During their efforts they discover the land is only one of many on a world that, millennia ago, had been constructed about a black hole like anomaly.

Three Earthmen must find a way to thwart the invasive creatures, stop a war between two kingdom like 'RELMS', and solve a riddle plaguing an empire for a thousand years.
