Contest of Wills
Fzoul Chembryl, the ambitious Chosen High Priest of Bane, joined the Zhentarim when Lord Manshoon (then leader of the Zhentarim) forged an alliance with him. He served as second-in-command for years, seemingly content with his position, but he schemed with another high-ranking Zhentarim, the Lord Orgauth (the lord of Zhentil Keep who was, in fact, not human as he seemed, but a fell pit fiend) and eventually ousted Manshoon from power. Fzoul intended to turn the Zhentarim into an arm of the faith of Bane, and forced from the Zhentarim both loyalists to Manshoon (including Manshoon’s lieutenant, the powerful mage Sememmon) and the faithful of the rival deity of Cyric. This led to a brewing war within the organization, with the western Zhentarim of Darkhold led by Sememmon and the Cyrisists opposing the Zhents and Banites, until Sememmon was forced to abandon Darkhold and go into hiding. The Zhentarim of Darkhold, however, led by the evil Cyrisist knight known as the Pereghost and a priest of Cyric called Dhamir Ercals, remain at odds and on the verge of war with the Banites. Fzoul, after Orgauth was slain, had almost gained full control over the Zhentarim. An agreement made with Khelben Arunsun prevented Fzoul from organizing Zhentarim expansion into the Sword Coast, but the agreement would not last forever.
