The School of Light and Darkness was the oldest, grandest, and most important of the seven major institutions of Sanctaphrax,devoted to the study of lumonisity. The Professors of Light and Darkness were in charge of this school.
A magnificent, palatial institution, the School of Light and Darkness was specially designed so that parts of it were bathed in light and parts of it were shrouded in darkness. Its academics wore robes in varying shades of gray, to denote the specific grade of luminosity they studied. The most secretive of all of the seven major schools of Sanctaphrax, the School of Light and Darkness did not engage in the same intrigue, gossip, and faction-fighting that was omnipresent throughout the rest of the great floating city, instead turning such practices upon each other and resulting in internal power-struggles within the school. Aside from the academics of the School of Light and Darkness, only the invited were allowed to so much as enter the building.
