Rizon Phobas was one of the first Dragonlords, Second in Command to Xander Huorath and a great sorcerer. She helped Xander and Damon create the Oath of the Dragonlord.
Rizon survived the longest of the Dragonlords, if you exclude Damon, dying naturally of old age. Her bloodline continues in Estoria to this day with her descendants Therikles Phobas and Corinna Phobas.
Her tomb at Telemok is lined with murals of grand battles and depicts her riding a great bronze dragon. The climax of these scenes sees her triumph over a number of Minotaurs, with minotaur skeletons carved into the surrounding panels. The final panel shows some of these minotaurs kneeling and swearing fealty to her.
Rizon was also the author of the Xanderiad which details some of the original Dragonlords' history.
