In time, 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. They went ahead with the horrific rites, and successfully bound and enslaved Orlex in the Seat.
Afterward, they formed a council of wizards that governed Yhalvia. However, corrupted by the sacrifices and with Orlex as their slave, they soon became as cruel, depraved, and wicked as the devil they had replaced. In time, others overthrew them, Orlex was banished to the planes and Thakorsil's Seat was lost and believed destroyed.
- ↑ The earlier sources suggested that Yhalvia "may have been located on another world altogether", but the Forgotten Realms Campaign Guide made it a part of ancient Narfell. This article assumes this to be the ancient empire of Narfell, rather than the later land of the same name, but the date of Yhalvia remains unknown. However, Narfell is known for its close links with demons, so the appearance of a devil with such power is unusual.
