And Sirzechs, Ajuka, Serafall, Falbium, and Grayfia were born at the end of the great war. Well I believe the Great War was still going on although the Fallen Angels withdrew from the war and the devils were busy fighting among themselves. And after the Old Satan faction lost, they put the new Maou in their positions. And they were able to end the war. Although they still had skirmishes over the years. And Ajuka created the evil pieces system in the 1500s based on Lord Gremory's bishop, Heinrich Cornelius Agrippa, who is a real person and died in 1535.

And Sirzechs probably took so long creating his peerage because he was a Maou and had to have very powerful servants.
