With the recovery of the Kintargo Contract and numerous alliances in place the so-called Silver City of Kintargo and its surrounding region of Ravounel is now protected from invasion by Cheliax. The heroes of Kintargo are ready to sign formal treaties and accords with Cheliax to secure Kintargo’s independence yet enemies made during the region’s liberation remain active and bear grudges. Worse the one-time despotic ruler of Kintargo Barzillai Thrune lives on in the depths of Hell and his plans for the region have only been slowed. Strange manifestations of ghostly spirits and infernal hauntings spread through Kintargo and before long the truth cannot be ignored-the high-inquisitor's death has only made him more powerful and the secret to stopping him forever lies hidden in the roots of Hell itself!
