There's a lot more crazy hijinks involved. Turns out that Dhistan's father wasn't even dead. He figured out that Dhistan summoned the succubus using Analyse Dweamour, then racked up humongous debts and staged his own death. When Dhistan returned, they told him that he would inherit his father's wealth (and Dhistan knew his father was a powerful wizard, so he agreed), causing him to become hundreds of thousands of gold in debt. Anyway, Dhistan's father Tarinthel eloped with the succubus, whom he had treated with Wisdom-draining poison and then saddled with a helm of opposite alignment. Dhistan eventually got back the elven souls from the Abyss, but Bel opportunistically grabbed a bunch of them, so Dhistan agreed to sacrifice souls to Bel for a 2:1 exchange rate. Then, Dhistan decided to take on a dragon alone to pay his debts and died. Playing as his cohort, he made a plan to bluff the dragon into giving back the black sapphire containing his soul. He pretended that his cohort (an erinyes) was a minion of Bel (which she was, originally; Bel had sent her to spy on him as part of his earlier agreement) who was making a transaction for Dhistan's soul. Unwilling to forge the signature in case the dragon spotted the fake, he got the real Bel to sign the contract. Not the best idea.....maybe I should write a story hour of all this? Anyway, years later the group decided to team up with the cult, since the cult had become too entrenched to defeat at that point, and they needed some help against the Vandolian Empire...
