The Font of Avernus is the source of a family's strength, a crack in primal stones from which vapors of prophetic power have issued for generations. Each newborn of the cavernous House Avernus is bathed in the black mist, and by this baptism they are given an innate connection to the mystic energies of the land. They grow up believing themselves fierce protectors of their lineal traditions, the customs of the realm—but what they really are protecting is the Font itself. And the motives of the mist are unclear.
