Observations of infrared emission from AGN show that grains exist over a broad range of distances from the central object, extending to the point where they are destroyed by sublimation. These ~1000 K grains produce much of the 1 micron continuum. In this region closest to the central object there must be a gaseous component associated with the hot grains. This paper employs a state of the art grain model and shows that the gas must be very hot, with temperatures in the neighborhood of 10^6 K. The dusty component has a covering factor of roughly 50% and so this region also reprocesses much of the total x-ray emission. Our explicit models of the IR through x-ray spectral energy distributions allow the x-ray component to be predicted from IR observations. We are creating a grid of such predictions and will make them available as an XSPEC add-in, allowing this spectral component to be included in quantitative modeling of AGN spectra.
