Nivix, Aerie of the Firemind, is the home of Niv-Mizzet and the central guildhall of the Izzet. Nivix is a massive tower, comparable in size to New Prahv. Every level of the tower houses Izzet alchemists, mages, and sages who are constantly theorizing, experimenting, and tossing miscalculated experiments across rooms. The very top of the tower is of course the aerie of Niv-Mizzet himself. Though none of the experimentations of the tower’s residences seem connected, the great dragon treats them all as if they were part of one grand experiment.
