User Summary: A set of adventure/sourcebooks for Fading Suns which cover encounters with alien races. Originally intended as a trilogy, only the first two volumes were published. RedBrick, the current publisher, has indicated that the final volume remains unlikely to be produced.
From the back cover of War in the Heavens: Hegemony:
Ever since the Vau gave humanity its first setback among the stars, their space has been shut to prying eyes. For a brief moment, however, it has opened - long enough for the most daring to catch a glimpse. But the daring need as much wisdom as courage, for encounters with the Vau teach that things are not always what they seem....Future installments in the War in the Heavens Trilogy feature the alien Vau Hegemony and the Anunnaki jumpgate builders.
