In 2618, a group of political activists and refugees, fleeing the Messer regime, moved into a vacated mining facility located on Delamar, a moon-sized asteroid deep within the system's asteroid belt. Discovered in 2582, the Nyx System was left unclaimed by the UEE after deciding its three planets were not terraforming candidates and attempts to mine the dense Glaciem Ring were deemed too dangerous.

The Nyx system is an unclaimed system located slightly south of former Perry Line, directly on the border of a dark nebula.
