Note on the age and birthday: Because the MDs were all Workers before the AbsoluteSolver took full control of Cyn's body, their exact age is undefined. At minimum, MDs are 18+ (most of them were 18 when they were Workers, though it's impossible to tell how many years it's been since they were turned into Murder Drones).
Note that a Drone's age is determined by how long the Drone has been active since it came off the assembly line, not counting however long a Drone individual might've been disabled, therefore a Drone's "birthday" would be its date of activation.
