Unfortunately, the Sword-Worlds have gone into their own decline just as the League of Civilized Worlds is faced with its greatest defeat. Soon, the first real threat to Space Viking domination must be overcome and brought to heel. Will the disparate Space Vikings join together, or be sent packing back to the Sword-Worlds in defeat?
Captain David Morland of Joyeuse? might well be the last of the great Space Viking captains. He emerges at a time when the Old Federation is changing, and not for the better.

But first, Morland has to find the right world and conquer it before he's discovered by a new power determined to end the Space Viking menace, one way or another!
