Zomaj Hauc was arguably the most demented magelord of the Izzet in recent history. His brilliance and obsession with himself were rivaled perhaps only by his guildmaster, Niv-Mizzet. Within the last few years, he hatched a scheme that, if it worked, would have devastated an enormous amount of the cities of Ravnica. Hiding his plans within the reclamation zone of the Utvara Valley, he worked diligently; exploiting his servants every way he could so that he could bring what he thought would bring the City to his knees, even Niv-Mizzet. His plan involved three dragon eggs he had uncovered years before. Ravnican dragons, in truly ancient times, were immense and god-like, warring and devastating to nearly as great an extent as the Elders of Dominaria. In modern times, the only dragons are a few feeble remnants in the form of drakes, and of course the leader of the League. Hauc heated the eggs up for years, hoping to hatch them and then take over their minds, gaining control of demigods, thus enabling him to smite the Firemind and raze the City, letting him rule from the ashes. Were it not for Agrus Kos, an Orzhov friend of his named Pivlic, and several other primary characters of Guildpact, he may very well have done so.
He finally died by being crushed below the blue dragon that he controlled, when it was killed by another controlled by Teysa Karlov.
