Settlement 228 is a frontier world in the Golgenna Reach of the Calixis Sector. A new colony (established four hundred years ago), seating eighteen thousand families on a dry, harsh settlement world. Though “cram beans” have proved a reasonably successful export crop, there is great unrest within Settlement 228’s plantation farms. The settlement families, all exported from Scintilla, believe they were sold their land rights fraudulently. They claim that the planet is nothing like as viable as they were led to believe from the surveys. There is a strong anti-Imperium groundswell here and a hard-bitten drive towards revolution.

It has many moons, one of which is Designate-228-18, recently discovered to possess vast ruins of xenos origin.
