Guide to the Green Sun Princes
Gifted by the Yozis with the corrupted Lawgiver Exaltations, the Infernals represent a new and terrible threat to the world and its Exalted defenders. Offered unimaginable power by the fallen architects of Creation to right their greatest failure, the Chosen of the Yozis operate with one shared goal, to transform Creation into Hell. Will the Infernal Exalted succeed at their diabolic mission, or the Green Sun Princes fall before the Chosen of the gods as their masters once did?
