Niv-Mizzet keeps information compartmentalized among the members of his guild. In his head, he keeps various experiments, research projects, and elemental explorations organized so he is the only one who perceives the way all of them intersect. As he receives the results from one line of experimentation, however chaotic its methods, he then orders a new line of experimentation on a seemingly unrelated topic. Niv-Mizzet demands to know the outcome of every concoction and elemental inquiry; even what might appears to be a failed experiment might later prove to be a key ingredient to Niv-Mizzet's larger plans.
Most believe him to be a batty, information-obsessed old dragon, but secretly, Niv-Mizzet is conducting a scattered, grand meta-project he calls the Interlocus. The purpose of the Interlocus—and indeed, its existence at all—is difficult to detect, as the sheer range and number of experiments that feed into it would fail to suggest any kind of pattern to most observers. But to the Firemind, all these lines of research help him get closer to answering the metaphysical riddles that perplex him.
