Simone Devon was an officer with the St. Ives Military Command.
Promoted to General, she died during the Black May affair. The attack on St. Ives by the Thuggee was to be launched by a JumpShip, the You dú Xin-Zàng, carrying a single DropShip and a lone old Lucifer fighter loaded with rockets of the gas, but the JumpShip during the final jump, using a pirate point, suffered a missjump and was almost destroyed. The crew was killed or left half dead. The ship was boarded by a Compact rescue team lead by Davion general Simone Devon, but when they found the Lucifer pilot still in his cockpit, he launched the rockets, killing the general and probably most of the other people aboard.
