The Age of Ashes Adventure Path continues! The heroes have claimed the citadel atop Hellknight Hill as their own, but a ring of magical portals in the castle basement could allow cultists from the southern jungles to invade a gain at any moment. The PCs must travel through the first of these portals to ally with new friends and face off against the dragon - worshipping Cult of Cinders before the villains can bring powerful forces of destruction to bear!
