The Shadow War is over. The Shadows left the galaxy, going beyond the Reach. The young races work together in peace and harmony as part of the noble United Alliance, under the leadership of the Blessed Delenn, and under the protection of the formidable Dark Star fleet led by the "Shadowkiller", General John Sheridan. The Narns and the Centauri have reconciled, the Minbari are reforming their Gray Council, and Z'ha'dum is a world that is guarded day and night by the Vorlon fleet.

He came a thousand years ago, a Minbari born not from a Minbari. He brought them victory and hope, and he changed their society for ten centuries. But who was he? Who were those who supported him and those who betrayed him? Who were those who loved him and those who hated him? And the greatest question of all is where did he go on that memorable day when he left this world? The time has come for all questions to be answered and more than one mystery to be revealed.
