Isadore was Xander Huorath's granddaughter. She became the leader of the Dragonlords after the death of Telemok Arkelander and Cosmo Phobas. Rizon Phobas noted in her writings that Isadore was a worthy leader, with the courage and foresight to resurrect the order, but that "she died too soon."
During her time as leader, Damon returned to Mytros to be her advisor. Her murals at the Necropolis at Telemok feature him heavily and it is clear he cared for her a lot.
A great athlete, Isadore spent much time in Isadosia, which was renamed in her honour after her death.
