Stars Without Number
Description
The year is 3200 and mankind's empire lies in ashes.
The Jump Gates fell six hundred years ago, severing the links between the myriad worlds of the human diaspora.
Now, the long isolation of the Silence falls away as men and women return to the skies above their scattered worlds.
Will you be among them?
