Servo

A servo is a multi-function device that resembles a pen.

It was employed by Gary Seven, a man whose Human ancestors were abducted from Earth around 4000 BC, and taken to another planet.

The servo had several functions, and served as:

• A communicator, which allowed Gary Seven to communicate with his computer and initiate transport.
• A personal defense mechanism. It had both a stun setting, which made its target go into a hypnotic state open for suggestion, and a kill setting.
• An electronic manipulation device, which Gary Seven used to deactivate the force field keeping him in the brig.
• A mechanical manipulation device, with the ability to serve simple purposes such as unscrewing screws, and locking and unlocking doors.
