Garan was Cinder’s stepfather, Adri’s husband, and Pearl and Peony’s father. He adopted Cinder when she was 11 years old in Europe, and shortly after returning to the Eastern Commonwealth, he died of letumosis. Dr. Erland reveals to Cinder that Garan was the one who performed the operation to make her a cyborg (human/robot hybrid), and he put a biological “lock” on her Lunar gift (the ability to telepathically control others) so that other Lunars couldn’t manipulate her.
