Sarmondelaryx, also called the Bane of Thrane, and the Angel of Fire, was a red dragon who went on a rampage in Thrane and areas of northern Cyre in 22 YK, just years after the formation of the Kingdom of Galifar. Prince Thrane rallied an army to face the rogue dragon, but she slaughtered him and scattered his army. The area that the battle took place was devastated, and became known as the Burnt Wood.
She suddenly vanished several weeks after her murder of Prince Thrane and the desolation of the Burnt Wood, and there have been no reported sightings of the Bane of Thrane since.
