Konstantin Valdor. A name that evokes images of heroism, honor and an unsurpassed sense of duty. After all, he is the one to whose will the Legio Custodes, the most respected and loyal army of elite warriors, submits. He is the sword of the Emperor, His shield, His banner, which has no equal. Clad in shining auramite and clutching the spear of the Guardian, he is a bastion of defense against all enemies of the throne, both within and without. By the end of the Unification Wars, Valdor's courage and determination are tested as never before. The petty tyrants and warlords of Old Earth are almost defeated, the Emperor's army celebrates victory. What awaits the nascent Imperium, and what will be the fate of its forgotten soldiers - the Thunder Warriors and the armies of the Unification? A new force is gaining weight. It will outshine all others and open the way to the stars. But change on Terra rarely comes without bloodshed, and dark deeds are needed to ensure progress.
