Tilly, Tarquin, Teddy and Theodosia went to the New Eton Grammar school together. The finest education money could buy. They were children to families of eccentric trillionaires who had kids using surrogates as part of an elaborate bet brought on by boredom. 

Unloved and uncared for, they became bullies in school, failing miserably in all academic endeavours. After school they all applied to the New Eton Police Department, but were rejected as they failed to work as part of a team and scored low on the aptitude test. Their examiner said they only thing they excelled in was…cowardice!

When Tilly was rooting around in one of their family estates, looking for something to do, they found some old Spyrer Hunting rigs. These were advanced weapons suites from a bygone age, in which their ancestors needed more than money to defend themselves against the detritus of the world, looking for their “fair share”! 

Tilly and the gang donned the suites and set out into the underhive to bring “peace” to those who thought they wanted freedom. They were originally called the New Eton Police Department. But after a strongly worded cease and desist letter from the NEPD, they settled on the New Eton Peace Officers. Or NEPO for short. (For obvious reasons New Eton had banned the teaching of nepotism in schools, so the irony was in fact lost on them.)
