to be immersed in passionate brilliance. Not all Izzet are in tune with the Firemind though; the honor must be earned by passing a test or by accomplishing an extraordinary achievement.
