- — Isobel Derant
Isobel Derant was cousins with Sebastian. Her father was the half-brother of Sebastian's mother, Diane de Poitiers. Isobel's father was recently killed and suspected of being a traitor, and her baby's father was killed not long after.
She is a little quiet, but very witty to those she is familiar with.
Isobel and Bash grew up together. Bash would often visit with food and other items when he came to her village.
Isobel was accused of stealing and is sent to jail while her house is searched. She later escapes with Bash, Queen Mary and Alec, who helped her get to a safe location to try to get her to safety. Unfortunately, her baby was due too soon, which prompted them to stop the carriage in the middle of a forest full of pagans. Isobel then gave birth to a baby girl, but died shortly after due to excessive bleeding.
