Orlex was a baatezu devil lord who ruled the ancient kingdom of Yhalvia, which was part of the empire of Narfell (−946 DR to −150 DR). His reign was naturally cruel, depraved, and wicked. A band of rebellious wizards arose to depose Orlex. Led by the archmage Thakorsil, they created the throne known as Thakorsil's Seat to imprison and permanently bind and enslave the evil fiend. Unfortunately, although they had the best of intentions, the device demanded deeds of despicable evil to function. Thus, they devised the ritual of twin burnings, which involved the sacrifice of beings of good heart, believing this was for the greater good, that the ends justified the means.
