Adelaide Bichass
Sister to Carlos Bichass and previously an Imperial Princess, Adelaide was never quite right in the head. She has never had children, though she raised Run as a foster child at the royal palace at Tasset. When the baby grew to be a young man in a period of a few years, Adelaide cracked. She had retired to the family estates in remote Acacia before her brother was deposed and has been allowed to remain there. It's unclear as to whether Marathon allows this because he thinks she's harmless or if he actually harbors feelings for her as his foster mother.
