Juliet Maupin (SEY 2747 - 2862) was a weapons and scanner engineer. She began her career at Aegis Dynamics as a machinist in 2766, eventually transferring to the ships team on Cestulus (Davien II) in 2772. There, she worked her way up to lead engineer and led the team responsible for the 2783 revamp of the Retaliator bomber. Following that success, she was enlisted by the United Empire of Earth (UEE) military to produce a new line of powerful and advanced weapons for the Messer government.
Maupin fled with her family to the Corel system after the events of the Anti-Messer revolution for fear of being associated with the former regime. A crate of Maupin's prototypes that never made it to the Kilian system for testing was discovered in a Cestulus warehouse in 2911 by Dalton Colabello, who went on to use them as the basis for the debut line of weapons for his new company Apocalypse Arms.
