Decisive Spade (1)

Even when he was only a Crown Prince, it was necessary for Spade to study the history of the noble houses that would soon be under his rule. And that was not included in knowing the history of the empire itself or the world's current or past situation. 

It was for him to know their allies and competitions; even the Empire, which was said to hold the hegemony in the world, needed balance for the world, or they needed it the most. 

The House of Ford was a Marquis noble house that was also one of the most important noble houses in the Empire. And as it was also part of the Royal Faction, it was investigated through and through. However, noting that a traitor was revealed among their ranks, Spade recalled their history to see if he could gather some clues.
