"Join us in Paradise or we'll send you to Hell"
With a strap line like that, it is no wonder the Neo Christian Union took their followers and retreated to fringe space. Whether to avoid persecution or because their extreme views are unwelcome to many civilised people across known space, it was decided to colonise a system of planets out of the way. God willed it.
That was a long time ago. The Paradise system became something of a Bermuda triangle and was to be avoided. In recent decades, however, NCU Missionary Forces have been spotted pushing further out of the Paradise system. Missionary outposts have been found on a number of planets nearby including New Charon.
New Charon had, however, already been settled by the Freehold, a commune of quasi religious folk who felt by escaping the central systems they could keep themselves clean of the evils of cybernetic human "enhancement".
Below we have a typical Missionary force, bringing the light of Truth to the heathens.
Mechs are Iron Wind Metals, infantry are Brigade, light cavalry are GZG.
