Fiery Furnace

It is 1234, and heretic Olivier de Mazan possesses a secret that makes him a prime target of the Inquisition's secular thugs. At the same time, Count Raimond of Toulouse and Queen Blanche of France are using the boudoir to pursue the policies of their respective dynasties.
Olivier's grandsons - Odon and Rainier - come of age fighting the French usurpers at the side of Robin Hood's son, a veteran mercenary. Along the way, the lovely performer Huguetta steals Odon's heart, and Rainier loses his own to Miranda, who embodies Olivier's secret.
In contrast, Count Raimond risks a rupture with Blanche by attempting to save his dynasty via strategic marriages and consequently delays rescuing his subjects trapped in the mountain fastness of Montségur, "Mount Secure."
In this continuing saga, a Cathar family embarks on an epic struggle as they discover their true heritage, embrace their faith, and learn what it means to make the ultimate sacrifice.
